Dimorphism in Mucor Species with Emphasis on M. rouxii and M. bacilliformis

  • José Ruiz-Herrera


Different species of Mucorales are characterized by their alternative growth as either hyphae or yeasts depending on the culture conditions; i.e., they are dimorphic. However, not all Mucorales are dimorphic; in fact, some species grow only as hyphal organisms (they are monomorphic), and among these, some grow only aerobically. Yeast growth among some dimorphic species may be induced by anaerobiosis, whereas others require high CO2 tension plus anaerobiosis to grow in the yeast morphology. These different patterns of growth and some representative mucoraceous species are listed in Table I. However, it must be anticipated that this grouping of species is an oversimplification and represents only a broad guideline for discussion. Factors such as the carbon and nitrogen sources, inhibitors, and others may severely affect the growth patterns of the different species listed.
