IN a prorioum

pepor on hydroxylation of Reichmtein's substance S (I) bY ricroorganisus, it was reported that a new tertiary hydrorylatod derivative (II), which was assaued to be as 88-hYdrorY1 derivative, uas obtained fro= I iu good Yields by the use of Ceroospera relonis [Cormespora melonis (eke) -1, Compound II was obtained as colorless needles (r.p. aa5-2aV°C, Cali +115°)*a which shewed a positin color test with alkaline triphosY1 totrasolius chloride and iafrarod absorption bauds of A4-3-kotoso and aO-kotone. AcetYlation of II gava a monoacotato (III, u.p. ail-2ia"c, Cr3z4 +14s").

Experiments in batch-fermenters have demonstrated that the llfi-and 19-hydroxylation of Reichstein's Substance S by Pellicularia filamentosa ceases in the absence of glucose. The effects of glucose consumption rate and growth rate on hydroxylation have been investigated using chemostat cultures. Wit
