Abstract
Protease-treated wheat bran (20% w/v) of particle size less than 300 µm containing 65% (w/w) starch was used for the simultaneous saccharification and l-(+)-lactic acid fermentation by the mixed cultures of Lactobacillus casei and Lactobacillus delbrueckii. Maximum lactate yield after various process optimizations was 123 gl−1 with a productivity of 2.3 gl−1 h−1 corresponding to a conversion of 0.95 g lactic acid per gram starch after 54 h at 37°C. By using protease-treated wheat bran around tenfold decrease in supplementation of the costly medium component, like yeast extract, was achieved together with a considerable increase in the production level.Keywords
