1. Proper aseptic technique is crucial to ensuring growth of pure bacterial colonies. What is one experimental way you can test your practices to confirm that you are using proper aseptic technique?This could be done by having a control agar plate where sterile loop was used to streak the agar. If it grows bacterial colonies after some time, then aseptic technique was not successful. 2. In a laboratory setting, what are three ways you can properly sterilize culturing equipment? a. Dry hea...
