BIOS 242 Week 1 Assignment; Lab 2 of 14 Onsite - Isolation of Pure Cultures Lab 2: Techniques for Isolation of Pure Cultures Learning Objectives: Isolate pure cultures from a mixed population of microorganisms using aseptic technique. Learn the streak plate method Introduction: Microorganisms exist in nature as mixed populations of different species. In order to study them and observe their characteristics it is first necessary to obtain pure cultures (a culture ...
