The Genus <i>Amylomyces</i>

Abstract

SUMMARYAmylomyces is a monotypic genus containing the somewhat variable species A. rouxii Calmette. Certain species of Chlamydomucor and Boedijn's species Rhizopus chlamydosporus are synonyms. Strains vary from somewhat restricted sterile white colonies to light gray-brown colonies containing many abortive sporangia. All strains produce abundant chlamydo-spores. During growth in liquid media containing glucose as the carbon source, the glucose is exhausted during the first 3 da and lactic acid is formed that is used as a secondary carbon source after a short lag period. The pattern of utilization of sucrose, maltose, and glycerol by strains of Amylomyces rouxii and Rhizopus oryzae supports the morphological data that make these two genera distinct.
