Abstract

Abstract

Endoglucanase, exoglucanase and cellobiase activities of ten cellulose degradation isolates from piggery sludge and manure were analyzed.A complex microbial system was constructed by five bacteria named as LCB03, LCB12, LCB52, LCD12 and LCD51 respectively with different cellobiase activities from these isolates.Tested from the perspective of physiology and microchemistry as well as molecular level, these five bacteria were identified as Pseudomonas citronellolis, Stenotrophomonas maltophilia, Pseudomonas aeruginosa, Pseudomonas aeruginosa and Flavobacterium mizutaii, respectively.So far, there are few papers on cellulose degradation using S.maltophilia and F.mizutaii.Each of the five bacteria could produce different types of cellobiase that co-catalyze degrading natural cellulose effectively, and the microbial system therefore has great potential in cellulose-related pollution control and waste utilization.
