| 发明名称 | Lactic acid production method | ||
| 摘要 | A method of producing lactic acid by separating lactic acid produced in a culture solution by microbial fermentation, comprising: a step (A) of filtering the culture solution through a nano-filtration membrane; and a step (B) of distilling a lactic-acid-containing solution produced in step (A) under a pressure of 1 Pa to atmospheric pressure (inclusive) at a temperature of 25 to 200° C. (inclusive) to recover lactic acid. | ||
