The problem is solved in research on the development of biotechnology for the production of biofuel II generation (methane-containing gas mixture), the use of spent digestate as an organo-mineral fertilizer for the needs of agriculture and forestry. The physicochemical aspects of the process of biomethanogenesis have been studied and discovered, a sequence of biochemical processes has been established in the production of biogas and their details have been clarified. The species composition of the initial substrate for biomethanogenesis and its microbiological characteristics are determined. The traditional biotechnology for obtaining biogas has been improved due to the use of a new substrate – the excess organic matter of hydrobionts from «blooming» spots, which is based on the biomass of cyanobacteria. The chemical composition of biogas samples of different origin is determined and a comparative analysis of their physical properties is made. A new ecologically safe technological process has been created, which ensures the rational use of natural resources (excess biomass of cyanobacteria). The expediency of using the excessive mass of cyanobacteria, which is formed during periods of «blooming» of reservoirs, is justified as an energy source. The process of biomethanogenesis is modeled in laboratory conditions. Ecological and economic importance of cyanobacteria and prospects for the effective use of their bimass have been determined, and the scientific basis of safe technology for processing biomass of cyanobacteria has been substantiated.
