Solutions were incubated at 37 o C for 7 hours and centrifuged at 2500 rpm. Pellets were resuspended in PBS at a pH of 7 and OD600 was recorded to compare MRSA growth. Supernatant fluid was incubated with nitrocefin at a concentration of 500 µg/mL for 45 minutes and color changes were analyzed via ImageJ software.
