Note: Growth of bacteria in the following media:
Broths –indicated by turbidity or cloudiness, Solid media – such as slants allow for visible
growth on the surface that can be observed foe color and texture.
Plates allow for isolated colony growth, where one species could be separated from
another if colonies are isolated and sub cultured.
7. How is disinfectant used on your work surface?
8. How is a culture transferred from a broth to an agar plate
