Fig. 6From: Reducing glucoamylase usage for commercial-scale ethanol production from starch using glucoamylase expressing Saccharomyces cerevisiaeEffect of microbial enzymes on the cell wet weight and ethanol content of glucoamylase expressing strain CIBTS1522. The influence of the acid protease addition with (a) or without urea (b), the xylanase addition with (c) or without urea (d), the cellulase addition with (e) or without urea (f), and the phytase addition with (g) or without urea (h) was shown. Error bars represent the standard deviation from the mean of three replicatesBack to article page
