Improved heterotrophic biosynthetic production of ascorbic acid is obtained using ascorbic acid-producing microalgae in particular of the genus Chlorella and the genus Prototheca, as the microorganism source and growing, the culture undera controlled pattern of carbon source supply. Greatly improved ratios of ascorbic acid to total carbon source supplied as well as enhanced concentrations of ascorbic acid in the fermentor are obtained. C. pyrenoidosa UV 101-158 was deposited at the A.T.C.C. on June 27, 1985 and given Accession No. 53170.

Amélioration de la production biosynthétique hétérotrophe d'acide ascorbique par l'utilisation d'algues microscopiques produisant l'acide ascorbique, plus particulièrement des genres Chlorella et Prototheca, comme source et en soumettant les cultures à un régime contrôlé d'apport de carbone. Le rapport acide ascorbique/apport de carbone total est ainsi bien meilleur, et les concentrations d'acide ascorbique dans le fermenteur sont accrues. C. pyrenoidosa UV 101-158 a été déposé le 27 juin 1985 à l'A.T.C.C. et a reçu le numéro 53170.
