Candida guillermondii strain ATCC 9058 was grown on liquid brewery waste. The substrate contained 22 mg/ml of total carbohydrates of which approximately 60 per cent was reducing sugars. Maximum production of riboflavin was achieved at a pH 4, temperature of 30.degree. C, after 3 days of fermentation in a medium supplemented whith biotin 1 .mu.g/l. No significant differences were observed upon riboflavin production on the addition to the brewery waste of nitrogen sources such as amino acids (other than methionine), inorganic ammonio, zinc, cobalt, phosphorus, magnesium, and certain iron complexing agents.
