title: Simulation of constituent processes of anaerobic degradation of organic matter by the "methane" model.
abstract: The model of anaerobic digestion described earlier by the authors was used for analysis of the different phases of the process. It was shown that at the glucose conversion a coexistence of hydrogen-producing acidogenic bacteria and hydrogen-utilizing non-methanogenic bacteria causes a hydrogen partial pressure decrease at an increase of solids retention time (i), the intensity of the negative feed-back effect in sulfate-reduction through hydrogen sulfide formation is regulated by the pH level during an oscillation dynamics in acetate/sulfate system (ii), under the toxicity influence the processes of methanogenesis and acetogenesis together with hydrolysis may be rate-limiting steps in the anaerobic system with particulate substrate degradation (iii).
