CURRENT STATUS AND POTENTIAL OF BIOTECHNOLOGICAL APPROACHES FOR RICE BLAST DISEASE IN THE RICE CULTIVATION TECHNOLOGY

abstract 1011407066 issue 101 pp. 1045 – 1055 30.09.2014 ru 2543
Rice blast caused by Pyricularia oryzae is a major disease affecting rice production grown in upland and wetland rice. Application of biotechnological approach to protect against the disease may be an alternative strategy to chemical control

DEVELOPMENT OF A FUNCTIONAL FEED ADDITIVE

abstract 1151601040 issue 115 pp. 643 – 664 27.01.2016 ru 344
The new feed additives for animals based on milk whey, enriched with sprouting wheat, barley, maize grains and lactic-acid bacterium have been presented in this article. This study explores the possibility of combining the prebiotics ability of milk whey and sprouting grains with feed probiotic attributes of microbe to enhance gut health of animals and digestibility of the feed. Twelve variants of products were tested in the study using the microbial and physical-chemical approaches. All the assays showed high count of microorganism and high content of reducing sugar. The results of investigation indicate that selected feed additive show high quality. An additional point is that it contains useful organic acids (lactic, acetic and propionic acids) and 2,1×109 colony-forming unit of probiotics microorganism that hold the concentration for 4 months. There are not yeast, must, coliform bacteria and Staphylococcus aureus in the developed functional feed product. It contributes to the normalization of the microflora of the gastrointestinal tract of animal, suppression of conditionally pathogenic and putrefactive microflora. The elaborated feed component will help to provide combined feed companies with accessible high-quality raw material

DEVELOPMENT OF PROTEIN ENZYME FEED ADDITIVE FOR POULTRY FARMING

abstract 1121508136 issue 112 pp. 1870 – 1886 30.10.2015 ru 861
The research work was conducted at the Research Laboratory of Biotechnology, Biochemistry, Biophysics Department of Kuban State Agrarian University. The main purpose of this study was to select the most productive type of fungus of a genus of Trichoderma and optimal nutrient medium on basis of a waste of reprocessing of soy for acquire of protein enzyme feed supplement. For selection of a fungus of a genus Trichoderma used 3 types: Trichoderma viride, Trichoderma lignorum, and Trichoderma harsianum. We used 3 types of nutrient media as a carrier for micromycete, which were based on soy okara and the additional sources of reprocessing of raw plant material – husk of a sunflower, husk of wheat (bran) and husk of rice. The results demonstrated the benefits of using the nutrient medium based on soy okara forms and husk of a sunflower fungus to enhance Trichoderma lignorum production

FEATURES OF THE CULTIVATION OF PROPIONIBACTERIUM SHERMANII STRAIN

abstract 1141510088 issue 114 pp. 1159 – 1172 30.12.2015 ru 1069
We have presented materials about nutrient media for growing and industrial the cultivation of Propionibacterium shermanii: Trypticase Yeast Extract Glucose Medium, the culture medium Ellinger and ATCC Medium 33. We have studied pH change and its impact on the biomass accumulation of propionic acid microorganisms. We have also defined the best time of cultivation

OPTIMIZATION OF COMPOSITION CULTURE MEDIA, TECHNIQUE OF CONCENTRATING AND FREEZE DRYING CONDITIONS FOR CELL OF LACTOBACILLUS ACIDOPHILUS

abstract 1021408042 issue 102 pp. 681 – 691 31.10.2014 ru 1053
This study has investigated the relationship between culture media, technique of concentrating and freeze drying conditions for the cells of Lactobacillus aci-dophilus. The study has demonstrated that milk whey tomato juice-enriched medium has the high-growth properties. This medium allows ensuring high freeze drying survival of Lactobacillus acidophilus
