Candida albicans is a kind of diploid yeast that commonly occurs among the human gut microflora. C. albicans is an opportunistic pathogen in humans. Abnormal over-growth of this fungus can occur, particularly in immunocompromised individuals. [7] C. albicans has a parasexual cycle that appears to be stimulated by environmental stress. [8]
The light-absorbing compound in the fungus cell membranes had the effect of turning the water black. [5] While there are many cases of extremophiles (organisms that can live in severe conditions such as that of the radioactive power plant), a hypothetical radiotrophic fungus would grow because of the radiation, rather than in spite of it.

Those exposed to the sun typically contain melanin and are resistant to high temperatures, dryness and low nutrition. Species that are common elsewhere (e.g. Penicillium spp. and common soil Aspergillus spp. ) do not thrive in these conditions.
Aspergillus flavus is unique in that it is a thermotolerant fungus, so can survive at temperatures that other fungi cannot. [12] [13] A. flavus can contribute to the storage rots, especially when the plant material is stored at high moisture levels. A. flavus grows and thrives in hot and humid climates. [10]
It can reproduce sexually with itself throughout its life cycle. [13] Cryptococcus luteus is parasitic on Granulobasidium vellereum, a corticioid fungus, and is known from England and Italy. [14] It too is not known to produce a yeast state. [15] Cryptococcus amylolentus was originally isolated as a yeast from beetle tunnels in South African ...
Facultative anaerobes can grow with or without oxygen because they can metabolize energy aerobically or anaerobically. They gather mostly at the top because aerobic respiration generates more adenosine triphosphate (ATP) than either fermentation or anaerobic respiration. Microaerophiles need oxygen because they cannot ferment or respire ...
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]
Some species can cause infection in humans and other animals. Some infections found in animals have been studied for years, while other species found in animals have been described as new and specific to the investigated disease, and others have been known as names already in use for organisms such as saprophytes .
