The Black bread mold, Rhizopus stolonifer, is a common type of fungus. R. stolonifer, commonly known as black bread mold, is a saprophytic zygomycete that feeds on bread, jams, pickles, cheese, and other moist food. The surrounding condition in which the mold resides, is the factor that causes either type of reproduction by the mold. Division: Zygomycota. Rhizopus, cosmopolitan genus of some 10 species of filamentous fungi in the family Rhizopodaceae (formerly Mucoraceae), in the order Mucorales. Mycelium is differentiated into nodes and internodes. Also known as black bread mold. The scientific name for black bread mold is Rhizopus stolonifer. Black bread mold Introduction Kingdom: Fungi Phylum: Zygomycota Class: Zygomycetes Order: Mucorales Family: Mucoraceae Genus: Rhizopus Species: R. stolonifer. It uses nutrients in the bread for its growth, and can reproduce by asexual or sexual reproduction method. This mold gets its nutrients by using enzymes to extract the nutrients from the site it resides on. It comes from the species Rhizopus stolonifer, and it is one of the most common molds on bread. It grows and reproduces the same way that most molds do. Diagram the life cycle of Rhizopus c. Determine the ploidy of the following Rhizopus structures: i. Mycelium hyphae. Niche. a. Classify to phylum. The majority of known fungi belong to the Phylum Ascomycota, which is characterized by the formation of an ascus (plural, asci), a sac-like structure that contains haploid ascospores. on the right is a photo of the mold. This mold is a common type of fungus which tends to grow on bread. Zygospores are fungal seeds that are made from sexual reproduction, a notable feature of bread mold's group, the Zygomycota. What is it? (credit b: modification of work by “polandeze”/Flickr) Ascomycota: The Sac Fungi. Observe black bread mold, Rhizopus, (sexual or with zygospores). Although black bread molds are probably the best-known members of Phylum Zygomycota, they are not the only fungi that grow on bread.So many organisms can, in fact, contribute to bread spoilage that nearly all commercially baked goods have, in the past, had chemicals such as calcium propionate added to the dough to prevent or retard the growth of such organisms. Black bread mold is also called ergot. ii. It is also referred as R. stolonifer. Thallus is white cottony, much branched mycelium. Genus: Rhizopus. Black mold lives by dissolving the bread and absorb the nutrition. In asexual reproduction, the mold makes spores inside a sporangium. The zygomycetes are a relatively small group of fungi belonging to the Phylum Zygomycota.They include the familiar bread mold, Rhizopus stolonifer, which rapidly propagates on the surfaces of breads, fruits, and vegetables.Most species are saprobes, living off decaying organic material; a few are parasites, particularly of insects. 2.

This species of mold can also grow on fruits which cause the fruits to rot. You may have experienced black mold on bread. Rhizopus stolonifer is also known as black bread mold. Black bread mold Scientific classification; Kingdom: Fungi. Rhizopus stolonifer: morphology and reproduction of black bread mold. The other kind of spores is called sporangiospores. Label the following on the figure below: hyphae, zygosporangium w/zygospores, suspensor cells, ploidy. Among other mold species, black mold has the fastest growth. Several species, including Rhizopus stolonifer (the common bread mold), have industrial importance, and a number are … The (b) tips of bread mold are the spore-containing sporangia. Rhizopus, or bread mold, has branching life cycles depending on whether it was produced sexually or asexually.
