| 摘 要： | 油菜秸秆含有大量木质纤维素,该类物质结构稳定,不易降解,限制了其工业化应用.通过对10株包括细菌、酵母菌和白腐真菌的菌株产酶能力和特性进行比较,并进行共同培养试验,筛选出5株可共同生长的木质纤维素降解菌BS09、BL、PC、TS和KS.通过对这5个菌株单独发酵降解油菜秸秆的能力考察,结果表明:PC对木质纤维素的降解能力...

| 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. |
