The micrographs were Aspergillus spp. but the yellow culture is Aspergillus flavus.

Thank you very much, wish you good luck.

Interesting question but it is away from my field

The green culture looks like Aspergillus flavus and the black ones look like Aspergillus niger. But you need to follow the classification taxonomy key to confirm the species.

Sorry for any inconvenience caused, the colour is green, not yellow as stated earlier on.

The green culture is Aspergillus flavus

the isolates seems to be a Aspergillus flavus and Aspergillus niger based on the colony and microscopic observations. But, it requires further confirmation for précised identification by an expertise and molecular identification.

this text book might help: Identification of Common Aspergillus Species by Maren A Klich.,

According to the colonies images, it seems that the black colony is Aspergillus niger, while the green colony is may be A. flavus. So, the microscopic test is very necessary to give well identification.

Good luck.

Hi Musa

I think:

The first image = the yellow culture is Aspergillus flavus

Second and third images = the black culture is Aspergillus niger
