Aspergillus viridinutans explained

Aspergillus viridinutans is a species of fungus in the genus Aspergillus. The species was first isolated in Frankston, Victoria, Australia and described in 1954.[1] It is from the Fumigati section of Aspergillus.[2] Several fungi from this section produce heat-resistant ascospores, and the isolates from this section are frequently obtained from locations where natural fires have previously occurred.[3] A. viridinutans has been identified as the cause of chronic aspergillosis.[4] The mycotoxin viriditoxin was first identified in A. viridinutans.[5] [6] A draft genome sequence of the strain derived from the original species description has been generated.[7]

Growth and morphology

A. viridinutans can be cultivated on different medium sources, including both Czapek yeast extract agar (CYA) plates and Malt Extract Agar Oxoid® (MEAOX) plates. The growth morphology of colonies can be seen in the pictures below.
