  • Title: Fermentative production of DL-lactic acid from amylase-treated rice and wheat brans hydrolyzate by a novel lactic acid bacterium, Lactobacillus sp.
    Author: Yun JS, Wee YJ, Kim JN, Ryu HW.
    Journal: Biotechnol Lett; 2004 Oct; 26(20):1613-6. PubMed ID: 15604807.
    Abstract:
    Rice and wheat brans, without additional nutrients and hydrolyzed by alpha-amylase and amyloglucosidase, were fermented to DL-lactic acid using a newly isolated strain of Lactobacillus sp. RKY2. In batch fermentations at 36 degrees C and pH 6, the amount of lactic acid in fermentation broth reached 129 g l(-1) by supplementation of rice bran with whole rice flour. The maximum productivity was 3.1 g lactic acid l(-1) h(-1) in rice bran medium supplemented with whole rice flour or whole wheat flour.
