Abstract
Yeasts are spoilage organisms in many food processing industries, where
they may grow as biofilms on surfaces of process equipment. Relevant
information about the adhesion characteristics of food spoilage yeasts is
needed to be able to efficiently prevent the early stages of biofilm formation
by control of process parameters. Hydrophobicity has been found to affect
attachment of microbial cells to solid surfaces. In this study, the
adhesiveness and hydrophobicity of yeast cells isolated from food production
processes was investigated. A trend between strong hydrophobicity and high
adhesion rate could be observed. The most hydrophobic yeast strains belonged
to the species Candida intermedia, Rhodotorula mucilaginosa and
Zygosaccharomyces rouxii, whereas the most adhesive strains belonged to the
same species and in addition to Trichosporon asahii. However, a clear
correlation between adhesion and hydrophobicity could not be shown. Probably
other cell surface properties in addition to hydrophobicity also affect the
adhesion rate of yeast cells to surfaces.
