秸秆预处理对米根霉发酵产L-乳酸的影响
The Effect of Pretreatment of Stover on the L-lactic Acid Production by Rhizopus oryzae
摘要
Abstract
[ Objective ] The aim was to improve utilization of stover. [ Method ]The effects of different detergent pretreatments of stover on lactic acid production by stover hydrolysate fermentation was investigated. [ Result ] The results showed that 1.98 g/L lactic acid was produced with the stover hydrolysate as carbon source by fermentation of Rhizopus oryzae and the conversion rate was 5.36% after 36h. The conversion rates of lactic acid were all increased by the pretreatments of stover with neutral and alkalic detergents. Furthermore, the effect of 2% soap powder pretreatment was the best, by fermentaion of hydrolysis resolution of the pretreatmented stover, 8.68 g/L lactic acid was obtained after 36h, when fermentation time reached 60h, lactic acid production arrvived at the top ( 10.64 g/L), and the conversion rate was 43.02%. [ Conclusion ] Soap powder pretreatmen was an effective method to stover.关键词
