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]
The expansive genus Aspergillus is currently divided into six subgenera of which many are further split into a total of 27 sections. [6] Subgenus Circumdati, divided in 10 sections. Subgenus Nidulantes, divided in 9 sections. Subgenus Fumigati, divided in 4 sections. Subgenus Aspergillus, divided in 2 sections. Subgenus and section Cremei
Aspergillus restrictus is a species of fungus in the genus Aspergillus. It is from the Restricti section. [3] The species was first described in 1931. [1] It is xerophilic, frequently found in house dust. Studies have suggested that it is an allergen implicated in asthma.
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).
Unmodified trypsin has its highest activity between 35 °C and 45 °C. After the modification, the optimal temperature is changed to the range of 50 °C to 55 °C. [ 16 ] [ 26 ] Other enzymes used for in-gel digestion are the endo proteases Lys-C , [ 27 ] [ 28 ] [ 29 ] Glu-C , [ 30 ] [ 31 ] [ 32 ] Asp-N [ 33 ] and Lys-N .
