摘要：
The exploded bast, branch and stem of cotton stalk were degraded by alkalophilic Bacillus NT-19, with weight losses of 24%, 20% and 14%, respectively, after 14 d. Compared with a white-rot fungus (Phanerochaete chrysosporium), Bacillus NT-19 preferentially degraded the non-cellulose components of cotton stem. The relative degree of crystallinity of bast fibers decreased by 8% and the middle lamella was partially removed from the fiber bundle by the Bacillus.
