以甘蔗渣为原料，研究了加压微波水热无机盐预处理、耐盐纤维素酶（Meicelase）和耐盐酵母菌（Saccharomycescleae BA 11）同步糖化发酵（SSF）的高效乙醇生产工艺。以加压微波处理后的甘蔗渣为原料，添加不同的无机盐，进行成分分析、酶法糖化和酒精发酵。在200 °C的处理温度下使用2wt%MgCl 2进行5分钟的处理时间的加压微波处理，随后进行SSF而不进行无机盐的洗涤处理，提供了最大的葡萄糖和乙醇产率，即0.392和0.18g/g原料，分别对应于99和90%的糖化和乙醇转化率。
A novel biomass pretreatment method, i.e. pressurized microwave hydrothermal treatment with inorganic salts, and the simultaneous saccharification and fermentation (SSF) using salt-tolerant cellulase, i.e. Meicelase, and salt-tolerant yeast, i.e.Saccharomyces cerevisiaeBA11, were studied for the efficient ethanol production from sugarcane bagasse. The component analysis, enzymatic saccharification, and alcohol fermentation were carried out using pressurized microwave treated sugarcane bagasse with various inorganic salts. The pressurized microwave treatment using 2 wt% MgCl2at a treatment temperature of 200 °C for a treatment time of 5 min followed by SSF without washing treatment of inorganic salts provided the maximum glucose and ethanol yields, i.e. 0.392 and 0.18 g/g-raw material, those corresponded to 99 and 90% of saccharification and ethanol conversion ratios, respectively.
