Fig. 6From: Characterization of sulfur oxidizing bacteria related to biogenic sulfuric acid corrosion in sludge digestersPotential microbial sulfur cycle (adapted from Bos and Kuenen [38]) in a digester system. Predominant anaerobic conditions are marked with a continuous line; potential aerobic reactions are shown as dashed lines. A few organisms found in this study are providedBack to article page
