Abstract
A new flavin was found in the culture medium of Schizophyllum commune, a Basidiomycete. The flavin was converted from riboflavin in a good yield. Some relationship between the flavin and L-malate production was observed.
This result supplys evidence that there are, at least, three different metabolic pathways of riboflavin among the three classes, Ascomycetes, Phycomycetes and Basidiomycetes.
