摘要
Sixteen strains out of 12 species dermatophytes were examined in respect to their ability of utilizing keratin substrates as the only sources of C and N. The employed keratin substrates included a solubilized preparation of feather keratin /KS/ and native keratin, guinea pig hair and chicken feathers. It has been shown that the preparation KS constitutes a convenient model for a preliminary estimation of fungal keratinolytic activity and it can be a source of information about the localization of these enzymes. It has been found that, among the 16 fungal strains, 13 strains syntetize mainly intracellular keratinases while 3 strains of T. verrucosum release enzymes mainly to the medium. Native keratin from hair and feathers was degraded only by some of the examined strains which, under the experimental conditions, developed characteristic spore forms. Keratin of guinea pigs hair was attacked only by the T. mentagrophytes strains, T. verrucosum and K. ajelloi, and only T. gallinae grew on native keratin from chicken feathers.
