Six levels of crude protein (0.21 to 3.36 g/L) were investigated as the nitrogen source for production of L-lactic acid by Rhizopus oryzae with respect to the influence on L-lactic acid yield, biomass and mycelia morphology. Increases in crude protein from 0.21 to 1.68 g/L led to an increase in L-lactic acid concentration from 6.48 to 57.7 g/L. However, further increases beyond 1.68 g/L did not present continuing increases in L-lactic acid yields.
