Abstract  

The rapeseed straw contains large quantities of lignocelluloses and its structure is stable and hardly degraded. By comparing the enzyme produced ability and characteristic in ten strains microbe, including bacteria, yeast and white rot fungi, and co-culture testing, the five strains symbiotic microbe, including BS09、BL、PC、TS and KS,were screened out. Investigating the rapeseed straw degrading ability of the five strains, the results showed that PC had a strong degrading ability for lignocelluloses, that degradation rate of lignin, cellulose and hemicellulose was 16.5%, 22.7% and 20.3% respectively. The BS09 and BL had a significant effect in degrading cellulose and hemicellulose, and degradation rate of cellulose and hemicellulose reached 19.5%,15.0%, 16.0% and 22.1% respectively.
