Utilization of amines by yeasts.
461 Strains of the yeast collection of the Centraalbureau voor Schimmelcultures (CBS) were screened for their ability to utilize 9 different amines as a sole carbon and energy source and/or as nitrogen source. A miniaturized technique with microtiter plates was used. None of the primary and methylated amines tested (i.e. methylamine, dimethylamine, trimethylamine, tetramethylammonium chloride, choline, ethylamine, propylamine, butylamine and benzylamine) were utilized as a carbon and energy source, although the majority of yeasts (86%) were able to utilize one or more of these compounds as a nitrogen source. The ability to utilize ethylamine and higher homologues occurred more frequently than the ability to utilize methylated amines. In almost all genera the utilization of primary and methylated amines was found, with utilization among yeasts and the inability of these organisms to utilize amines as a carbon and energy source is discussed.
