Abstract
Both Candida albicans and C. tropicalis produced a remarkable amount of riboflavin-α-glucoside in growing cultures, when grown on a medium containing dextrin and riboflavin. Moreover, it was pointed out that a partially purified enzyme preparation of transglucosyl-amylase prepared by the method of Sawai and Hehre had riboflavin-α-glucoside-forming activity. Maltosyl compounds such as maltose, dextrin and amylose were the effective glucosyl donor, whereas glucose, fructose, sucrose, lactose, trehalose and dextran were inactive.
