ABSTRACT

Results of the investigation confirmed a possibility of forming artificial microbial consortia based on the blue-green algae (cyanobacteria) Nostoc paludosum. Such associations maintained their structure and activity drying long-term cultivation on the liquid mineral medium in a collection under stable conditions. Compatibility of blue-green algae with Rhizobium leguminosarum, R. galegae, Agrobacterium radiobacter, Pseudomonas fluorescens, and Azospirillum lipoferum is discussed. We have demonstrated the stability of artificial double and triple consortia and arrangement of the partners in them without Azospirilla. The comparison of the seed treatment of Galega orientalis with R. galegae only and seed treatment by consortia Nostoc paludosum + R. galegae showed significant advantages of the consortia inoculation. Prospects of using artificial algal-bacterial associations in agricultural biotechnology are discussed.
