The process of milk decomposition from a community of bacteria can test the same processes and theories in a much more reasonable time frame.

It is a process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance.

Describe the changing sequence of organisms and corresponding environmental changes during succession in the milk samples. Propose another experiment to test the environmental factors and/or organisms changing in your proposed scenario for milk succession. Infer what the change in pH means about the populations of microorganisms in the milk.

If the bacteria is Gram positive, it will retain the primary stain (crystal violet) and not take the secondary stain (safranin), causing it to look violet/purple under a microscope.
