Abstract
Intracellular thiamine decomposing abilities of 52 strains of yeast-like fungi belonging to Torulaspora, Torulopsis, Torula, Cryptococcus, Rhodotorula and Trichosporon were investigated. 0.2g of wet cells from 16 strains could decompose over 50 per cent of 3 μg thiamine under a given experimental condition. Evidence was obtained to suggest that thiamine decomposing enzyme, "thiaminase" is widely distributed in the yeast-like fungi.
