Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found in a wide variety of organic substances, including "mature fruits and vegetables", [ 2 ] jellies, syrups, leather, bread, peanuts, and tobacco.
Rhizopus stolonifer is commonly known as black bread mold. [1] It is a member of Zygomycota and considered the most important species in the genus Rhizopus. [2] It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions. [3]
A fermentation starter containing the spores of fungus Rhizopus oligosporus or Rhizopus oryzae is mixed in. [16] The beans are spread into a thin layer and are allowed to ferment for 24 to 36 hours at a temperature around 30°C (86°F). The soybeans have to cool down to allow spore germination and abundant growth of mycelium. Later, the ...
Rhizopus niveus' columellae are the same color as its sporangiophores (almost colorless or pale yellowish-brown). The walls of columellae are smooth. [1] Spores of Rhizopus niveus may be faintly striated, or even lacking in striation, and are also usually elliptical shaped. Zygospores of Rhizopus niveus are bag-shaped and pale yellow or ...
Rhizopus arrhizus is a fungus of the family Mucoraceae, characterized by sporangiophores that arise from nodes at the point where the rhizoids are formed and by a hemispherical columella. It is the most common cause of mucormycosis in humans and occasionally infects other animals. Rhizopus arrhizus spores contain ribosomes as a spore ...
Rhizopus oligosporus is a fungus of the family Mucoraceae and is a widely used starter culture for the production of tempeh at home and industrially. As the mold grows it produces fluffy, white mycelia , binding the beans together to create an edible "cake" of partly catabolized soybeans .
[1] [2] The most common are Rhizopus soft rot (Rhizopus stolonifer), bacterial soft rot (Erwinia chrysanthemii), Fusarium root rot (Fusarium solani), Fusarium surface rot (Fusarium oxysporum), and black rot (Ceratocystis fimbriata). R. stolonifer is a problematic pathogen as it infects fresh wounds occurring during packing and shipping. There ...
Pathogenic genera include Absidia, Apophysomyces, Mucor, Rhizomucor, and Rhizopus. According to a 2008 estimate, the family contains 25 genera and 129 species. [ 2 ]
