Fig. 5From: Renewable synthesis of n-butyraldehyde from glucose by engineered Escherichia coli Comparison of yeast extract (a, b) and tryptone (c, d) concentration in M9 glucose media for n-butyraldehyde production. Product concentrations and butyraldehyde-to-butanol ratios sampled at a, c 24 h and b, d 48-h post-switch to anaerobic condition. Strain KS8/pKU48/pRW18/pRW22 was used for n-butyraldehyde productionBack to article page
