[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.
