Eleven strains belonging to two physiological races of Saccharomyces cerevisiae endowed with different abilities of forming films at air‐liquid interfaces were analysed in relation to cell fatty acid composition and cell hydrophobicity. Extensive individual differences in fatty acid profiles were observed both in the film and in the non‐film phase. The ability of the cells to form a floating film seems to be an implicit strain character associated with an elevated unsaturation level and a mean chain length of fatty acid residues, as well as cellular hydrophobicities higher than those shown by non‐film‐forming strains belonging to the same species.
