Fermentation of detoxified hemicellulose extract. Strain M1732 was grown in TSC7 medium containing hemicellulose extract at 1 L volume at 51 °C at pH 5.8. The fermentor contained 42 g/L available sugar (76 % xylose, 11 % mannose, 6 % glucose, 5 % galactose, and 2 % arabinose, as polymeric hemicellulose) at the start, and was fed an additional 25 g/L over two feedings at 24 and 47 h. The hemicellulose was detoxified by lime treatment and nanodiafiltration
