新鲜木薯直接转化生产乙醇

Direct Conversion of Fresh Cassava Root to Ethanol

介绍了利用新鲜木薯生产乙醇的新工艺:用真菌α淀粉酶和降粘酶预处理新鲜木薯醪液,后加入颗粒淀粉水解酶STARGENTM进行酵母酒精发酵。该工艺可直接利用新鲜木薯进行酒精发酵;相比传统高温工艺,该发酵新工艺过程中新鲜木薯醪液粘度显著降低,有更多可发酵性糖被利用,并且最终发酵效率显著提高。

In this study, a novel process for directly convert the granular starch of fresh cassava roots to alcohol was descibed. Viscosity reducing enzymes and a fungal alpha amylase are used during pre-treatment stage, followed by adding granular starch hydrolyzing enzymes during yeast fermentation. The results proven that the novel process can decreased viscosity, make more fermentable sugar utilized and increased the fermentation d fermentation efficiency.
