摘要：In order to examine anaerobic biodegradations of organic compounds in sewage sediments, a simple method for the determination of H₂, H₂S, CO₂ and CH₄ was established by use of a headspace technique. First, the production of these gaseous metabolites from glucose was studied in anaerobic aquatic sediments. H₂ was transiently detected in the early stage of biodegradation, followed by the production of H₂S. After that, a large amount of CH₄ was produced. Sodium alkyl sulfate (AS) was also degraded to CO₂ and CH₄, but H₂ was not detected in the course of biodegradation. The addition of glucose enhanced the anaerobic degradation of AS. Assuming that the final products were CO₂ and CH₄, 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.
