| Recently, there has been the problem of water enrichment with nutrients as a result of the anthropogenic activity, in particular the increase in the content of available forms of nitrogen, phosphorus, and carbon, which contributes to the growth of bioproducts of algae and other mass forms of aquatic organisms. This phenomenon is known as “cultural eutrophication.” One of the effective measures to counteract the “blooming” of natural reservoirs can be the timely removal of a significant part of the excess biomass of cyanobacteria (or blue-green algae – BGA) from the water with its further effective use in the economy. The issue solved in the paper is the development of non-waste biotechnology for receiving a second-generation biofuel (gas mixture containing methane) of a new renewable substrate – biomass of cyanobacteriae and further application of the digestate as organic and mineral fertilizer for the purposes of agriculture and forestry. The physical and chemical aspects of bio-methanogenesis were disclosed and researched; the sequence of the bio-chemical reactions in the production of biogas from blue-green algae was established and their features were determined. The species composition of the initial substrate for bio-methanogenesis and its microbiological properties were determined. The chemical composition of the biogas samples of different origin has been established and a comparative analysis of their physical properties was carried out. The traditional biotechnology of biogas production was improved through the use of a new substrate. A new environmentally safe technological process, which ensures a rational use of natural resources, was developed. The practicability of using a cyanobacteria biomass that appears during the “bloom” of water reservoirs was substantiated. The ecological and economic importance of blue-green algae and prospects of their biomass use were determined, and the scientific foundations for safe cyanobacteria biomass processing were substantiated. The virtual complex of technological process for the production of methane and fertilizer from mono- and multisubstrates based on the cyanobacteria biomass and other hydrobionts mass forms, as well as traditional sources of organic matters (like food industry and agricultural wastes, leaf litter from green zones of populated areas, activated sludge of waste treatment facilities, etc.), was developed. |
