Thus it is important to study the possible pathogenicity
of biocontrol yeasts in humans and animals. In a previous study,
the antagonistic activity of 234 viticultural yeasts against a Botrytis
cinerea strain (gray rot) were studied. However,
activity of these yeasts against filamentous fungi causing sour rot
was not assayed Therefore, the current study analyzed viticulture
yeasts as biocontrol agents in vivo againstfilamentous fungi causing
sour rot.The pathogenicity of bioactive strains was tested in vitro.
