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 ]
"We don't recommend cutting mold off of bread, because it's a soft food," Marianne Gravely, a senior technical information specialist for the United States Department of Agriculture, told NPR ...
The mold spore's roots go much farther into bread than our eyes can see, according to the USDA.
It spreads over the surface of bread and other food sources, sending hyphae inward to absorb nutrients. In its asexual phase it develops bulbous black sporangia at the tips of upright hyphae, each containing hundreds of haploid spores. As in most zygomycetes, asexual reproduction is the most common form of reproduction.
Neurospora crassa is a type of red bread mold of the phylum Ascomycota. N. crassa is used as a model organism because it is easy to grow and has a haploid life cycle: this makes genetic analysis simple, since recessive traits will show up in the offspring.
Asexual reproduction often occurs continuously. In heterothallic species, sexual reproduction occurs when opposite mating types (designated + and -) come into close proximity, inducing the formation of specialized hyphae called gametangia. The gametangia grow toward each other, then fuse, forming a diploid zygote at the point of fusion.
Most of the time, ingesting mold isn’t anything to worry about. However, some molds can cause an allergic reaction or make you sick. You’re likely not going to eat moldy bread intentionally ...
Candida albicans growing as yeast cells and filamentous (hypha) cells. A dimorphic fungus is a fungus that can exist in the form of both mold [1] and yeast.As this is usually brought about by a change in temperature, this fungus type is also described as a thermally dimorphic fungus. [2]
