98 points : ) explain what the zone of inhibition is and how it works with bacteria and/or antibiotics.

Hey there!

Zone of Inhibition Testing is a fast, qualitative means to measure the ability of an antimicrobial agent to inhibit the growth of microorganisms. In the world of antimicrobial substances/surfaces, the degree to which these materials are inhibitory can be of vital importance to the health of the consumer. This test is a qualitative way for people to test the inhibition levels of their substances

Hope this helped, have a great day :)

Zones of inhibition can be seen when growing bacteria in an agar plate. When you add antibiotics to the bacteria you might see, (after a few days) a zone of inhibition around the samples of bacteria.

A zone of inhibition is simply the area around the bacteria where bacteria has not grown. This is due to a piece of wafer coated in antibiotics inhibiting the growth of the bacteria.
