Abstract
The present invention is directed to methods for the production of ascorbic acid by culturing organisms of the genus Prototheca and recovering ascorbic acid from the fermentation medium.
Claims23
A process for the production of L-ascorbic acid, the process comprising the steps of:
- (a) culturing an organism of the genus Prototheca in a fermentation medium containing assimilable sources of carbon and nitrogen;
- and
- (b) recovering L-ascorbic acid produced by said organism during said step of culturing.
A process for the production of L-ascorbic acid, the process comprising the steps of:
- (a) culturing an organism of the genus Prototheca in a fermentation medium having a pH of less than about 6 and an available source of oxygen until said fermentation medium has a concentration of extracellular L-ascorbic acid of greater than about 1 mg/l;
- and
- (b) recovering extracellular L-ascorbic acid from said fermentation medium.
