From: Combined substrate, enzyme and yeast feed in simultaneous saccharification and fermentation allow bioethanol production from pretreated spruce biomass at high solids loadings

Figure 1

Evaluation of fermentation performance of Thermosacc in a batch simultaneous saccharification and fermentation (SSF) process using spruce slurry. Increase in glucose concentration (diamonds) was observed during the initial prehydrolysis for 24 h at 50°C. After 24 h, the temperature was reduced to 35°C and followed by the addition of yeast cell suspension, minute traces of ethanol production (circles) were observed. The enzyme and yeast loading was 7.5 FPU gWIS-1 and 5 g L-1, respectively. FPU, filter paper units; WIS, water insoluble solids.
