摘要
The occurrence and identity of proteolytic bacteria in the anaerobic digestion of raw sewage sludge were investigated. Proteolytic bacteria occurred in numbers of 65 × 106/ml. A high proportion of the isolates (65 per cent) was sporeforming bacteria, and included seven Clostridium species. Cocci comprised 21 per cent of the isolates and consisted mainly of Peptococcus anaerobius and one isolate of Staphylococcus aureus. The remaining isolates were non-sporeforming rod-shaped bacteria and included bifid-like bacteria, Bacteroides species and Eubacterium species. © 1969.
