STRAIN OF MICROORGANISM AZOTOBACTER VINELANDII FOR PREPARING BIOPREPARATION FOR CONTROL OF WHEAT ROOT ROTS AND ENHANCING QUALITY AND YIELD OF HARVEST |
摘要 |
FIELD: agricultural microbiology. ^ SUBSTANCE: the strain Azotobacter vinelandii IB 4 is obtained by analytical selection of natural isolates by method for selection of producers eliciting rather high antagonistic activity with respect to fungal phytopathogens. The strain is deposited in collection of microorganisms of Biology Institution UNTS RAN at number Azotobacter vinelandii IB 4. For preparing the preparation the strain is grown in nitrogen-free nutrient medium at 28-30oC for 60 h under aeration condition up to the titer value 1010 CFU/ml. The strain elicits high nitrogenase activity and ability for producing cytokinins that simulate the growth and development of plants. ^ EFFECT: valuable properties of microorganism strain. ^ 7 tbl, 7 ex |
