In this study, rice grass (Spartina spp.), one kind of invasive plant in the coastal areas, was investigated for cellulosic ethanol production. Firstly, the rice grass powder was used as the main carbon source for cellulase fermentation by solid-state fermentation with the strain Trichoderma reesei SEMCC 3.217, then optimal conditions for hydrolyzate with celluase were optimized by orthogonal experimental design and the strain Saccharomyces cerevisiae SEMCC 2.157 was used for ethanol fermentation, after optimized by one-factor-one-time approach, the yield of ethanol could reach 28.1 g/L in 36 h under the optimal conditions.
