Figure 5From: Single-step ethanol production from lignocellulose using novel extremely thermophilic bacteriaFermentation products on pretreated poplar in fermentors. Cellulolytic strain Caldicellulosiruptor sp. DIB 004C (A) and a co-culture of DIB 004C and of the non-cellulolytic strain Thermoanaerobacter sp. DIB 004G (B) were grown on 20 g/l (dry mass) of steam explosion pretreated poplar wood in fermentors at 72°C with pH stabilized at 6.75.Back to article page
