Colony morphology may be affected by carbon source, colony age, temperature, light and substrate, with colonies ranging from homogeneous to sectored, yeast-like to filamentous growth, and from small to large.
The physical appearance of a colony can be affected by several environmental and biological factors, such as nutrient availability, age, temperature, light exposure, and substrate composition. This diversity in morphology is reflected in the wide range of colony types, including uniformity, segmentation, yeast-like or filamentous growth patterns, and varying sizes.
