After this lab you should be able to:
- Observe sources of bacteria and fungi from the environment in, and around, the laboratory.
- Define the term ubiquitous.
- Describe some consequences of exposing your cultures to the air or non-sterile objects.
- Apply your observations to the practice of Aseptic Technique.
Microbes are ubiquitous. No doubt you’ve probably heard that by now in class or lab. In order for you to develop skills with aseptic technique, it helps for you to see this firsthand. What microbes are in the air? What microbes are found on the surfaces of things around you? We will continually stress the importance of protecting your cultures (and yourself and others) from contamination. This exercise will show you where sources of bacterial and fungal contamination can be found, and how common microbes are in our environment.
