  • Title: An evaluation of the potential of Acacia dealbata as raw material for bioethanol production.
    Author: Ferreira S, Gil N, Queiroz JA, Duarte AP, Domingues FC.
    Journal: Bioresour Technol; 2011 Apr; 102(7):4766-73. PubMed ID: 21316950.
    Abstract:
    In this work, the potential of Acacia dealbata as raw material for ethanol production was evaluated, as well as its composition with regard to cellulose, hemicelluloses, lignin, extractives and ash. The tree samples were subjected to several dilute acid pretreatments using a combined severity parameter ranging from 0.7 to 3.7. The highest ethanol concentration obtained was 10.31 g ethanol/L within 24 h by using a separate hydrolysis and fermentation of the water insoluble fraction after pretreatment at 180 °C with 0.8% of sulfuric acid for 15 min. With simultaneous saccharification and fermentation, results obtained for the washed solids of water insoluble fraction were better than those obtained with the whole slurry.
