Instructions: Except for one or two labs the following schedule of laboratory exercises can be found in the Lab Manual : "Selected Exercises from Microbes in Action by Seeley and Van Demark.
Students should read each exercise before coming to the lab. There may be a prelab quiz before the lab. The lab schedule is tentative and may be modified
