Abstract excerpt
Thirty-nine riboflavin-deficient mutants have been isolated from three yeast strains of Pichia guilliermondii (ATSS 9058, VKM Y-1256, VKM Y-1257) and F5-121 mutant which is capable of production of large amounts of riboflavin in the presence of iron in the medium. All mutants were divided into five groups according to the nature of precursors accumulated in the medium and growth reaction in media with...
