Fig. 6From: Engineering xylose metabolism for production of polyhydroxybutyrate in the non-model bacterium Burkholderia saccharixylR expression affects the growth rate of B. sacchari. Late-exponential cells grown in MMG were diluted 1:100 in MMX with increasing concentrations of IPTG (0–500 µM) and transferred to 96-well plates. Optical density (OD600 nm) was measured in triplicate every 15 min for 24 h. The μmax change (%) was determined by comparing the growth rate of each strain with the control strain expressing RFP induced with the same concentration of IPTGBack to article page
