Published: December 2019

This paper presents the results of the study of various pathomorphological forms of breast tumors in the population of domestic cats of the Rostov region. 73247 case histories were analyzed in 8 leading veterinary clinics of Rostov-on-Don and Bataysk city, and also 30 resections of a breast were made with the subsequent histological research. The incidence of breast tumors in the population of cats of the Rostov region in 2018 was 438 animals per 100000. According to the results of 187 cytological findings, “malignant neoplasm” was diagnosed in 53% of cases (48% - carcinoma, 5% - sarcoma). The histological examination revealed malignant tumors in 80% of cases (77% - invasive nonspecific carcinoma, 3% – malignant leaf-shaped tumor). Taking into account the fact that about 1.5( ± 76 thousand) million cats live in the Rostov region, it can be assumed that 0.44% (p-95%, confidence interval 0.38%-0.50%) will have a breast tumor, about 80% (p-95%, confidence interval 55%-94%) of which will be malignant.

Published: December 2019

To determine the prospects for the use of new winter crops (triticale, barley) in addition to traditional crops (winter wheat and winter rye) in order to diversify the winter wedge, studies were conducted on the basis of the Samara Research Institute of Agriculture and the Samara State Agricultural Academy from 2004 to 2018. Weather conditions over the years of study were characterized by high contrast. The effect of various ratios of wheat and triticale flour on the quality of bread was studied. When conducting test baking, the best quality bread is obtained from a mixture: wheat flour 50% and triticale flour 50%. As a result of breeding work, two varieties of winter triticale Krokha, Kapella are zoned, and two varieties (Spica, Arktur) are in the state variety test. It has been established that the limiting factor affecting the formation of the yield of winter barley grain in the Middle Volga region is the low temperature at the depth of the tillering node. The years are determined, characterized by favorable and unfavorable conditions for the wintering of winter barley. The best for wintering in the Middle Volga region is a variety of winter barley Zhiguli. When fertilizer was applied, winter barley formed a higher yield (2.03…4.80 t/ha) compared to winter wheat and triticale.

Published: December 2019

The conducted analysis of the technical provision of machine-tractor fleet of Russian agricultural enterprises for the implementation of crop production technologies revealed a lack of technical support of agricultural production, which leads to a reduction in acreage or stretching of agricultural terms of technological operations. All this leads to a significant loss of agricultural products. The qualitative conditions of enterprises are described by four stable zones, which are directly dependent on the level of technical equipment of production: a zone of minimizing the scale of production, and in many cases the termination of the enterprise’s operation; zone of extended agrotechnical terms of technological operations; zone of optimal agrotechnical terms established by the requirements of technological maps; zone of strengthening the protective properties of the enterprise and increasing the reliability of its operation. The method of determining the need for agricultural machinery was developed, which showed that the best level of technical provision is a level that ensures reliable performance of all technological operations in the optimal agrotechnical terms, on the basis of which the boundary conditions of technical security are developed.

Published: December 2019

The process of obtaining expected physical and mechanical properties of protective coating, which is applied on machine elements in complex acoustic field by electroacoustic method, is conducted with the use of highly concentrated sources of electric energy. Prediction of physical and mechanical properties of the reinforced surface of machine parts is made on the basis of the experimental design technique with nonorthogonal planning matrices. Mathematical models were tested for adequacy on the basis of Fisher’s variance ratio. A structural scheme for microprocessor control system of electroacoustic spray coating was developed. The physical basis of the mass transfer of materials to the substrate in a complex acoustic field is developed, which is done by transforming longitudinal vibrations into longitudinal-torsional ones, while the amplitude of the acoustic system oscillates from 5 to 15 micrometers. The use of longitudinal-torsional ultrasonic waveguides in this process and ultrafast cooling temperatures allow the formation of such elements as carbides, carbonitrides, intermetallics on the surface of the conductive material. The subsequent shock produced by the waveguide-electrode with a shift to the surface leads to irreversible microflow of the surface layer, which provide the specified parameters of the surface quality and its physical and mechanical properties (microhardness and roughness). The thickness of the sprayed layer is 6-8 micrometers, and the thickness of the plastically deformed layer is 30-45 micrometers.

Published: December 2019

The problem of eimeriosis today is no less relevant than in past years. Eimerosis is dangerous not only by itself but also by association with other diseases. Current conditions dictate the need to improve preventive measures through the development of new high-performance anticoccidial drugs. In this regard, the effectiveness of some anticoccidial drugs was compared in experimental eimeriosis of broilers. To perform the task, the bird was infected with a mixture of oocyst Eimeria (E. acervulina, E. maxima and E. tenella) at the week-old age. The treatment of the chickens in the experimental groups started at the 12th day after infection using various drugs: toltrazuril, sulfachlorpyridazine and combined products (sulfadimidine and trimethoprim). On the second day after the start of anticoccidial drugs feeding, there was a positive dynamics in experimental groups – decrease of allocated oocyte. Almost complete cessation of their isolation was recorded on 3-4 days of therapy. At the second day of treatment, birds increased activity, appetite, clinically it looked more cheerful, feces acquired a normal consistency and color. It was found that the use of anticoccidial drugs inhibits the development of Eimeria and contributes to high safety of birds, promotes their normal growth and development. Thus, the productivity of chickens increases by 600 g compared to untreated poultry.

Published: December 2019

One of the main promising directions in the development of pharmacology is the development of selective drugs and effective approaches to their production using nanoscale drug delivery vehicles. Providing the necessary therapeutic concentration of drugs in target cells is not an easy task. To solve it, a specific drug carrier is required. The most promising is the use of biodegradable delivery systems, due to the lack of the need to use expensive equipment, and it is also possible to synthesize them in production volumes. The need to develop systems for the controlled delivery of drugs, especially antibacterial drugs, is due to their clear advantage over antibiotics in standardized dosage forms. Increasingly, in poultry industry, high mortality rates of chickens began to be observed in the acute form of enterotoxemia due to Clostridium perfringens and its associations with another microflora. The aim of this paper is to study the therapeutic efficacy of a free and included in biodegradable system antibacterial drug (cefotaxime) for bacterial infections in birds. There were formed 3 experimental and 1 control group of broiler chickens of the cross Cobb-500 daily age of 15 animals each. At the age of 10 days, the birds of group 1-3 were orally infected with virulent diurnal cultures of microorganisms: Clostridium perfringens. During the experiment, daily monitoring of the general condition and behavior of the birds, consumption of feed and water was carried out, the clinical status of the sick birds, the time of onset of positive dynamics and the time of recovery were evaluated. After completing the course of therapy, monitoring of the state of the birds continued for 7 days. After completion of the experiment, bacteriological examination showed that the use of cefotaxime at a dose of 10 mg/kg for 7 days does not eradicate Clostridium perfringens, while the use of cefotaxime based on chitosan and cefotaxime based on exosomes at a dose of 10 mg/kg provides 100% therapeutic efficiency.

The successful development of the world sheep breeding is due to its meat productivity. In this regard, dorper meat breed gained its popularity, which has good meat qualities. The aim of the paper was to study the histological structure of the longissimus muscle of back of young rams of Kalmyk fat-tailed breeds and hybrids (1/2 Kalmyk fat-tailed + ½ dorper), as well as to establish a correlation between histological indicators of muscle tissue and slaughter and meat qualities. The work was carried out in LLC “Agrofirma Aduchi”, Republic of Kalmykia in 2016-2017. It was found that the muscle tissue of crossbred young rams was characterized by a large number of muscle fibers per unit area, a smaller diameter of muscle fiber, a higher rating of “marbling”. The content of connective tissue was greater in purebred rams than in crossbred ones. The area of the “muscle eye” was larger in crossbred animals of the second group. In the animals of Kalmyk fat-tailed breed, the coefficient of variation in the number of muscle fibers per mm2 was high and made up of 7.36% for the overall assessment of “marbling” to 10.59%, the content of connective tissue – 5.94%, which is higher compared to crossbred animals. Muscle tissue of crossbreed young rams is characterized by significantly more muscle fibers per unit area, smaller diameter of muscle fiber, and a higher rating of “marbling”.

A necessary link in the life of any cell is lipid peroxidation. This process underlies the renewal and restructuring of biological membranes, regulation of their composition, permeability and activity of membrane-bound enzymes. The increase in the level of POL (peroxidation of lipids) leads to oxidative stress, which provokes the formation of various pathological conditions in the body. One of the main components of the antioxidant protection of the body is a group of metal enzymes - superoxide dismutase (SOD), catalyzing the dismutation reaction of superoxide anion radicals and maintaining the concentration of these radicals in the cell at a low level. The mechanism of SOD functioning includes sequential renewal and oxidation of metal ions of variable valence in the active center of the enzyme. SOD is an endogenous acceptor of free oxygen radicals, the excessive accumulation of which in the cell is important in the development of a number of oxygen-dependent pathological processes (hypoxia, inflammation, intoxication, etc.). SOD removes superoxide radicals and prevents the formation of other, more dangerous for the body free radicals: hydroxyl radical and singlet oxygen. The activity of superoxide dismutase in blood and tissues is a marker of metabolic disorders. During the study of the relationship of the distribution of catalase activity in serum and tissues of rats, the following tasks were solved: the activity of SOD in serum and tissues of the liver, brain, heart, as well as in skeletal muscle tissues of rats was indicated; the relationship of the distribution of SOD activity in serum and tissues of rats was revealed. The paper presents the results of nonparametric correlation analysis to assess the relationship of the distribution of SOD activity in serum and tissues of small experimental animals.

Published: December 2019

The directions of increasing the efficiency of livestock production based on the use of advanced technology and controlled digital technologies for performing processes are considered. The influence of technological, technical, organizational and economic factors on the growth of product competitiveness is shown. The purpose of the study is the justification of a set of measures to increase the competitiveness of livestock products based on the implementation of engineering, technological, organizational, economic, and environmental factors. In recent years, milk production in the country has been ensured mainly by increasing the productivity of cows in agricultural organizations while reducing their numbers, and the tendency for a decrease in milk production in households is steadily continuing. One of the reasons for this is the low level of technical equipment of the facilities, due to the lack of specialized enterprises for the production of innovative equipment in the country, the slow pace of machine renewal, and the use of ineffective technologies for keeping and feeding animals. Measures have been proposed to increase the investment attractiveness of livestock and, especially, dairy cattle breeding, creating conditions for its growth. It was recommended to analyze and select the best investment projects for the creation and modernization of existing livestock breeding complexes and farms and take measures for their distribution, as well as take measures to revive specialized mechanical engineering for livestock breeding and develop a program for the technical equipment of livestock industries. The results of the study should be used in developing programs and directions for improving state support for livestock breeding, ensuring food security in Russia, and addressing issues of import substitution.

Published: December 2019

Composite materials are becoming increasingly useful in engineering practice. They allow considering work aspects in the elastoplastic field. This is especially important for the systems that are modeled on geometric non-linearity. These systems include constructions which bearing capacity is provided by flexible threads, such as wires in bee honeycombs. An example of such a construction is the described centrifuge for honey or beebread mass extraction from a honeycomb (honey extractor), using frames for honeycombs with reinforced flexible wire. Comparative studies were conducted using previously tested computer programs based on the methods of linear and non-linear calculation of flexible wires. The deformation values of flexible wires were determined with consideration of the rotation frequency of the centrifuge rotor. The diagrams of changes in maximum expansion stresses, elongation of the wire, sagging of the flexible wire, the moment of inertia of the elastic body, equivalent loads for the methods of linear and non-linear calculation of flexible wires at different rotor rotation frequency were developed. When modeling objects with a rotating flexible wire, it is possible to use methods of both physically non-linear calculation and more simple and accessible linear calculation. Using the latter method, the calculation results should be divided by nonlinearity coefficient.

Published: December 2019

The wheeled running gear of an agricultural tractor must have sufficient traction and coupling properties to ensure that the tractor fulfills its main function. The solution to these problems depends to a large extent on the search and implementation of measures for improving and developing new tire designs, which are the main element of the wheel drive that meets modern requirements. The developing of new pneumatic tires requires creating a new formulation of rubber and materials, the use of rubber-oligomeric compositions that allow implementing new, advanced technologies in the manufacture of tires. Currently, tires based on rubber-oligomeric compositions are being created. In particular, the Austrian company Lim developed a range of wide-section tires based on oligomers. As a result of tests of tires for class 3 tractors, it was determined that the oligomer tire 66×43.00-25 has the best traction and energy performance on all supporting foundations, compared to the serial tire 21.3R24.

Published: December 2019

The economic growth associated with maximizing profits from the use of natural resources and the environment has exhausted itself. The ideology of organic farming implies an optimal combination of the interests of the rural population, consumers of environmentally friendly products and a healthy environment. In recent years, the idea of using a national Baikal brand in the food market has been widely demanded and relevant. Such a pioneer product is the production of bottled Baikal water that meets international quality standards. An obstacle to the wide access to the world market for this product is the legislative restrictions in most developed countries on the consumption of drinking water from open sources. However, the upcoming world water crisis will open up prospects for a wider use of Baikal water, primarily, in densely populated Asian countries. In recent years, breeding of native breeds of farm animals adapted to the local climate, which comply with the principles of organic farming, has been revived in the Baikal region. In addition, the proximity of the external export market determines the possible production of specific “halal” products that are targeted at Southeast Asian countries with a predominantly Muslim population. In Mongolia, practical steps have been taken to produce “religious-specific” organic products, including the national quality standard for “halal” products. The high quality of meat products based on pastoralism corresponds to the rules of kosher food. Strict laws of “kashrut” may correspond to beef and lamb, as well as high-quality fish products of endemic species of the Baikal basin. These factors give a particular specificity to the concept of organic products, which combine the quality of ecological products with the uniqueness of the Baikal brand, the national specificity of Buddhism culture and traditions of oriental culinary.

Published: December 2019

The issues of selecting parameters and operating modes of a system designed to remove ammonia from a pig-breeding module are considered. The aim of the work was to justify the scheme of the suction device layout of exhaust ventilation, which ensures the removal of ammonia from the animal keeping area at the lowest energy costs and maximum economic effect. The analysis of the effect of gases on the animal organism is carried out. The parameters of the exhaust ventilation system at the maximum air exchange in the pigsty are determined, taking into account the constantly changing parameters of the outdoor air and animal groups. Mathematical models are proposed that describe the dependences of changes in the radius of the spectrum and the active absorption front on the geometric and kinematic parameters of the harmful gas removal system. The method of comparing the layout of the suction pipes was used to identify the most effective scheme for removing ammonia from manure channels. The energy costs of using exhaust systems are determined. A technical and economic assessment of the proposed layout options for suction devices is given. Various layout options for suction devices are considered. Dependencies between the geometric and kinematic parameters of the system are established. Based on the feasibility study, the scheme of the ammonia removal system that provides the greatest economic effect is determined. The results can be used in the development of ammonia removal systems from pig-breeding facilities. The proposed mathematical models make it possible to determine the most rational arrangement of the suction devices for the most efficient removal of ammonia.

Published: December 2019

Green manure is an important source of replenishment the missing amount of organic and mineral fertilizers for modern agricultural enterprises. Therefore, the aim of the study was to identify the role of green manure crops in increasing soil fertility and crop productivity. The plowing of the green mass of the under-cover clover for green manure provided the optimum values of volumetric mass, porosity and air capacity, as well as higher moisture content in the soil layer of 0-30 cm. The intensity of cellulose decomposition in winter wheat crops 4 months after plowing of clover in the soil layer of 0-10 cm was 52.3%, of 10-20 cm was 50.9%. Subsequently, the yield of winter wheat according to the variant with clover green manure was higher than without green manure. The intensity of the negative impact of burning straw on soil fertility indicators depends on its mass, stubble moisture, and topsoil. Plowing straw and applying nitrogen fertilizers under the stubbly green manure crop - spring rape - contributed to an increase in organic matter, which positively affected the quality and yield of potato tubers. On average, for 3 years, the combined use of straw, nitrogen fertilizers and green manure contributed to obtaining the largest potato crop, while the increase in comparison with control was 34.0%.

For the first time, the composition of a feed additive from modern biologically active substances and natural components with a synergistic effect has been scientifically substantiated, which is capable of forming biologically complete, environmentally friendly products in animals at the final stage of growing (a month before slaughter). This additive consists of,%: 95.5 – micronized full fat soya (source of leucine – controller of adipopexis), 3.5 – betaine (osmoprotection moisture retention in muscle tissue), 0.3 – L-carnitine (an activator of energy metabolism), 0.7 – Lisofort (emulsifier of fats, improving its digestion). It was found that the use of a functional feed additive in the amount of 2.0% 30 days before slaughter of pigs increases its productivity by 9.3%, reduces feed costs for products by 8.4%. In muscle tissue, fat content increased by 0.85 %, characterizing the improvement of “marbling” of meat. The moisture-binding ability increased by 8.0%, the color intensity by 5.0 units of extinction, and a protein-quality indicator of meat due to an increase of 4.68% in the content of essential amino acids. The economic efficiency of the use of functional feed additives for the final fattening of pigs was calculated.

Published: December 2019

The North Caucasus region in its natural and climatic conditions is a zone favorable for the cultivation of corn in Russia. Significant damage to corn plantings and crop quality is caused by a variety of pests. In connection with the annual crop losses caused by harmful insects, the development of methods for their monitoring and capture are relevant. The efficiency test of two designs of light traps based on super bright LEDs (conical and aspiration) was performed. As a result of the experiment, which lasted for two weeks, more than 260 thousand specimens of insects belonging to 8 orders and 27 families were captured. The traps were most attractive for the representatives of the coleoptera, the proportion of which was 97.5%. Traps were also highly effective in relation to Lepidoptera (1%) and Hemoptera (1.4%). Representatives of other taxa were caught in much smaller quantities; their total share was less than 0.1% of the total. The use of test traps showed their high efficiency for the elimination of the main lepidopteran maize pests - Helicoverpa armigera Hbn. and Ostrinia nubilalis Hbn., which allows them to be used not only for monitoring but also for plant protection. The low attractiveness of traps for Hymenoptera was also revealed, which allows combining their use in the system with the use of entomophages. A comparative assessment of the effectiveness of attracting insects with various designs of light traps in the corn agrocenosis showed the absence of significant differences in species diversity and mathematically significant differences in the number of attracted insects: the conical trap was almost two times more effective.

Published: December 2019

This article reviews the methods for calculating the distribution of river sediments in channels. As a result of the analysis, initial methods for the distribution of sediments on the channels was developed for straight and unstable rivers. A mathematical model that describes the distribution of river sediments during uneven movement in the structures has been developed. The distinctive feature of this model is that the distribution of sediments in the stream depends on the fractions. In the hydraulic structures, a mathematical model of turbulent flow was proposed during the uneven movement and based on this model; a method of calculating sediment distribution was developed in a non-linear motion. Comparative analysis of model of calculation of river sediments in constructions was verified with analysis of natural field conditions. The analysis of the results shows that the difference between the measured values and calculated values is 4-8%.

A nutritious and safe diet maintains human health and endurance. In addition, it preserves the national gene pool. Unfortunately, Russian diet is poor in vitamins C, PP, B1, and E, as well as in folacin, calcium, phosphorus, iodine, iron, magnesium, and zinc. The present research introduces a new method of assessing the degree of demand for designing new foods and dishes that provide various socio-demographic groups with essential nutrients. The research employed standard scientific methods, both empirical and analytical. The new method presupposes scoring four main sets of properties of the product under development. They include 1) formula components; 2) functional properties; 3) technological effectiveness of the cooking process; 4) consumer performance. The paper describes the score assessment for each indicator that forms the basis of each set of integrated properties. It also defines the weight coefficients for each indicator and each set of product properties. The research provides boundary values for the feasibility coefficient. The practical application of the proposed method allows to create functional competitive dishes for catering enterprises of different ownership forms. The developed method makes it possible to design functional dishes with a sufficient content of nutrients and consumer performance required for a particular social group, e.g. pre-schoolers, school children, coal miners, chemical industry workers, etc. The method will allow producers to design competitive products and expand the range of functional products.

Heavy metals concentration in arable soils of the Vladimir region range as follows (min → max): Cd-0.13-0.36 mg / kg; Cu – 2.11 - 10.2 mg/kg; Co – 2.62 – 7.9 mg/kg; Pb – 3.43 - 10.2 mg/kg; Ni – 2.78 - of 15.6 mg/kg; Zn – 12.5 – 35.6 mg/kg; Mn - 136 - 541 mg/kg. Calculating the hazard ratio, the series is presented differently: Cu →Pb →Mn →Co→Zn→Ni→Cd. In comparison with background indicators gross content increase of the following elements occurred in the region: Pb (17.2%), Cu (13.5%), Zn (1.3%), Co (17.4%). Cd and Mn slightly decreased. Ni showed no changes. Fertilizers are the main source of HM in the arable layer. The research show that heavy metals gross content in the arable soil layer in the region does not exceed MPC; thus, arable soils in the Vladimir region are slightly polluted with heavy metals and are not harmful to human health.

Published: December 2019

The paper identifies bioclimatic comfort zones of the Krasnodar Krai. The studied bioclimatic indices take into account the combined influence of temperature, wind speed, relative humidity, atmospheric pressure, solar radiation in various combinations. The geoinformation analysis of the following bioclimatic indices was carried out: effective temperature, equivalent effective temperature, bioclimatic active temperature, radiation equivalent effective temperature, and a comprehensive indicator of the level of pathogenic weather in the Krasnodar Krai. The pathogenic weather index is the only index considered in this paper that takes into account atmospheric pressure. Comfortable months for living in the Krasnodar Krai have been established, as well as areas of the Krasnodar Krai that are favorable for living at any time of the year. However, peak values are not necessarily adverse. During these periods, sometimes healthy people experience an improvement in mood and a surge of strength, while overworked ones respond by aggravation of their condition. Thus, the Krasnodar Krai was divided into 4 comfort zones: Azov-Black Sea, Black Sea, South-East foothill and continental.

Published: December 2019

The transport and logistics market make high demands on the speed of decision making and their economic feasibility. In the conditions of a dynamically developing market of transport and logistics services, decision-making must be carried out quickly, on the one hand, and reasonably on the other. The adoption of such decisions in complex terminal systems for the delivery of goods requires the use of methods that allow such a comprehensive assessment. Obviously, the methodology should be objective and consider many factors of the work of the terminal and logistics complexes. This circumstance determines the relevance and purpose of this work - the development of methods for integrated assessment of the parameters of the terminal and logistics complexes based on the total rating. To achieve the goal and approbation of the methodology, we used programming tools in the Scilab environment, as well as methods of systems theory, terminalistics, logistics, economics, organization and planning of railway transport operation, expert assessments, SWOT analysis, calculation of parameters of freight fronts, score ratings, linear and dynamic programming. The practical significance of the results obtained in the study is to develop applied assessment tools for conducting an express analysis of the activities of terminal and logistics complexes on several key parameters. The subject of future research may be to solve the problem of reducing the subjectivity of evaluation by this method.

Authors: Habibulla Turanov , Elena Timuhina , Andrej Gordienko
Published: December 2019

The effect of the tailwind on the wagon when it is rolling down from the hump is discussed. The movement of the wagon on the profile of the marshalling hump is studied. The article applies the theorem on the addition of velocities in complex motion in vector form. Errors in determining the specific resistance to the movement of the car from the air and wind arising from empirical relationships taking into account the aerodynamic characteristics of the cars are mathematically substantiated. The results of the research can be used in the processing of the normative-technical document on the design of hump devices on railways and making adjustments to the dynamics of rolling the wagon in textbooks for universities of railway transport. The results of this study prove the need to revise the practical significance of the formula for finding the specific resistance to the movement of the car from the air and wind in the normative-technical document “Rules and regulations for the design of sorting devices on the railways track gauge 1 520 mm ".

Authors: Habibulla Turanov , Elena Timuhina , Andrej Gordienko
Published: December 2019

The height of the high-speed section of the sorting slide is studied. Design of high-speed section of the marshalling hump is discussed. The aim of the study was to mathematically prove the absence of theoretical basis of the formula by which the height of the first section profile of the marshalling hump is calculated in the current method for calculating marshalling humps. The paper uses the theorem on the change in kinetic energy for a non-free material point in the final form, known from theoretical mechanics. The results of the study showed that the formulas used to calculate the height of the first section of the marshalling hump contradict the theorem on the change in kinetic energy for a non-free material point in its final form. The results of the research can be used in the processing of the normative-technical document on the design of hump devices on railways and making adjustments to the dynamics of rolling the car in textbooks for universities of railway transport. The results of the calculations proved the incorrectness of the derivation of the formula for calculating the height of the first profile section of the marshalling hump in the normative-technical document “Rules and standards for the design of sorting devices on the railways with gauge 1 520 mm”.

Marine-derived fungi are of great interest as new promising sources of biologically active products due to its diversity in chemical structures and biological activities. The objective of this study was aimed to determine the cytotoxicity of marine sponge-derived fungi that collected from Kepulauan Seribu Marine National Park. The fungi were fermented in a static liquid culture of malt extract broth medium (containing 0.3% malt extract, 0.3% yeast extract, 0.5% peptone and seawater) for 3 weeks at 27-29°C. Bioactive secondary metabolites of fungi were extracted using ethyl acetate. Cytotoxicity of the extract was performed by using MTT assay. A total of 17 isolates were tested against T47D cell at a concentration of 30 µg/mL, among them, isolate of MFP270 exhibited the strongest cytotoxicity. Further analysis showed that mycelium extract of MFP270 had stronger cytotoxicity (IC50 = 28.3 µg/mL) than broth extract (IC50 = 645 µg/mL). The MFP270 marine fungal was identified as Aspergillus sp. base on its morphology features.
