Student Name: Ashley Anderson. Access Code (located on the underside of the lid of your lab kit): AC-VRIKUTP. Pre-Lab Questions 1. What is the difference between chemically defined and chemically complex media? Give either a clinical or environmental research example for which each media type would be the most appropriate choice for culturing microorganisms.

1. growth media nutrient-rich environment for isolating and culturing microorganisms - liquid or solid 2. LB media (lysogeny broth) Most common nutrient Broth Known for ability to grow vast array of microbes 3. Selective Media allows for growth of specific microbes, while restricting the growth of other microbes often used to grow human pathogens, or slower growing microbes. The selectivity allows for discounting foreign unwanted microbes 4. Differential Media allows growth of several...
