n-alkanes as a substratum for riboflavin production. I. Investigations of the dynamics of the flavinogenesis in chosen yeasts of the genus candida.
For the first time the flavinogenic abilities of Candida flareri on a simple, fully defined medium with hydrocarbons were demonstrated. C flareri and C. guilliermondi on a synthetic medium with biotin and n-alkanes (n-decane and hexadecane) overproduce riboflavin with a considerable but varying efficiency. Among the two hydrocarbons examined n-hexadecane proved to be a more favourable source of carbon for the biosynthesis of this vitamin than n-decane. The quantities of riboflavin accumulated by C. flareri in an aerated culture are twice higher than those for C. guilliermondii (50.5 microgram/ml on hexadecane) in analogous conditions.
