Authors: Nita Victor Nicolae , Nenciu Magda-Ioana , Nicolae Carmen Georgeta
Published: September 2018

Recirculating Aquaculture Systems (RAS) used in aquatic research and production are a viable alternative to traditional open-sea mariculture. The rearing of marine living resources in controlled environments is one of NIMRD’s constant concerns. Golden gray mullet Liza aurata (Risso, 1810) is spread in the Mediterranean, Black and Caspian Seas, as well as along the Atlantic coast, and culture in extensive and semi-intensive enclosures has been practiced worldwide for centuries, especially in the Far East and the Mediterranean, reaching a global production of 134,329 tons in 2010. The species’ potential for aquaculture is enhanced by its eurihalyne and eurithermal adaptability, allowing it to grow in a variety of ecosystems. The biological material used for the experiment was represented by golden gray mullet fingerlings fished using the beach seine from the Black Sea. They were monitored for health state, growth rythm (mean length and weight determinations), behavior under RAS conditions, survival rate and overall adaptability. The growth of juveniles after 90 days was 89.2% for total length and 246% for mean biomass. Concerning overall adaptability, after approximately one month, the golden gray mullet individuals fully adapted to rearing in the RAS tanks and handling during measurements. Moreover, the food administered (Skretting Classic K) was easily accepted, active feeding behavior being observed even in the presence of NIMRD’s staff. The fish’s health state was good, with no mortalities caused by infections or parasites. The survival rate upon completion of the two monitoring months was 76.66% (23 of the 30 individuals included in the experiment). The preliminary results obtained showed a good adaptability and a normal growth rate, which makes Liza aurata a potential candidate for aquaculture targeting the national and regional market.

Authors: Totoiu Aurelia , Patriche Neculai
Published: September 2018

This paper aims to show the importance of knowing the health status of fish populations in their natural environment and its influence on fish stocks at the Romanian coast. To assess the interrelationship between fish health status and the state of stocks, the following fish species: turbot, sprat, anchovies and horse mackerel were analysed from the pathological point of view. Pathological analyses performed between 2015 and 2017 revealed the presence of infections caused by bacteria of the genus Aeromonas and Vibrio and parasitic diseases Trichodinosis, Botriocephalosis and Nematodosis. The presence of these diseases in natural fish populations may represent a real danger to the state of existing stocks, but also to their evolution.

Authors: Tüzün Ahmet Engin , Olgun Osman , Yildiz Alp Önder
Published: September 2018

The aim of this study was to investigate the effects of dietary supplementation with high levels of inorganic, organic or nano sources of two high-level zinc diets (200 and 300 mg/kg) on performance, eggshell quality and mineral content of bone in layer quails. The experiment had a 2×3 factorial arrangement of treatments. Egg production and the zinc content of tibia were significantly increased in the present experiment. Compared with zinc oxide supplementation, zinc-glycine supplementation increased zinc concentration in the tibia. The interactions between the sources and levels of zinc were a significant effect on egg production, eggshell breaking strength, eggshell weight and tibia zinc level. The highest eggshell breaking strength and eggshell weight were observed in the group was fed with diet including zinc-glycine at 300 mg/kg. These results suggested that zinc-glycine supplementation positively effects eggshell quality parameters and tibia zinc concentration when compared with other sources used in this experiment. Additionally, the supplementation layer quail diets with zinc-glycine rather than nanoparticulate sources of zinc could be recommended for optimum performance.

Authors: Cimpoies Liliana , Semionova Elena
Published: September 2018

For Moldova’s agriculture are characterized the existence of many small family farms and only a small number of corporate holdings (limited liabilities companies, agricultural production cooperatives etc). Most of individual farms, small by size produce only for own family consumption and cannot find their way to the market place. The accentuated poverty makes rural economy to flow more and more to a natural subsistence economy, isolating itself from the market economy. The goal of this paper is to delimitate different types of farms based on selected indicators and to appreciate their level of development. Differences in farms levels of development are appreciated through cluster analysis. The research includes the analysis of farms survey data. This research was carried as a part of the Academy of Sciences project “Sustainable rural development in Republic of Moldova in the context of EU accession”. In the project were surveyed 938 individual farms from nine districts across the country. As a result, we distinguish three types of farms: natural, family and market household. The cluster analysis allows to characterize the farms level development, to determine the main priority directions, and to elaborate measures for the individual farms further sustainable development.

Published: September 2018

Policies for ensuring food security have gained considerable importance in recent years. The policy success of the countries at this lower level is very important in ensuring food safety. It is also important to determine where the countries take place in food security. In determining the success of countries The Global Food Security Index (GFSI) takes on an important role. In order to prepare the index different subsections of food security such as food availability, food accessibility, food quality and safety are calculated using different weights. This index is re-prepared every year and allows the user to make changes using different weights and calculating rankings again. It will also include recommendations on agriculture and food policy that can be taken to improve their places in the food security index. In this study, an analysis of GFSI for 2017 will be made for Turkey, Romania and Bulgaria. It also includes recommendations on agriculture and food policy of countries for these countries to increase their rankings on the GFSI.

Authors: Artem Victoria , Antoce Arina Oana
Published: September 2018

Cabernet Sauvignon is one of the grape varieties highly suitable for organic cultivation. In the present study, the variety was cultivated in Murfatlar region were both organic and conventional technologies are applied and compared. Also, for each growth system variants with and without 30% cluster thinning were organized. Wines obtained from each variant were compared by the use of an electronic nose. The groups of wines prepared by the same technology were discriminated by the electronic nose in accordance to their volatile profile and on the basis of the discriminating chromatographic peaks determined. The wines produced from grapes conventionally grown were discriminated in two groups by different compounds correlated to the application or not of the cluster thinning operation, while the wines from organic grapes were only slightly separated in groups with or without cluster thinning. However, the wines from organic grapes have shown the highest complexity, as far as the number of discriminant peaks is concerned. Thus, this preliminary study suggests that organic cultivation of grapes may be beneficial for Cabernet Sauvignon wines. The operation of cluster thinning has some effects on the wines made with conventionally grown grapes, but even in this case only 7.6% of the variability in the volatile profile is explained by the cluster thinning. Considering that the grape yield of Cabernet Sauvignon is generally low as compared to other varieties, a further reduction of the grape load may be economically unjustified.

Jerusalem artichoke tubers (Helianthus tuberosus) are distinguished by their protein, minerals (potassium, calcium, magnesium, iron, etc.) and inulin content. Inulin can be used in the diet of diabetics as a substitute of sugar, without having an impact on blood glucose. At the same time, an international study had shown that due to their inulin content, regular consumption of Jerusalem artichoke tubers can help to prevent type 2 diabetes. In this paper are presented the results of the researches performed to achieve a functional ingredient (powder) with high nutritional value by processing of Jerusalem artichoke tubers. Thus, the Jerusalem artichoke tubers (Red Jerusalem artichoke and White Jerusalem artichoke varieties) were subjected to a convective drying process at 50°C, to protect bioactive components (vitamins, phenolic compounds, etc.) to a moisture content that allow their milling and turning them into powder and, at the same time, their stability in terms of quality. The achieved functional ingredient was evaluated sensory, physicchemically and microbiologically. The powder obtained from Jerusalem artichoke tubers is characterized by their inulin-type fructans (51.60... 57.45%), crude fiber (6.85...8.27%), total polyphenols (18.51... 44.03 mg GAE/g), proteins (8.75...9.26%), iron (12.45...13.88 mg/100g), potassium (1905.44...2100.35 mg/100g), calcium (50.21...57.45mg/100g), magnesium (84.55...89.95mg/100g) and phosphorus content (300.12...345.35 mg/100g). At the same time, powder achieved from Jerusalem artichoke tubers has antioxidant potential. Due to its complex biochemical composition, the functional ingredient achieved from Jerusalem artichoke tubers can be used to fortify food and also as a sweetening agent for products destined to diabetics.

Published: September 2018

Starting from the fact that the principles of agro-ecology become fundamental principles for the development of a green economy, especially in the context of current climate change, the effective capitalization of the ecological conditions of an agricultural area is one of the main objectives of agricultural science and practice. Identifying and formulating adaptive technological solutions can guide any producer to capitalize different climate and soil conditions. The sandy soils in Southern Oltenia offer less favourable ecological conditions, and the cultivation of watermelons is now profitable enough for such conditions. Growers are, however, interested in getting the most productive yields, early and profitable, even under the conditions of climate change. The current paper quantifies the grafting of watermelons in the conditions of the sandy soils of Dăbuleni, with poor soil supply, with meteorological drought phenomena and agricultural drought risk, in terms of quality and quantity of production under the climatic conditions in 2015-2017. The results, correlated with the climatic conditions, recommend the cultivation of grafted watermelons, offering the producers in the area a niche of ecological adaptation, ensuring the resistance of plants to abiotic, thermo-hydric stress factors, and improving the resistance to low temperatures, heat and drought.

Published: September 2018

Waste water treatment plants are complex systems consisting of construction, hydro-mechanical, electrical, monitoring and automation equipment. Monitoring activities emphasize that the processes are dynamic; wastewater quality at the entering point of treatment plant varies in a wide range. Treatment technologies adopted must reduce major pollutants; that involves nitrification-denitrification processes and biological and chemical reduction of phosphorus through mechanical-chemical-biological treatment pathways. Increasing the activated sludge concentration in a wastewater treatment plant is an effective method by altering the process dynamics and by reducing the produced sludge volume. There are proposed and discussed in terms of technical and cost efficiency different technological wastewater treatment schemes. In Romania, wastewater treatment plants and sewage systems operating involve processes based on the new systems overrated, there is mandatory to diminish quantities in water supply systems and to exclude improperly working of wastewater pre-treatment stations. Those operations impose technological measures ensuring efficient functioning regardless the service conditions.

Authors: Vrancuta Luciana
Published: September 2018

Soils from agricultural areas are under anthropic pressures, one of the causes being atmospheric deposition of heavy metals. In order to prevent that diffuse pollution affects the soil for long term it is important to reduce the releases of pollutant from air and water. In this paper it was analysed a potential method of chemical remediation applied to the case of an accidental situation of arable soil pollution with heavy metals. The technology of remediation proposed is based on a chemical fixation by adding a reagent into the contaminated soil where it reacts with heavy metals and form insoluble complexes. The organic reagent is one of the best-known and most frequently used in extraction and trace analysis. So, the chemical remediation proposed could decrease the migration of heavy metals in soil and subsequently, in water, plant and other environmental media.

The investigations were aimed to establish the comparative efficiency of four disinfectants (Aquadez, Ecocide S, Virocide and Na OH) used for the disinfection of cattle farm of State Agrarian University of Moldova. According to the classical methodology, the disinfectants have been used in concentrations which were recommended by the producers. Following this, lavages were collected from different supports and equipment of the cattle farm before sparing of the disinfectants and one hour after the contact of the disinfectants with the substrates. In this context samples were taken from places as the feeding space for animals and the rest area, cows’ milking rooms and the milk collection rooms. Afterwards, the samples have been inseminated in laboratory conditions for establishing the afterwards disinfecting effect on the farm. As a result, the microbiological investigation demonstrated that concentrations which were recommended by the producers and double concentrations of disinfectants don’t have satisfactory 100% of the anti-microbial and antifungal effect. For all disinfected places with the mentioned disinfectants colonies of microorganisms grew on nutrient media, especially bacterial forms as Streptococcus, Staphylococcus and microscopic fungal. Following comparisons, Ecocide S 3% and Na OH 3% had a higher efficiency than Aquadez 3%. The after application effect of Aquadez 3% established the presence of Salmonella, E. coli colonies grown on nutrient media as well as, Streptococcus and microscopic fungal.

The purpose of this paper was to compare the composition (weight % of total identified FA) in saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids from 3 food matrices (sunflower oil, palm oil and lard) by 2 different techniques, gas chromatography - mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR). For GC-MS technique, fatty acid methyl esters (FAMEs) identification in the samples was performed by comparison of the retention times (RT) and the mass/charge (m/z) ratio characteristic of each FAME component in the reference standards used (F.A.M.E. Mix C4 - C24 and SRM®2377). FAMEs quantification from food samples was realized by applying correction factors calculated based on reference standards. NMR spectra were recorded on a Bruker Advance 400 MHz spectrometer, operating at 9.4 Tesla corresponding to the resonance frequency of 400.13 MHz for the 1H nucleus. The NMR spectra was recorded directly on the oil without any sample preparation. The difference between the mean values of the fatty acids content determined by GC-MS and NMR was not more than ± 15% for sunflower oil and lard, and ± 6% for palm oil.

Published: September 2018

The decontamination and detoxification of pesticides-contaminated soils is a tough task, due to their persistence and mobility. Camelina sativa is resistant to pests and weeds which affect similar crops mostly due to its unique defence system, attributed tocamalexin and metoxi-camalexin. Considering this, camelina may be cultivated without input of pesticides, but what happens if camelina is cultivated on an already pesticide-contaminated soil? The purpose of the study is to analyze the Camelina sativa potential to concentrate or not the residual pesticides from the soil in its seeds.It was assessed the level of pesticides from the soil on which Camelina sativa-Mădălina variety was cultivated and from the resulted seeds. The quantification was done using a GC-MS-MS equipment. In the soil it was found a total amount of 0.03 mg/kg of pesticides consisting in: o,p-DDE, p,p-DDE, o,p-DDD, o,p-DDT, p,p-DDT, from which 81.4% was p,p-DDE. All the signals registered for camelina seeds were below the LOQ of 0.005mg/kg. Camelina sativa-Mădălina variety can be cultivated on soils contaminated with DDT and its metabolites, minimizing the risk of pesticides translocation.

Published: September 2018

The excessive use of synthetic pesticides for plant pathogens control could cause possible harmful side-effects to humans and animals, environmental pollution, residual toxicity, affects soil characteristics or induce the development of fungal resistance. Alternative ways for fungal contamination control involve natural products, based on microorganisms, many of them being already available for use. The selection and characterization of new biological agents useful for plant pathogens control are permanent goals for plant protection researches. In the last decade, several studies revealed that Streptomyces species are promising biocontrol agents against a wide range of phytopathogenic fungi, including Fusarium spp., one of the most important wheat pathogens. In our study, 60 strains of Streptomyces spp. were isolated from soil or compost and evaluated for in vitro antifungal abilities by dual confrontation method. At least 30% of the isolates presented inhibitory activity against F. culmorum and F. graminearum. The bacterial strains were also tested for their ability to produce various bioactive compounds, possible involved in fungal inhibition. The capacity of some of the bacterial isolates to produce cellulases, amylases, lipases and volatile metabolites was proved. In addition, a new screening method for chitinases production was developed, based on the use of a combination of Congo red and Lugol solutions, which allowed the detection of chitinases in several Streptomyces spp. strains. Moreover, the reduction of the level of some Fusarium mycotoxins was detected by HPTLC analysis. As a conclusion, antagonistic interactions between Streptomyces isolates and fusaria could involve antibiosis, competition and parasitism and suggested that at least some of the selected isolates could be used in obtaining biological control products.

Published: September 2018

The health condition of rolling bearing can directly influence to the efficiency and lifecycle of rotating machinery, thus monitoring and diagnosing the faults of rolling bearing is of great importance. Unfortunately, vibration signals of rolling bearing are usually overwhelmed by external noise, so the fault frequencies of rolling bearing cannot be readily obtained. In this paper, an improved feature extraction method called IMFs_PE, which combines the multivariate empirical mode decomposition with the permutation entropy, is proposed to extract fault frequencies from the noisy bearing vibration signals. First, the raw bearing vibration signals are filtered by an optimal band-pass filter determined by SK to remove the irrelative noise which is not in the same frequency band of fault frequencies. Then the filtered signals are processed by the IMFs_PE to get rid of the relative noise which is in the same frequency band of fault frequencies. Finally, a frequency domain condition indicator FFR(Fault Frequency Ratio), which measures the magnitude of fault frequencies in frequency domain, is calculated to compare the effectiveness of the feature extraction methods. The feature extraction method proposed in this paper has advantages of removing both irrelative noise and relative noise over other feature extraction methods. The effectiveness of the proposed method is validated by simulated and experimental bearing signals. And the results are shown that the proposed method outperforms other state of the art algorithms with regards to fault feature extraction of rolling bearing.
