Abstract

Syzygium aromaticum (clove), able to inhibit bacterial growth through disruption of the bacterial cell membrane. S. aromaticum flower bud were analyzed by methanol extraction and tested against 19 samples of V.. cholerae. The susceptibility of V. cholerae towards S. aromaticum extract evaluated using disk diffusion method showed the best zone diameter of inhibition of 12.667 mm at 100 mg/ml concentration. The MBECso of V. cholerae ranged 12.5 between 25.0 mg/ml while MBEC9o is 50.0 mg/ml extract concentration. Morphology change of V. cholerae observed through scanning electron microscope (SEM) for every treatment showed disruption of cell membrane. Thus in this study, S. aromaticum bud extract can be considered as potential antimicrobial agent against single cells of V. cholerae and able to prevent formation of V. cholerae in biofilm thus act as antibiofilm.
