Rhizopus arrhizus--a producer for simultaneous saccharification and fermentation of starch waste materials to L(+)-lactic acid.
Rhizopus arrhizus, strain DAR 36017, produced L(+)-lactic acid in a simultaneous saccharification and fermentation process using starch waste effluents. Lactic acid at 19.5-44.3 g l(-1) with a yield of 0.85-0.96 g g(-1) was produced in 40 h using 20-60 g starch l(-1). Supplementation of nitrogen source may be unnecessary if potato or corn starch waste effluent was used as a production medium.
