Abstract
Candida albicans was grown in the darkness, at 28 °C, in a synthetic medium in which glucose and nitrogen concentrations were varied. Numeric appraisal of the chlamydospore index was possible only in the medium where glucose concentration was 0,08 g/l or less. When the glucose concentration raised, pseudomycelial thalli bore numerous chlamydospores but sometimes also chains of cells with a dense granular content. These thalli bud yeast cells which separate and bud again in the medium. The different morphological aspects of the cultures are decribed, illustrated and classified according to the glucose and nitrogen concentration of the medium. Candida albicans a été cultivé à l'obsurité, à 28 °C, dans un milieu de culture synthétique liquide dans lequel on fait varier les concentrations de glucose et d'azote. Des indices de chlamydosporulation ont pu etre calculés pour les milieux contenant au plus 0,08 g/l de glucose. Lorsque la concentration de glucose est plus importante, les thalles pseudomycéliens portent, dans certains cas, de nombreuses chlamydospores, mais aussi des chaines de cellules à contenu dense; ces thalles bourgeonnent des éléments levuriformes qui se détachent et continuent à bourgeonner dans le milieu de culture. Les différentes morphologies rencontrées sont décrites, illustrées et ordonnées en fonction des concentrations de glucose et d'azote du milieu.This publication has 10 references indexed in Scilit:
