Fermentation kinetics of eight different microorganisms grown on OMSW fibre hydrolysate. Each species (Saccharomyces cerevisiae, Schizosaccharomyces pombe, Geobacillus thermoglucosidasius, Clostridium saccharoperbutylacetonicum, Escherichia coli, Zymomonas mobilis, Pseudomonas putida and Rhodococcus opacus) was grown separately in triplicate on 10 mL OMSW fibre hydrolysate supplemented with 1% vitamin-enriched yeast extract and buffered with 40 mM MOPS. Accumulation of products (ethanol, butanol, acetone or triacylglycerol (TAG)) and consumption of glucose (triangle) and xylose (square) are plotted on the primary Y-axis. Optical density at 600 nm (secondary Y axis) was used as a measure of biomass production. All species were inoculated to a starting OD₆₀₀ of 0.05. Note that TAG yield was only measured at 72 h. Culture conditions: *Semi-Aerobic in shake flasks with airlocks; ⁺Anaerobic in serum bottles; circles Aerobic in shake flasks
