Interrelation of the morphology of the colonies and polysaccharide content of cell-wall-modified mutants of Candida spec. "H"

The polysaccharide content of cell wall glucan and mannan from 40 morphological mutants was determined by a modified method according to MANDL et al. (1969) and discussed with reference to morphology of the colonies. A connection between morphology of the colonies and the content in high-molecular mannan was stated: Morphological mutants with a significantly higher or lower content in high-molecular mannan in comparison with the wild strain are characterized by marked changes in morphology of the colonies. In contrast to this, the content in low-molecular mannan and glucan has no influence on the morphological development of a colony.
