Toxicity effects of organosulfur compounds on anaerobic Microbial metabolism

摘要

Four classes of organosulfur compounds were tested for their effects on anaerobic microbial activity as indicated by rates of lactate degradation, nitrate or sulfate reduction, and methanogenesis. Each class consisted of five to eight chemically related compounds that were added concurrently to anaerobic cultures established with an oily sludge inoculum. Effects on anaerobic activities were evaluated at different amounts of the chemicals and were concentration dependent in all cases.
