title: [Effect of some electron acceptors on metabolism of methanogenic biotic community].
abstract: The dynamics of redox potential, pH, CH4, H2, CO2, N2 formation under the community development under anaerobic conditions in presence of acceptors of electrons (potassium ferricyanide, molecular oxygen, sodium nitrate and sodium sulphate) has been investigated. It has been established that the optimal value at the redox potential under the development of methanogenic community was created at the expense of microorganisms vital activity. The decrease of methanogenesis under the electron acceptors introduction is connected with the increase of the culture medium redox potential.
