What is the color of Rhizopus stolonifer?
To identify Rhizopus stolonifer look for either a grayish fluffy mass or a blue or yellow colored coating on the substrate. Black spores are also visible to the eye on the surface of the substrate, which may look like black specs.
What is the hyphae of Rhizopus?
Rhizopus fungi are characterized by a body of branching mycelia composed of three types of hyphae: stolons, rhizoids, and usually unbranching sporangiophores. The black sporangia at the tips of the sporangiophores are rounded and produce numerous nonmotile multinucleate spores for asexual reproduction.
Does Rhizopus stolonifer produce hyphae?
Distinguishing Features: Rhizopus stolonifer is unique in that it carries out sexual reproduction when its hyphae of different mating types come into contact, producing the resilient zygospores.
Is Rhizopus a black fungus?
Rhizopus stolonifer is commonly known as black bread mold. It is a member of Zygomycota and considered the most important species in the genus Rhizopus….

What stain is used to identify Rhizopus?
Cotton blue: It stains the fungal elements as well as intestinal parasitic (cyst, ova, and oocyst) and nonparasitic structures (vegetable cells, mucus, muscle fibers, and other artifacts).
What stain would you use to identify Rhizopus?
Calcofluor white, Gomori’s methenamine silver (GMS), hematoxylin and eosin (H and E), and periodic acid–Schiff stains are used for a prompt identification of the fungus.
Does Rhizopus have Aseptate hyphae?
Yes, Rhizopus reproduce asexually as well as sexually. Asexual reproduction is by the formation of sporangiospores and chlamydospores. Sexual reproduction is by fusion of two compatible hyphae.
Does Rhizopus have septate hyphae?
Rhizopus belongs to zygomycetes. Unbranched, septate and coenocytic: This type of mycelium is found within deuteromycetes. This is also called as Fungi imperfect.
Does Rhizopus stolonifer have chitin?
Rhizopus stolonifer grows primarily as mycelia, which consists of long filamentous cells, or hyphae, that lack cross walls, known as septa. The lack of septa enables the mold to be named coenocytic. Coenocytic means that the mold is a multinucleate cell enclosed by one cell wall that contains chitin.
What type of fungi is Rhizopus stolonifer?
Rhizopus, cosmopolitan genus of some 10 species of filamentous fungi in the family Rhizopodaceae (formerly Mucoraceae), in the order Mucorales. Several species, including Rhizopus stolonifer (the common bread mold), have industrial importance, and a number are responsible for diseases in plants and animals.
How do you distinguish Rhizopus species?
Some morphological features, such as the length of rhizoids and sporangiophores, the diameter of sporangia, the shape of columellae, and the size, shape and surface texture of sporangiospores aid in differentiation of Rhizopus species from eachother.
What is Rhizopus stolonifer used for?
R. stolonifer is used to produce fumaric acid, lactic acid, and cortisone, and R. delemar produces fumaric acid and biotin. In Asia several species are important in some foods, such as tempeh, and in many traditional alcoholic beverages.
What is Rhizopus stolonifer?
The species Rhizopus stolonifer is a cosmopolitan fungus taxonomically located as: The Rhizopus stolonifer It is a filamentous fungus that presents unbranched sporangiophores, 2 mm long by 20 μm thick.This aerial hypha, peduncle or sporangiophore emerges from well-developed rhizoids and is dark brown in color.
Where does septum synthesis occur in Rhizopus stolonifer?
In presence of the adverse conditions, septum synthesis occurs within the mycelium and each intercalary mycelium forms a thick resting spore called chlamydospore. The Sexual reproduction of Rhizopus stolonifer occurs in presence of unfavorable conditions by means of gametangial copulation.
What is the morphology of Rhizopus hyphae?
Rhizopus species have haploid mycelium composed of haploid, multinuclear, coenocytic hyphae. Their morphology is characterized by the presence of stolons, rhizoids, and sporangiophores. Stolons are well or poorly developed.
Can Rhizopus stolonifer grow on czapek dox?
At the laboratory level, Rhizopus stolonifer it is grown on various culture media, including those containing amino compounds and ammonium salts. However, it does not grow on media with a high nitrate content, such as Czapek Dox Agar, which has nitrate as the only source of nitrogen.
