*2.8. Antibacterial Activity of Cotton Fabrics*

The antibacterial activity of cotton fabrics treated with ACR and [Cu2(ACR)(NO3)2] was tested against *B. cereus* and *P. aeruginosa* as model strains. Test tubes containing MPB and square cotton specimens (10 mm × 10 mm) were inoculated with a suspension of each bacterial culture. Untreated cotton and without specimens were used as controls. After incubation for 24 h at the appropriate temperature, the bacterial growth was determined by measuring OD600. Antimicrobial activity of the treated cotton samples was evaluated by the reduction of OD600 after incubation compared to the control sample. All antimicrobial tests were done in triplicate, and the average was taken.
