Selection of integration site of xylBC to increase 1,2,4-BT production. A Scheme of the integration mode of xylBC in E. coli BT-7, E. coli BT-8, and E. coli BT-9. B Performance of E. coli BT-7, E. coli BT-8, and E. coli BT-9 in transforming xylose into 1,2,4-BT. The fed-batch fermentation was carried out in 300 mL shake flask at 180 rpm and 30 °C. When xylose concentration was lower than 5 g/L, 10 g/L xylose was added. Values are the average ± SD (n = 3 independent experiments)
