Culturing bacteria

How do these media differ?

What component(s) of these media will bacteria use for their carbon and energy sources?

Growth patterns in broth cultures

What is the advantage of a pellicle?

Look at pigments and growth patterns.
It is important to learn to recognize that bacteria differ in their appearance on the same medium. These differences include:

1. Whether the bacterium grew.

2. The appearance of the growth.

3. Whether the bacterium has a pigment.

The plate at the left was inoculated with three different bacteria.

Do any of three organisms growing on this plate produce a pigment?

Did all three bacterial species grow?
