摘要
Abstract
Plackett-Burman design method was used to screen seven factors of affecting phenyllactic acid production by Lactobacillus plantarum LY-78.The results showed that：the addition amount of glucose,phenylalanine,Tween-80 was the key factor,on the basis of steepest ascent method approaching optimal response surface region,response curve method was used to research optimal level range of those 3 remarkable factors to determine that optimum was Glucose 24 g·L-1,phenylalanine 13 g·L-1 and Tween-80 7.4 mL·L-1,the output of phenyllactic acid was 2.13 g·L-1,which was 7.65 times than before optimization,higher than current phenyllactic acid strains.关键词
