Solid-state fermentation of chopped sweet sorghum particles to ethanol was studied in static flasks using an ethanol tolerant yeast strain. The influence of various process parameters, such as temperature, yeast cell concentration, and moisture content, on the rate and extent of ethanol fermentation was investigated. Optimal values of these parameters were found to be 35 degrees C, 7 x 10(8) cells/g raw sorghum, and 70% moisture level, respectively.
使用耐乙醇酵母菌株在静态烧瓶中研究了切碎的甜高粱颗粒固态发酵生产乙醇的过程。考察了温度、酵母细胞浓度和水分含量等各种工艺参数对乙醇发酵速率和程度的影响。发现这些参数的最佳值分别为35℃、7×10⁸个细胞/克生高粱和70%的水分含量。
