Production of D(-)-lactic acid from cellulose by simultaneous saccharification and fermentation using Lactobacillus coryniformis subsp. torquens.
D(-)-Lactic acid was produced from cellulose by simultaneous saccharification and fermentation (SSF) in media containing cellulolytic enzymes and Lactobacillus coryniformis subsp. torquens ATCC 25600 at 39 degrees C and pH 5.4, yielding 0.89 g D(-)-lactic acid g(-1) cellulose at a mean volumetric productivity of 0.5 g l(-1) h(-1). No L(+)-lactic acid was found in the medium.
