Abstract

H2 is a central metabolite and a regulator in the methanogene microbial community (1). The example of methane fermentation of cattle manure allowed us to demonstrate that hydrogen concentration in the gas phase under the balanced community activities does not exceed threshold levels for H2-utilizing methanogenic bacteria: 10 ppm for mesophillous and 40–60 ppm for thermophillous ones (2). There was suggested the possibility of applying hydrogen concentration as a control parameter (3).The aim of the work was to examine the impact of some physico-chemical factors on the change of hydrogen concentration in the produced biogas under the thermophilic cattle manure fermentation. The experiments were conducted under the conditions of periodical cultivation. Hydrogen and methane concentrations in the gas phase were determined on the chromatograph with a solid electrolytic cell (4).
