Abstract
Microorganisms isolated from natural sources that have antagonistic properties are the objects of the research in this paper. The main objective of the study was to screen and characterize the antagonistic properties of microorganisms isolated from natural sources in connection with the creation of new pharmaceutical substances. Methods of cultivating strains of microorganisms, chromatographic methods, spectrometric, electrophoretic methods of analysis, and methods of cryopreservation of accumulative cultures were applied. In the course of the experiment, nutrient media for cultivating strains of antagonist microorganisms were optimized, and the physiological and biochemical properties of lactic acid bacteria and other antagonist microorganisms were studied. It is proved that lactic acid bacteria and other antagonist microorganisms show antimicrobial properties on a solid medium. The antibiotic resistance of lactic acid bacteria and other antagonist microorganisms was studied, the biocompatibility of lactic acid bacteria and other antagonist microorganisms was proved. During the investigation, the antibacterial properties of the isolated peptide fractions were determined, the fungicidal properties of the isolated peptide fractions were established, and low-molecular protein compounds with antibacterial and antifungicidal activity were identified; the toxicity indicators of identified bacteriocins and fungicides were studied in vitro. The novelty of this work consists in the development of scientifically based approaches to screening and characterization of antagonistic properties of microorganisms isolated from natural sources, as well as to the cultivation of antagonist microorganisms in connection with the creation of new pharmaceutical substances of antimicrobial action.

Published: December 2020

Abstract
The development and use of a practical method for producing antioxidants (less energy-consuming and more economically viable) is relevant and contributes to the expansion of the market of “functional” products and the receipt of new dietary supplements. An experimental model of a laboratory low-frequency vibration extractor was developed to intensify the technological process of extraction from plant material containing ALS. Some technological parameters of the anthocyanins extraction process have been determined: raw material / extractant ratio, % extractant concentration, as well as some design parameters of a pilot plant (vibration extractor). The possibility of obtaining anthocyanins from the waste of the fruit and berry industry with a high percentage yield of biologically active substances has been experimentally shown.

Authors: Petrova A S 
Published: December 2020

Abstract
The need to introduce innovative technologies in the food industry is a requirement of the time. What previously seemed completely incompatible is now becoming a close and complementary unity of knowledge due to the emergence of convergent technologies. In the course of a specific study, it was shown that the synthesis of biotechnology, which provides methods for working with living organisms (in our case, yeast) and nanotechnology, which forms the basis of the scientific and technological revolution, will radically change food technology. According to experts, about 85% of food production is somehow related to the use of microbiological processes. Modern food biotechnology is associated with increasing requirements for the intensification of technological processes. Acceleration of food production processes without deterioration of their quality characteristics is an extremely relevant area of research. The use of biotechnology to develop a new method of intensifying the fermentation process will provide a solution to one of the key social problems – accelerating the progress of the food industry. The relevance of research conducted in this direction is also confirmed by the fact that the use of new technologies based on innovations in various fields of knowledge and being their synthesis leads to an increase in economic and, as a consequence, social welfare. As a result of the study, it was found that the use of colloidal silver for water treatment during a series of experiments resulted in an increase in the lifting force of yeast.

Published: December 2020

Abstract
Hydrostatic extrusion implemented in the fluid friction regime creates the most favorable stress state of the billet in the deformation zone, which ensures its improved mechanical properties: increased yield strength and strength with a high margin of plasticity, and greater uniformity. In order to implement the fluid friction regime throughout the entire process, a hydrostatic extrusion scheme with an uncompressed shank is proposed with the working chamber structurally divided into two cavities – radial and axial ones, and process design schemes are developed. The paper presents the results of calculation of pressure distribution along the shank for this scheme with regard to non-isothermal fluid flow in a thin annular gap, their graphical interpretation (pressure distribution diagrams along the shank at pressure drops ΔP), and data analysis. The pressure calculation results obtained can be used to determine the gap along the shank with regard to elastic deformation of the working chamber walls and the shank, and to adjust the calculation of other process parameters.

Abstract
Turkey meat is one of the most valuable poultry products. The purpose of the study is to compare the chemical composition of meat of turkeys of different crosses in the conditions of the South Urals. For the experiment, four groups of turkey poults were chosen: medium cross Broad Breasted White; heavy cross Broad Breasted White; medium cross Hybrid Converter; heavy cross Hybrid Converter. It was found that the cross Hybrid turkey meat is qualitatively superior to the meat of turkeys of different Broad Breasted White crosses in terms of protein content in red and white meat, as well as in the lower fat content. The energy value of Broad Breasted White turkey meat was found to be insignificantly higher due to different fat content, except for the energy value of white meat from medium cross turkeys.

Published: December 2020

Abstract
The hue and color intensity are referred to optical properties of soft drinks made from fruit and berry raw materials that are crucial for control of their quality and identification. In addition, a natural color of raw materials is attractive for consumers since it provides a more appealing natural appearance to the drink. Sea buckthorn drinks are prone to browning during storage due to the specific chemical composition of berries, which necessitates the control of their optical properties. The study aimed to investigate optical properties of different groups of sea buckthorn drinks during storage, namely clarified juice and dry wine material made from sea buckthorn of the Chuiskaya variety, and to establish the possibility of using some calculated parameters that characterize the drink color in techno-chemical control practices. Optical properties of drink samples were determined with a UV-1800 spectrophotometer, and the values obtained were used to calculate the parameters of intensity, hue, and yellowness. It is shown that physical methods can be used to control optical properties of sea buckthorn drinks in order to objectively assess the color as one of the basic organoleptic parameters of drink quality. It is established that the results of optical analysis are consistent with visual assessment of the sea buckthorn drink samples during storage, which opens up prospects for implementation of this research method in the laboratories of enterprises involved in processing of sea buckthorn to produce various groups of drinks.

Authors: Selionova M I , Plakhtyukova V R 
Published: December 2020

Abstract
The improvement of beef cattle is associated with the use of molecular genetic testing for genes associated with signs of meat productivity. The article presents the results of studies of gene polymorphism of calpain (CAPN1) and growth hormone (GH) in different sex and age groups of the Kazakh white-headed breed and its effect on the dynamics of live weight of young animals. It was found that polymorphism of the CAPN1 and GH genes is represented by three genotypes of CC, CG, GG and VV, LV, LL, respectively. The most common in the CAPN1 gene are the G allele and the GG genotype, the frequency of which ranged between 0.83-0.89 and 0.72-0.81, in the GH gene, the L allele and the LL genotype, the occurrence of which, respectively, was within 0.60-0.81 and 0.51-0.66. The carriers of the desired alleles, both in the homozygous and heterozygous state, were insignificant: in the CAPN1 gene, in the range of 0.03-0.22, in the GH gene, 0.03-0.31. In the CAPN1 gene, a lack of heterozygotes was observed in all groups, while in repair young animals it was higher than in animals of the parent herd. In the GH gene, a slight excess of heterozygotes was found in manufacturing bulls and repair bulls, while among cows and repair heifers they were deficient. Significant superiority in live weight at 8 and 12 months of age of gobies and heifers carriers of genotypes CAPN1CC and GHVV over peers CAPN1GG and GHLL was established by an average of 13.7 (P <0.05) and 6.8 %%; 12.1 (P <0.05) and 6.7 %%.
Development of a biological method to control the poisonous weed plant heracleum sosnowskyi manden
Authors: Semchuk N N , Balun O V 
Published: December 2020

Abstract
The level of aggression of invasive species in some cases is so high that natural plant communities undergo significant changes in vertical and horizontal structure of phytocoenosis. Often, the species composition of the ecosystem can also greatly decrease. For active introduction into historically established plant communities, a new species must have a special norm of genotype response, which in one or more parameters exceeds that of native species. This gives it an advantage that allows it to expand its range and dominate. The phenomenon with the species Heracleum sosnowskyi Manden is also different in that the plant causes dangerous diseases in humans. It is no coincidence that this weed has been controlled by the government in recent years.
Evaluation of sires with respect to production of their daughters and proportion of holstein blood
Authors: Semkiv M V 
Published: December 2020

Abstract
One of the best domestic dairy breeds is black-motley breed. At the same time, the Holstein breed has been one of the most highly productive for a long time. All world records for milk production were set by the Holstein breed. Moreover, it is very demanding in terms of management. In current conditions of the dairy cattle development, the semen of Holstein sires is still being used to increase the milk production of black-motley cows. Until today, there is no consensus on the optimal proportion of blood of the improving breed. The paper analyzes and evaluates the production of the daughters of sires depending on the proportion of blood of the Holstein breed. As a result, it was found that sires of Holstein lines have a positive effect on the production qualities of the black-motley breed, which ultimately leads to an increase in milk production. At the same time, in order to further improve the breeding and productive qualities of cows in herds, it is necessary to use sires assessed by the quality of the offspring, which are improvers in terms of milk yield and milk fat content. Consistent implementation of all technological solutions should be a fundamental factor in realization of the genetic potential.

Published: December 2020

Abstract
Horticulture as a branch of agriculture was developed as a means of increasing the crop productivity and economic feasibility of agricultural production. Advancement of various agricultural technologies, such as chemical and biological growth promoting substances and application of fertilizers, pesticides, substances that protect plants from diseases, causes ecological imbalance. For this reason, it is essential to perform the task of developing new technological methods that make it possible to unlock genetic potential of plants and get higher yields avoiding any environmental impact. Laser irradiation is one of such methods. Pre-sowing seed treatment with low-intensity red spectrum laser irradiation positively affects the growth and development of plants. This research paper conveys the study of the effect of red spectrum laser irradiation that allows one to irradiate mustard and radish seeds with continuous light using left and right rotating laser beam sweep in order to activate chemical matter with L- and D-conformations in plants. The effect of this treatment on germination capacity and energy was studied as well.

Published: December 2020

Abstract
The objects of this research are microplants of 3 potato varieties acquired from the lab of Novgorod regional branch of Federal State Budgetary Institution “Russian agricultural center” in order to create a nursery. The research goal is to study the characteristics of growth and development of potato varieties, to gain healthy starter material in Novgorod region and to use it in seed production. In the course of this research, phenological observations of growth and development of potato microplants were performed, the effect of the application of “Agrovit-Kor” fertilizer on growth and development of potato microplants was studied and a field nursery of elite and super-elite class potatoes was created. As a result of the study of crops productivity and harvest indexes in D. P. Pavlyuk farm, Aurora potato variety was singled out. Productivity of its plants was 319.7 gram per one bush and its harvest index is 1:15. Impala potato variety stood out in the course of the same study in N. S. Kolesnikov farm - productivity of its plants was 220.9 gram per one bush and its harvest index was 1:12. Red Scarlett variety gives constant yields of potato minitubers. We recommend to perform health-improvement of Red Scarlett potato variety, increase the growing space of microplants, adjust air conditions in greenhouses, improve the drip irrigation system and if possible, install an automatic control system; add growth promoting substances to soil mixture in order to enhance the resistance of microplants to the air conditions in greenhouses; to plant out microplants in the first decade of June for better survivability and protection from late spring frosts and temporary drought that might come due to a sharp rise of mean daily temperatures. We recommend to use “Agrovit-Kor” fertilizer and add calculated doses of humates and growth promoting substances to soil mixtures in order to improve survivability, to encourage an even formation of plants habitus and to increase the harvest index of potato minitubers. In order to improve water conditions, it is required to install a drop irrigation system, expand the range of usage of middle-early potato varieties of Russian (“Eurasia”) and Belarusian (“Yanka”, “Skarb”) selection.

Abstract
The condition of the vegetation cover in Moscow was estimated using the NDVI vegetation index. To construct synthetic images, Landsat 5, 7, and 8 multispectral satellite images taken during the active vegetation period from 1999 to 2019 were used. Index indicators are calculated for pine forests located in protected areas, in urban parks among high-rise buildings and inside private low-rise building districts. The results showed differences in the NDVI values between these three types of birch forests, however, temporal trends show similar dynamics of changes in the physiological state of trees over the studied period.
