  • Title: Lactic acid production from corn stover using mixed cultures of Lactobacillus rhamnosus and Lactobacillus brevis.
    Author: Cui F, Li Y, Wan C.
    Journal: Bioresour Technol; 2011 Jan; 102(2):1831-6. PubMed ID: 20943382.
    Abstract:
    Mixed cultures of Lactobacillus rhamnosus and Lactobacillus brevis was studied for improving utilization of both cellulose- and hemicellulose-derived sugars from corn stover for lactic acid production. During simultaneous saccharification and fermentation (SSF) of NaOH-treated corn stover by the mixed cultures, a lactic acid yield of 0.70 g/g was obtained, which was about 18.6% and 29.6% higher than that by single cultures of L. rhamnosus and L. brevis, respectively. Our results indicated that lactic acid yield from NaOH-pretreated corn stover by mixed cultures of L. rhamnosus and L. brevis was comparable to that from pure sugar mixtures (0.73 g/g of glucose/xylose mixture at 3:1 w/w).
