Abstract
Strains of yeast of the species Candida famata are disclosed which can produce 10 grams of riboflavin per liter in 6 days, and in particular, strains identified by ATCC Accession Nos. 20849 and 20850. Riboflavin yields of more than 20 grams per liter in 200 hours have been achieved. Strains of the present invention have increased sensitivity to iron inhibition of flavinogenesis and have enhanced riboflavin production per cell at increased iron concentrations in the fermentation medium.
