The Ability of Dermatophytes to Utilize Methylxanthine as Sole Source of Carbon and Nitrogen

Methylxanthine contains common compounds that widely consumed by human through their presentin food, drink and beverages or through involving in pharmaceutical drugs. Dermatophytes were selected toinvestigate for their ability to utilize three main compounds of methylxanthine as sole source of carbon andnitrogen. Trichophyton mentagrophytes and Epidermophyton floccosum were grown on three types of media:Medium A lacks of carbon source, medium B lacks of nitrogen source and medium C lacks of carbon andnitrogen sources. Two isolated species of dermatophytes revealed well growth on medium A and less on mediaB and C. Dermatophytes showed ability to use methylxanthine as sole source of carbon and nitrogen withefficiency to use carbon than nitrogen.
