Aspergillus sydowii is a saprophytic fungus found in soil that can contaminate food and is occasionally pathogenic to humans. It is the predominant fungus found on wheat Qu, the most widely used source of raw microorganisms and crude enzymes for Chinese rice wine brewing. [5]
Aspergillusenes are a group of chemical compounds first isolated from a strain of sea fan-derived fungus Aspergillus sydowii. [1] They are sesquiterpenes of the bisabolane-type. [2] A laboratory synthesis of aspergillusene B was reported in 2020. [3]
Aspergillus (/ ˌ æ s p ər ˈ dʒ ɪ l ə s /) is a genus consisting of several hundred mold species found in various climates worldwide. Aspergillus was first catalogued in 1729 by the Italian priest and biologist Pier Antonio Micheli.
Aspergillus sp. growing in potato dextrose agar Potato dextrose agar (BAM Media M127) and potato dextrose broth are common microbiological growth media made from potato infusion and dextrose. Potato dextrose agar (abbreviated "PDA") is the most widely used medium for growing fungi and bacteria. PDA has the capability to culture various bacteria and fungi found in the soil. This agar can be ...
The hyphae of Aspergillus species range in diameter from 2.5 to 4.5 μm. They have septate hyphae, [28] but these are not always apparent, and in such cases they may be mistaken for Zygomycota. [27] Aspergillus hyphae tend to have dichotomous branching that is progressive and primarily at acute angles of around 45°. [27]
Czapek medium, also called Czapek's agar (CZA) [1] [2] or Czapek-Dox medium, is a growth medium for propagating fungi and other organisms in a laboratory. It was named after its inventors, Czech botanist Friedrich Johann Franz Czapek (May 16, 1868 – July 31, 1921) and American chemist Arthur Wayland Dox (September 19, 1882 – 1954).
Aspergillus clavatus is a species of fungus in the genus Aspergillus with conidia dimensions 3–4.5 x 2.5–4.5 μm. It is found in soil and animal manure . The fungus was first described scientifically in 1834 by the French mycologist John Baptiste Henri Joseph Desmazières .
The fungus can grow in a range of environmental conditions; it can grow at temperatures ranging from 6 to 47 °C. [12] As a mesophile, [13] its optimal temperature range is 35-37 °C. [11] It can tolerate pH ranging from 1.5 to 9.8. [12] A. niger is xerophilic, meaning it can grow and reproduce in environments with very little water.
