Fig. 4From: Metabolic engineering for efficient supply of acetyl-CoA from different carbon sources in Escherichia coliProduction of NAG by engineered strain from glutamate and acetate. The bioconversion medium used here contained 50 mM sodium glutamate and 100 mM sodium acetate. The bioconversion reactions were performed at 37 °C and 200 rpm. H2SO4 was added at different reaction times to adjust the pH valueBack to article page
