Colony Morphology of Bacteria • Microbe Online
WebSince bacteria were first cultured on solid media, describing the appearance of bacterial colonies has been an important tool for microbiologists. Observing colony morphology is a tool used by clinical ... a colony will have a characteristic shape (both in elevation and margin), size, color, and consistency. Observation WebColony morphology is a method that scientists use to describe the characteristics of an individual colony of fungi growing on agar in a Petri dish. It can be used to help to identify them. Colony morphology. A circular piece of bread that has been allowed to go mouldy.
