Efficient production of L-(+)-lactic acid from raw starch by Streptococcus bovis 148.
Streptococcus bovis 148 was found to produce L-(+)-lactic acid directly from soluble and raw starch substrates at pH 6.0. Productivity was highest at 37 degrees C, with 14.7 g/l lactic acid produced from 20 g/l raw starch. The yield and optical purity of L-lactic acid were 0.88 and 95.6%, respectively.
