The production of riboflavin (Vitamin B2) by Candida guilliermondii Wickerham cultivated on solar-containing medium was stimulated in presence of corn steep liguor (2 g/l), corn oil (0.1 g %), arginine, phenylalanine (1m mole/l) or COSO4. 7H2O (1000 ug/l). On the other hand, emulsifying agents strongly inhibited yeast growth and vitamin production. Similarly, FeSO4. 7H2O and MnSO4. 4H2O at 50 and 200 ug/l levels respectively also showed inhibitory effect. Among the tested purines, xanthine enhanced the vitamin production.
