膜生物反应器封闭循环发酵系统对野生酵母的驯化
Acclimatization of wild yeast through the close-circulating fermentation system with a PDMS membrane bioreactor
摘要
Abstract
A wild yeast strain $3 selected from nature was acclimatized in a PDMS membrane bioreactor system. After continuous three rounds of close-circulating fermentation and acclimatizing cultivation, a fourth round of experiment was conducted.By comparing ferment performances during the first and fourth rounds of experiments, adaptive evolution and acclimatization of the wild yeast were analyzed.The results indicated that the ethanol yield and glucose conversion ratio increased by 42.9% and 2.]% respectively,and the cell mortality ratio decreased by t l.04%.Comparing with commercial ADY,the evolved strain of the wild yeast also behaved better fermentation performance.It was shown that in the close-circulating fermentation system with the membrane bioreactor,the wild yeast could be acclimatized.关键词
