As prelimnary experiments in finding the requisite metal in Trichophyton, detection of elementary inorganic composition in the fungal body was carried out by the spectroscopic analysis, using four strains, i.e. Trichophyton interdigitale, T. purpureum, T. asteroides, and Epidermophyton inguinale. These dermatophytes were cultured in an ordinary Sabouraud medium, Landis medium which is suited for spore formation, and in Fulmer medium which does not contain organic nitrogen. The fungal body harvested from each medium was ignited, and the residual ash was analyzed. As the chief componental elements, P, K, Mg, Ca, an dNa were found, and Fe, Al, and Cu as the minor componental elements. Fifteen elments were also found as the microcomponental element. The metals not detected were As, Bi, Co, Hg, and Li. There was no characteristic in the elements found by different strains and it seems that the kind and amount of elements found in the fungal body are dependent on the composition of the medium.
