The highest amount of L-lactic acid produced from xylose is 195 g/L, the optical purity is over 99%, the yield is up to 0.98, and the productivity is up to 2.7 g/L per hour. The highest amount of L-lactic acid produced from reducing sugars in xylitol byproducts is 106 g/L, the optical purity is over 99%, and the productivity is up to 2.08 g/L per hour. The B. coagulans strains XZL4 (DSM No. 23183) and XZL9 (DSM No.Type: GrantFiled: November 22, 2010Date of Patent: July 23, 2013Assignee: Shanghai Jiao Tong UniversityInventors: Ping Xu, Limin Wang, Bo Zhao, Cuiqing Ma, Fei Su, Fei Tao, Hongzhi Tang
