NSC-7 could degrade 73.6％of rice straw within 14d. 10 material were detected in volatile products by gas chromatography mass spectrometry,and it was mainly acetic acid, glycerol, butyric acid, and propanoic acid. NSC-7 could retain stable degrading ability and high cellulase activity after preserved in -80 and freeze℃-drying for four years. It could remain its degrading ability after 90 of high ℃temperature treating for 30min, and resume its degrading ability after subcultured 2 times after 105 ℃of high temperature treating for 30min in autoclave.
