Fig. 7From: Efficient biosynthesis of (R)-mandelic acid from styrene oxide by an adaptive evolutionary Gluconobacter oxydans STAContribution of AcrA for G. oxydans WT and G. oxydans STA in cell growth under different environmental stress and final R-MA production. a Growth characterizations of WT, STA and AcrA associated strains are represented by the maximum specific growth rates (h−1). Right bar indicates the color-scale of the growth rate. b Transformation of styrene oxide into R-MA by WT, STA and AcrA associated strains with SpEH or SpEH co-expressing with AcrABack to article page
