Analyses of pentose utilization by hexo-/glucokinase deletion strains in the presence of maltose. The strain TSY10-XT was inoculated with 0.5 g (dry biomass)/L in SC medium containing 10 g/L D-xylose (A) or additionally supplemented with 10 g/L maltose (B). The strain TSY10-AT was incubated in SC medium containing 10 g/L L-arabinose (C) or additionally supplemented with 10 g/L maltose (D). The cultivations were performed in shake flasks at 30°C. At different time points, probes were taken, the concentrations of residual sugars analyzed by HPLC, and growth was determined by measuring the OD600 nm.
