When the medium containing
15 g/l of yeast extract was used, the maximum lactic acid concentration (134.9 g/l) and the maximum productivity (4.3 g/l h) were obtained
at molasses concentrations of 333 g/l (equivalent to 170 g/l of total sugar) and 130 g/l (equivalent to 68 g/l of total sugar), respectively. In
addition, l(+)-lactic acid content of lactic acid produced from molasses was above 98% in all cases experimented in this study.
