Abstract
Two Clostridium thermocellum strains were improved for ethanol tolerance, to 5% (v/v), by gradual adaptation and mutation. The best mutant gave an ethanol yield of 0.37 g/g substrate, with a growth yield 1.5 times more than its parent. Accumulation of acids and reducing sugars by the mutant strain with 5% (v/v) ethanol was lower than that of the parent strain with 1.5% (v/v) ethanol.
摘要
两种嗜热梭菌菌株通过逐步适应和突变得到了乙醇耐受性的提高，达到 5%（v/v）。最佳突变株的乙醇产率为 0.37 g/g 基质，比其亲本的生长产率高 1.5 倍。在 5%（v/v）乙醇下，突变株的酸和还原糖积累低于在 1.5%（v/v）乙醇下的亲本菌株。
