MODELING OF CULTIVATION ON PRODUCTIVITY LACTIC ACID PRODUCER LACTOCOCCUS LACTIS CH5
Description
The equations for evaluation of the stationary state of lactic acid microbiological synthesis have been received. The kinetic dependencies for specific biomass growth rate, consumption of the substrate are given. The particular qualities of growth of homofermentative lactic acid producer Lactococcus lactis CH5 depending on the composition nutrient medium: glucose and yeast autolysate concentration are examined. The influence of the method of cultivation on the productivity and the speed of the lactis acid synthesis are analyzed

THE RESEARCHES IN THE FLOODPLAIN OF THE STEEPE ZONE OF THE KRASNODAR REGION
Description
The article presents the violation of water protection zones. The change in soil fertility. Transparency is linked to the nature of the coating beaches and surface destruction. Surface runoff depends on the vegetation cover. The destruction of vegetation (deforestation, excessive grazing, fire), incorrect plowing surface (along the slope) and tillage farming without following the rules lead to increased erosion, local soil erosion, gully erosion and the rise to an increase in turbidity of rivers. Environmental effectiveness of forest plantations. Prevention of pollution and siltation of river. Improving the sanitary condition of the territory

DEVELOPING OF THE METHODOLOGY FOR THE IDENTIFICATION OF PICEA ABIES L. CLONES BY USING ISSR MARKERS
Description
The technology for the identification of Picea abies L. clones by using ISSR markers was developed. 9 ISSR primers ((GA)9T; (AC)8C; (CA)6RY; (CA)6RG; (CA)6(GT); (CA)6(AC); (AG)8T; (GA)8С и (AG)8YT) were recommended to use for genotypes detection. The selected primers have shown the high level of polymorphism. A total of 172 amplified fragments were found by the selected primers and 149 (86.6%) of them were polymorphic

Description
Based on the information stored in the system of database management, biodiversity indices with special accent on measures of species richness are comparatively studied for Carabid beetles in various areas of the East Caucasus. Biodiversity indices are shown to be dependent on sampling or collecting techniques, sample size, geographic localization and its area

Description
The historical and geographical information of peste des petits ruminants and the characteristics of its agent are given, also some epizootological features of the infection are described, and PPR specific prophylaxis and control measures are discussed
-
Description
We studied the resistance of the eight strains of oil-destructive actinomycetes, isolated from the oil-contaminated ecosystems to heavy metal salts when cultivatiwng with different carbon sources. Furthermore we researched feasibility to use those microorganisms for bioremediation of oil- contaminated sites with high level of heavy metals
-
Description
This article is devoted to the biotechnological properties of the oil-degrading strain Rhodococcus erythropolis B2, which allow us to use microorganism B2 as a base of biopreparation: hydrocarbon- destructive potential, growth characteristics on the different media, producing phytohormones and biosurfactants, adhesive and floatation activity, and also laboratory and field tests

USAGE OF THE BACTERIAL PREPARATION “DESTROIL” FOR DESTRUCTION OIL POLLUTION IN FRESH WATER
Description
The researches of degradation of oil products in fresh-water reservoirs at the expense of the activity of petrooxidizing bacteria of Acinetobacter speivs SN-2 are carried out. The decrease in the content of oil products in 25 days prior to maximum concentration limit (0,05 mg/l) and the increase in concentration of oxygen in the reservoir are defined
