Aspergillus flavus

Possible ID: Aspergillus flavus

 

Phylum: Ascomycota

Class: Eurotiomycetes

Order: Eurotiales

Family: Trichocomaceae

 

Isolation and culturing methods:

Air sample taken in between Rooke Chemistry and Van Lit. for seven minutes. Air sample was taken on a plate with malt extract agar plus antibiotics. Air sample was stored at room temperature for one week in order to let collected culture grown. After one week, samples were taken and the isolates were transferred from the main plate to an new one with the same agar conditions. Isolate was stored at room temperature for one week in order to obtain pure culture.

 

Culture appearance and growth:

White spots embedded in the agar with slight teal/green coloring underneath. Fast growth rate, spores and hyphae being produced, almost completely covering the plate, in spots. Hyphae about 3.0-5.2 microns wide, septate but no clamp connections.

Spore production:

Spores are 2.8-3.4 x 2.9-3.9 microns and were embedded in agar. Appear light green/teal to naked eye, little coloration when under the microscope. Fairly round, slight oval shape. Conidia produced about 29.8-30.5 x 25.4-29.9 microns.
