Abstract: In order to investigate degradation ability, degradation products and changes of munities of a
normal temperature lignocellulose-degrading microflora. The munity could pose % of rice straw
gross weight within six days in room temperature. More than ten kinds of volatile products were detected by GC-MS in the
fermented broth. For analyzing plexity of the munities from the broth, Denaturing Gradient Gel
Electrophoresis (DGGE) were used to identify position diversity and dynamic changes, the DGGE profiles indicated
that the anism changed lots in different period, and the ic tree derived from 16S rDNA sequence
indicated that the munity have the abundant diversity.
Key words: Lignocellulose-Degradation; munity; degradation products; Composition diversity
Ⅰ. INTRODUCTION Ⅱ.MATERIALS AND METHODS
Straw was the most important agricultural waste after A. Materials
harvesting, and also the main origin of anic matter.
Straw was submerged in % NaOH for 24 h, then
Because lignocellulose is the primary product of the straw and
washed with
