Impact of a Number of Factors on Physiological and Biochemical Activity of Strains – Components of Azogran, a Complex Bacterial Preparation.

The use of microbial preparations in plant-growing can be due to the correction of biological processes in agroecosystems and stimulates growth and development of plants. The efficiency of this process is dependent on biotic and abiotic factors, however their influence on introduction microorganisms in phytosphere is insufficiently studied. The article summarizes some results of recent studies, related to the impact of a number of environmental factors on physiological and biochemical activity of nitrogen-fixing bacteria Azotobacter vinelandii IMV B-7076 and phosphate-mobilizing strain Bacillus subtilis IMV B-7023 – components of Azogran, a complex bacterial preparation for plant growing.

[Peculiazities Growth of Bacteria Azotobacter vinelandii IMV V-7076 and Bacillus subtilis IMV V-23 in Pure and Mixed Cultures at Submerged Cultivation].

The features of the growth of Azotobacter vinelandii IMV V-7076 and Bacillus subtilis IMV V-7023 in optimized environments in single and mixed culture at deep cultivation to simulate the accumulation stage (capacity) biomass biotechnology creation of complex bacterial preparation for crop production. When growing Bacillus subtilis IMV B-7023 in monoculture specific growth rate of the bacteria was higher than that of Azotobacter vinelandii IMV B-7076. Therefore, by cultivating a mixed culture medium in the fermenter was inoculated with the bacterial suspension A.

Influence of Silica Nanoparticles on Antioxidant Potential of Bacillus subtilis IMV B-7023.

It was found that if introduced into a nutrient medium of 0.05-1 g/L nano-SiO2, the oxidant activity (OA) of the culture medium (CM) of bacilli increased by 43.2-60.

It is shown that the bacteria Bacillus subtilis B-7023 IMV produce indole-3-acetic acid and amino acids in the liquid medium Knoop. Processing cucumber seed suspension containing 10(7) cfu/ml as bacilli, and Azotobacter vinelandii IMV V-7076, resulted in a decrease in the length of the roots of plants. Reduction of bacterial load bacilli to 10(6) cfu/ml followed by reduction of indole-3-acetic acid in the medium, and to an increase in the length of roots, shoots and total plant mass.

The influence of dispersed saponite on growth activity of Bacillus subtilis IMV B-7023 and its streptomycin resistant mutant has been shown. The effectiveness of this process depends on the content of dispersed material and phosphate in the medium. It has been found that when B.
