what?
Your Answer:
Zones of Inhibition
Zones of Inhibition
Question 4 pts
Why was an LB agar plate used to test the Staph culture as opposed to a
selective/differential agar that only grows Staph?
Your Answer:
LB agar is used as it simply provides the nutritional requirements to
encourage bacterial growth. Since the results of the Kirby Bauer method
is directly based on bacterial growth patterns, no other selective or
differential additives should be present that may hinder or inhibit the
samples growth.
