7 Overview and Goals
Plate Streaking
Streaking bacteria on agar plates allows scientists to obtain isolated colonies of bacteria. An isolated colony provides up to 10^8 bacteria cells that are genetically identical. This is why we call them clones or refer to them as colonies. The medium we chose to streak out bacteria must provide the nutrients required for prolific organismal growth, and not all bacteria require the same nutrients. There are various types of media, and we will use BUG agar plates to grow your bacteria, which may or may not support your bacterium’s growth.
After completing this lab you will gain the following lab skills:
