Disproportion of organic wastes into biogas by means of a tow-stage, thermophilic fermentation process. Final report. Disproportionierung organischer Abfaelle zu Biogas mit Hilfe eines zweistufigen, thermophilen Gaerverfahrens. Abschlussbericht

Abstract

The work carried through in the period of report January 1 - December 31, 1985 comprised the following: Impacts of the composition of the synthetic substrate on the space-and-time-related yield of microbial methane production, and further experiments for the characterization of screened methanogenic bacteria. Screening for co-cultures decomposing propionic acid was taken up, in order to elucidate problems encountered in tracing the decomposition paths of propionic acid in mixed cultures. Comparative experiments were conducted with different reactor configurations for obtaining methane from cow and bullock liquid manures; these provided new results in comparison with data published, as far as gas yield and gas productivity as a function of space load are concerned.
