Oversynthesis of Riboflavin in the Yeast Pichia guilliermondii is Accompanied by Reduced Catalase and Superoxide Dismutases Activities

Iron deficiency causes oversynthesis of riboflavin in several yeast species, known as flavinogenic yeasts. Under iron deprivation conditions, Pichia guilliermondii cells increase production of riboflavin and malondialdehyde and the formation of protein carbonyl groups, which reflect increased intrac...
