| Abstract: | Summary Cellulolytic enzymes from a laboratory anaerobic digester fed municipal solid waste were examined with respect to pH and temperature. The pH optimum was pH 6.6, considerably lower than the pH range in which digesters are normally operated (pH 7.2–7.6). The optimum temperature was between 50 and 60°C, rather than the 35–37°C range in which most digesters are controlled. |
