  • Title: Temperature cycling to improve the ethanol production with solid state simultaneous saccharification and fermentation.
    Author: Chen HZ, Xu J, Li ZH.
    Journal: Prikl Biokhim Mikrobiol; 2007; 43(1):65-8. PubMed ID: 17345861.
    Abstract:
    Simultaneous saccharification and fermentation (SSF) widely used in submerged state could be effective in solid state. Solid state SSF was first compared with solid state separate hydrolysis and fermentation on ethanol production. Ethanol yield using solid state separate hydrolysis and fermentation (SHF) in 5 days was only half of that in solid state SSF in 3 days. In solid state SSF, the ethanol concentration using temperature cycling (10 h at 37 degrees C followed by 15 min at 42 degrees C) was 2 times that using constant 37 degrees C within 72 h, reached 5.2%.
