Potential of solid state fermentation for production of L(+)-lactic acid by Rhizopus oryzae

  title={Potential of solid state fermentation for production of L(+)-lactic acid by Rhizopus oryzae},
  author={Carlos Ricardo Soccol and Barbara A Marin and Maurice Raimbault and J. -M. Lebeault},
  journal={Applied Microbiology and Biotechnology},
Production of l(+)-lactic acid by Rhizopus oryzae NRRL 395 was studied in solid medium on sugar-cane bagasse impregnated with a nutrient solution containing glucose and CaCO3. A comparative study was undertaken in submerged and solid-state cultures. The optimal concentrations in glucose were 120 g/l in liquid culture and 180 g/l in solid-state fermentation corresponding to production of l(+)-lactic acid of 93.8 and 137.0 g/l, respectively. The productivity was 1.38 g/l per hour in liquid medium… CONTINUE READING
