In order to examine anaerobic biodegradations of organic compounds in sewage sediments, a simple method for the determination of H_2,H_2S, CO_2 and CH_4 was established by use of a headspace technique. First, the production of these gaseous metabolites from glucose was studied in anaerobic aquatic sediments. H_2 was transiently detected in the early stage of biodegradation, followed by the production of H_2S. After that, a large amount of CH_4 was produced. Sodium alkyl sulfate (AS) was also degraded to CO_2 and CH_4,but H_2 was not detected in the course of biodegradation. The addition of glucose enhanced the anaerobic degradation of AS. Assuming that the final products were CO_2 and CH_4,the extent of biodegradation of glucose, glucose plus AS and AS was calculated to be 67-80,76-77 and 51-62%, respectively, of the total organic carbon.
