In this experiment, a strain of Bacillus lincheniformis was isolated and identified, which was used to ferment celluloserich substrate. The effects were analyzed. The experimental results showed that Bacillus lincheniformis had the capacity to degrade cellulose(32.8% was degraded) and less capacity to degrade hemicellulose(7.9% was degraded), which could not degrade ligin. The total protein contents in the products fermented by Bacillus lincheniformis with cellulose-rich substrate riched by 11.6%, compared with the fermented products with no cellulose-rich substrate, furthermore, the contents of Met, Lys and Leu riched by 14%, 17.5% and 4.1%, respectively. These results showed that Bacillus lincheniformis had the ability to degrade cellulose and it provided experimental data for further utilization.展开更多
