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. Provide an application for enrichment and selec- tive media. um B is heat-resistant, the specimen could be heated before isolation. Dyes such as phenol red, eosin, or methylene blue are sometimes ineluded in differential BACKGROUND media. Products of bacterial metabolism can react with One of the major limitations of dilution techniques used to isolate bacteria is that organisms present in limited amounts may be diluted out on plates filled with dominant bacteria. For example, if the culture to be isolated has 1…
