Photographs showing the antibacterial zone of inhibition (ZOI) and minimum inhibitory concentration (MIC) of J.Marshi and the standard meropenem against S. aureus.
The clear diameter around each well of the Petri plate indicated the ZOI in millimeters. Likewise, the MIC indicated the lowest concentration of test extract or standard antibiotic showing no bacterial growth on visualization (blue color) against the negative control (pink), confirming bacterial growth.
