甘蔗糖蜜发酵生产谷氨酸的研究
Study on the Fermentation of Sugarcane Molasses into L-glutamic Acid
【摘要】 研究了以甘蔗糖蜜为原料,采用温度敏感型突变株发酵生产L-谷氨酸的补料分批发酵工艺条件。结果表明,优化条件下,在10L自控发酵罐中发酵生产L-谷氨酸的平均产量为125g/L,糖酸转化率为60.14%。
【Abstract】 Feed-batch fermentation by Temperature-sensitive mutant was studied for the production of L-glutamic acid grown on sugarcane molasses. Results showed that on the optimum Feed-batch fermentation condition, the average yield of L- glutamic acid was 125g/L and the conversion rate is 60.14%.
