The effects of various carbohydrates on BDSF biosynthesis.

(a) DSF and BDSF production of strain ΔrpfC in media XY, XYS, XYT, XYG and XYF. XY medium contains 0.7 g/L K2HPO4, 0.2 g/L KH2PO4, 1.0 g/L (NH4)2SO4, 0.1 g/L MgCl2, 0.01 g/L FeSO4, 0.001 g/L MnCl2, 0.2 g/L yeast extract, pH7.0. XYS medium: XY medium supplemented 2.0 g/L sucrose; XYT: XY medium supplemented with 2.0 g/L starch; XYG: XY medium supplemented with 2.0 g/L glucose; XYF: XY medium supplemented with 2 g/L fructose. (b) DSF and BDSF production time courses in XYS medium. Data are means ± one standard deviation of three independent assays. Different letters indicate significant differences between treatments (LSD at P = 0.05).
