NSC-7 could degrade 73.6% of rice straw within 14 d. 10 kinds of material were detected in volatile products by gas chromatography mass spectrometry, and they were 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 30 min, and resume its degrading ability after subcultured 2 times after 105℃ of high temperature treating for 30 min in autoclave.
