Abstract

Sulfide (S^2-) and nitric oxide (NO) can be formed in anaerobic digester if nitrate and sulfate were presented in the influent streams. This study noted by 4,5-diaminofluorescein diacetate (DAF-2DA) staining and confocal laser scanning microscopy (CLSM) the presence of nitrososulfides (SNO) complex in the S^2-+NO-amended methanogenic sludge. Kinetic analysis suggested two-step kinetics involving chemical equilibrium between S^2-, NO and SNO as step 1 and the slow conversion from SNO to N₂O as step 2. The SNO complex was claimed to have higher inhibition effect than S^2- or NO alone on the methangenic activities. Comments were made on the role of SNO complex for the interactions between sulfur, nitrogen and carbon metabolisms in anaerobic digestion. © 2013 Elsevier Ltd.
