| 英文摘要 | In this study, we show that Sporolactobacillus laevolacticus DSM442 can produce D-lactate by using cottonseed as the sole nitrogen source. The cottonseed was enzymatically hydrolyzed and simultaneously utilized during D-lactate fermentation. Under optimal conditions, a high D-lactic acid concentration (144.4 g/L) was obtained in a fed-batch fermentation within 35 h, with an average productivity of 4.13 g/(L h) and a yield of 0.96 g/g glucose. The optical purity of D-lactic acid in the broth was 99.3%, which meets the requirement for use in lactic acid polymerization. Our study represents a cost-effective method for polymer-grade D-lactate production using cheap agricultural wastes. (C) 2013 Elsevier Ltd. All rights reserved. |
