Inorganic sulphur sources for the growth of the dermatophyte Microsporum gypseum.
Suitability of 10 inorganic compounds at a concentration of 1 mM as sulphur sources for the growth of the dermatophyte Microsporum gypseum was investigated. Dry mass of the mycelium after a 11-d growth served as indicator. Sodium sulphate, sulphite and also disulphite, peroxodisulphate and dithionite were the best sources. Growth in the presence of sodium thiosulphate and tetrathionate was slightly worse. Sulphide inhibited the growth, which began only after a longer adaptation. Sodium thiocyanate and amidosulphate were not utilizable as sulphur sources.
