Production of D(-)lactic acid from cellulose by simultaneous saccharification and fermentation using

Abstract

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 °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.
