[Antifungal Activity of Wickerhamomyces silvicola].

Wickerhamomyces silvicola strain Y-178 was shown to secrete a mycocin with a fungicidal effect. It exhibits the highest activity at pH 4.5 and elevated ambient osmotic pressure. Over 140 species belonging to 45 genera of ascomycetous yeasts were sensitive to the mycocin, while basidiomycetous species were resistant. Taxonomically homogenous species usually exhibit a homogenous response to mycocins.
