Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface. A British study determined that Aspergillus- and Penicillium-type spores were the most prevalent in the indoor air of residential properties, and exceeded outdoor levels. [14]
Even among fungi that reproduce both sexually and asexually, often only one method of reproduction can be observed at a specific point in time or under specific conditions. Additionally, fungi typically grow in mixed colonies and sporulate amongst each other. These facts have made it very difficult to link the various states of the same fungus.
Penicillium spinulosum (spinulosus means with small spines in Latin) is a non-branched, fast-growing fungus with a swelling at the terminal of the stipe (vesiculate) in the genus Penicillium. [ 3 ] [ 4 ] P. spinulosum is able to grow and reproduce in environment with low temperature and low water availability, [ 5 ] and is known to be ...
The surface of a Talaromyces (formerly Penicillium) marneffei colony. Image: James Gathany, CDC. Talaromyces marneffei, formerly called Penicillium marneffei, [1] was identified in 1956. [2] The organism is endemic to southeast Asia, where it is an important cause of opportunistic infections in those with HIV/AIDS-related immunodeficiency.
Penicillium chrysogenum (formerly known as Penicillium notatum) is a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, [ 1 ] but it is mostly found in indoor environments, especially in damp or water-damaged buildings. [ 2 ]
Penicillium simplicissimum is an anamorph species of fungus in the genus Penicillium which can promote plant growth. [1] [3] [4] [5] This species occurs on food and its primary habitat is in decaying vegetations [6] Penicillium simplicissimum produces verruculogene, fumitremorgene B, penicillic acid, viridicatumtoxin, decarestrictine G, decarestrictine L, decarestrictine H, decarestrictine I ...
[8] [failed verification] During the production of traditional Tyrolean smoked and cured ham, both Penicillium solitum and Eurotium rubrum are commonly found. [ 14 ] Furthermore, Penicillium solitum is known to be a pathogen of pomaceous fruit , [ 15 ] P. solitum causes blue rot in pome fruits through its production of polygalacturonase , which ...
Paecilomyces variotii is fast growing, producing powdery to suede-like colonies that are yellow-brown or sand-colored. [8] It is distinguishable from microscopically similar microfungi, such as the biverticillate members of the genus Penicillium (affiliated with the genus Talaromyces) by its broadly ellipsoidal to lemon-shaped conidia, loosely branched conidiophores and phialides with pointed ...
