Abstract

Bioconversion of cellulose and xylose is critical for the economically utilization of lignocellulose resources. Cellulose and xylose utilized strain Bacillus cereus Yc-A1 with highly ethanol endurance ability was present. The strain Yc-A1 was identified according to the physiological and phylogenetic characteristics. The maximum carboxymethyl cellulase (CMCase) activity and filterpaperase (FPase) activity reached 0.261 and 0.194 U/ml at 48 and 96 h, respectively. The strain Yc-A1 can use xylose as sole carbon source and its ethanol endurance ability was significantly superior to Pichia stipitis 1960 and Saccharomyces cerevisiae AADY under 10% and 20% ethanol concentration. Ethanol and lactic acid was 0.72 g/L and 8.91 g/L for 72 cultivation analyzed by GC-MS and HPLC-MS, respectively. Bacillus cereus Yc-A1 was inferred to have potential application in cellulose degradation process such as feed industry and paper making industry.
