ABSTRACT

The inhibitory effect of molybdenum ions on growth of yeasts at pH 5.5 was found to be decreased by aldoses in the following order: D-talose greater than L-mannose greater than L-ribose greater than D-lyxose greater than L-galactose greater than L-arabinose greater than L-glucose greater than L-xylose. Increased concentrations of molybdenum brought about morphological changes of yeast cells. Cells grown under these conditions were smaller, had thicker walls and formed clusters.
