Life Cycle

Like all species that belong to the Phylum, Ascomycota, Aspergillus can reproduce sexually or asexually. In most cases they reproduce asexually and a few like A. Niger are observed to produce sexually.

Typically, Aspergillus reproduces asexually.  Spores are released in the air and then carried by the wind. After landing in a place where there are good conditions, the start to germinate producing foot cells. More branching occurs and elongation of hyphae creating a mass of hyphae or mycelium. Soon conidiophores grow from the foot cells and then the head made of spores (conidial head).
