title: Amino acid metabolism of Malassezia furfur.
abstract: The mechanism responsible for the hypopigmentation which follows pityriasis versicolor (P.V.) infection has not yet been satisfactorily explained. This work was done in order to study the effect of Malassezia furfur on the decomposition or the utilization of the amino acid tyrosine in vitro. No effect could be noted, which points to the assumption that the effect of the causative fungus of P.V. on melanogenesis is most probably due to the blocking of melanine synthesis by one of the product of M. furfur metabolism without using tyrosine.
