Fig. 2From: Conversion of cellulose and hemicellulose of biomass simultaneously to acetoin by thermophilic simultaneous saccharification and fermentationTime course of acetoin production from glucose by strain IPE5-4-UD-4 in a fermenter. The cultivation was conducted with 3 L medium containing ~ 120 g L−1 glucose at 50 °C for 72 h. The pH was maintained at 6.5 with stirring at 450 rpm with airflow of 0.6 vvmBack to article page
