[Promising microbial consortia for producing biofertilizers for rice fields].

Two cyanobacterial cultures from rice paddies of Kyzylorda region, Kazakhstan were isolated and characterized: Anabaena variabilis and Nostoc calsicola. Based on these cultures, new consortia ofcyanobacteria, microalgae and Azotobacter were developed: ZOB-1 (Anabaena variabilis, Chlorella vulgaris, and Azotobacter sp.) and ZBOB-2 (Nostoc calsicola, Chlorella vulgaris, and Azotobacter sp.). High growth rate and photosynthetic activity of microalgae were observed in these consortia. The active consotrium ZOB-1 was selected, which improvd germination and growth of rice plants. ZOB-1 was recommended as a biostimulator and biofertilizer for crops.
