THE USE OF MULTISUBSTRATE MIXTURES FOR METHANE BIOSYNTHESIS BY AN ADAPTED COMPLEX OF MICROORGANISMS FOR OBTAINING ORGANIC FERTILIZER

Due to the istabiity of market prices for traditional hydrocarbon energy resources and negative impact of their combustion products on the environment, recently quite rapidly develop technology that provide for, first of all, renewable energy sources. One of the promising areas of alternative energy is bioenergy is a branch of biotechnology that considers organic matter of biomass of various origins (mainly agricultural waste) as a fuel source. Among the main advantages of energy biotechnology, it should be noted the speed and relative ease of recovery of the energy substrate, as well as the fact that it is not alien to the environment, so, even if released in quantities exceeding the permissible ones, this will not lead to irreversible changes in the ecosystem. Excess biomass will quickly be incorporated into biogeochemical cycles, which is the key to minimizing environmental damage. The process of bioconversion of methane from organic substrate compounds (carbohydrates, proteins, nucleic acids, lipids, organic acids, alcohols), which in three stages, is called methanogenesis. This process involves a specific complex bacterial enzyme system, consisting of the following coenzymes: methanofuran, tetrahydro-methanopterin, coenzymes F420 and F430, coenzyme M (CoM), coenzyme B. Using of ways of processing and waste disposal, that based on alternative biological recycling methods of organic pollutants does not always allow to achieve the expected effect, in particular on artificially created ecosystems of animal farms working in a closed mode. Concentration on a small area of a significant amount of biowaste (manure, dung, process runoffs etc.) of the cattle kept in the facilities of live-stock industry, contaminates soils, water bodies and atmospheric air with microorganisms, dust, harmful gases and other decomposition products. Often, it is one of the main factors constrainting on the growth of livestock enterprises and agro-industrial complex (AIC) capacities in general, restraining the economic development of regions specializing in agricultural production. For the first time in the region, study was carried out in order to determine the most efficient way to process miskantus phytomass for the production as target products of methane-containing biogas mixture and organo-mineral fertilizer suitable for use in agriculture and forestry. An economically and ecologically attractive way of utilization of wastes of phyto- and zoogenic origin, which makes it possible significantly reduce anthropogenic pressure on the environment, has been proposed.
