Antifungal activity of Wickerhamomyces silvicola

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