Growth and morphology

A. microcysticus has been cultivated on both Czapek yeast extract agar plates and Malt Extract Agar Oxoid® plates. The growth morphology of the colonies can be seen in the pictures below, where distinct differences in texture, coloration, and edge structure are evident depending on the medium used. These visual variations may reflect the organism’s metabolic response to differing nutrient compositions, and can be useful for species identification or comparative analysis.
