For example, if bacterium B is salt-tolerant, a high concentration (>5%) of salt could be added to the culture medium. Physical conditions can also be used to select for a bacterium. If bacteri- After completing this exercise, you should be able to: 1. Differentiate selective from differential media. 2.
