摘要
Dynamic changes of a microbial community for lignocellulose degradation were explored in details. Community composition and development were investigated by the means of denaturing gradient gel electrophoresis （DGGE）, and results showed that the microbial community was constituted of 14 kinds of bacteria and presented the fluctuation in some degrees with fermentation. Furthmore, the result of cluster analysis of DGGE pattern was accordant with growth curve, and the degradation process was divided into three stages： initial stage （0-12 h）, intermediate stage （24-144 h） and end stage （144-216 h）.
