Adapted multifeed SSCF with faster feeding and maximum use of pretreatment liquor. a Cell viability (% of CFU/total cell counts) and accumulated WIS content (indicating substrate feeding); and b concentration of glucose, xylose, and ethanol in 22% (w/w) WIS multifeed SSCF of material M2, with the KE-Flow strain, at a constant temperature of 35 °C, or at 35 °C for 24 h, and then at 30 °C. Arrows between the panels indicate cell additions. Values are averages from duplicate experiments, and the error bars show the results of the individual experiments. Details of the substrate and cell feeding can be found in Additional file 1: Table S1
