  • Title: Fermentation of pretreated sugarcane bagasse hemicellulose hydrolysate to ethanol by Pachysolen tannophilus.
    Author: Cheng KK, Ge JP, Zhang JA, Ling HZ, Zhou YJ, Yang MD, Xu JM.
    Journal: Biotechnol Lett; 2007 Jul; 29(7):1051-5. PubMed ID: 17479227.
    Abstract:
    Sugarcane bagasse hemicellulose hydrolysates, pretreated by either over-liming or electrodialysis and, supplemented with nutrient materials, were fermented to ethanol using Pachysolen tannophilus DW06. Compared with detoxification by over-liming, detoxification by electrodialysis decreased the loss of sugar and increased the acetic acid removal, leading to better fermentability. A batch culture with electrodialytically pretreated hydrolysate as substrate was developed giving 21 g ethanol l(-1) with a yield of 0.35 g g(-1) sugar and productivity of 0.59 g l(-1) h(-1).
