Utilization of white rice bran for production of l-lactic acid

In this study, white rice bran, a byproduct of rice milling, was developed for l-lactic acid production. The hydrolyte of white rice bran could be used as carbon and nutrient sources for l-lactic acid fermentation with a productivity of 3.73 kg m−3 h−1 in batch fermentation, which was 1.52 times higher than that of the control medium with glucose and yeast extract. These results showed a potential for development of high value-added products from white rice bran.

► We used firstly agricultural byproduct - white rice bran to produce l-lactic acid. ► Explained why rice bran can be used as nutrient from vitamins, amino acids. ► We used corn steeping liquor for increasing the production of lactic acid. ► WRBS, RAH, CSL was good combination for producing l-lactic acid.
