a Total esters and b Composition of total esters produced in high cell density cultures of EcJW209-212 with or without addition of ethanol. c Ethyl lactate production of EcJW109-117 with addition of 2 g/L of lactate and ethanol. Red rectangle: high copy number plasmid (100); RSF1030: origin of pRSFDuet-1; PT7: T7 promoter; TT7: T7 terminator. All of the strains were induced at 0 h with 0.01 mM IPTG. Each error bar represents 1 s.d. (n = 3)
