Microbial ecology of anaerobic digesters: the key players of anaerobiosis.

open access: yesScientificWorldJournal, 2014
Anaerobic digestion is the method of wastes treatment aimed at a reduction of their hazardous effects on the biosphere. The mutualistic behavior of various anaerobic microorganisms results in the decomposition of complex organic substances into simple, chemically stabilized compounds, mainly methane and CO2. The conversions of complex organic compounds
