A newly isolated lactic acid producing bacterium Lactobacillus rhamnosus M-23, from a rice washing drainage storage tank was found to produce l-(+)-lactic acid from a non-sterilized mixture of rice washing drainage and rice bran without any additions of nutrients under the simultaneous saccharification and fermentation (SSF) process. The maximum lactate yield attained was 59 g/l with a productivity of 1.23 g/l/h and a product optical purity of 95% corresponding to a conversion of 0.85 g of lactic acid per gram of sugar equivalent.
从一个淘米排水储存罐中分离出的一株产乳酸细菌——鼠李糖乳杆菌 M-23，在未经灭菌的淘米排水和米糠混合物中，通过同步糖化发酵（SSF）过程，无需添加任何营养物质，即可产生 l-(+)-乳酸。最大乳酸得率为 59 g/L，产率为 1.23 g/L/h，产物光学纯度为 95%，对应于每克糖当量转化 0.85 克乳酸。
