Asexual spores are formed within sporangia, which break to release the spores when mature. Germination of these spores forms the haploid hyphae of a new mycelium. R. stolonifer grows rapidly at temperatures between 15 and 30 degrees C[1].
Rhizopus stolonifer is a heterotrophic species (Schipper 1984), in that sexual reproduction occurs only when opposite mating types (designated + and -) come in contact. Successful mating results in the formation of durable zygospores at the point of contact. Subsequently, the zygospore germinates and forms a sporangiophore whose sporangium contains both + and - haploid spores. A heterotroph (Greek heteron = (an)other and trophe = nutrition) is an organism that requires organic substrates to get its carbon for growth and development. ...
There are three varieties: R. stolonifer var. stolonifer produces straight, erect sporangiophores, whereas those of R. stolonifer var. lyococcos are curved [1]. A closely related species, Rhizopus sexualis, differs primarily in being homothallic (self-compatible).
Distribution and Habitat
Rhizopus stolonifer has a pandemic distribution. It is also a type of threadlike mold. It is capable of causing opportunistic infections of humans (zygomycosis). It is most commonly found growing on bread and soft fruits such as bananas and grapes. Because its spores are common in the air, it can be grown within a few days by keeping moistened pieces of bread in an enclosed, humid environment. A pandemic (from Greek Ïαν pan all + Î´Î®Î¼Î¿Ï demos people) is an epidemic that spreads through human populations across a large region (for example a continent), or even worldwide. ...
