- Abstract
Rice and wheat brans, without additional nutrients and hydrolyzed by a-amylase and amyloglucosidase, were fermented to dl-lactic acid using a newly isolated strain ofLactobacillussp. RKY2. In batch fermentations at 36 °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.
