Abstract

The methalonic and equeous extracts of ginger were employed in this investigation for antibacterial activity against both gram-negative (Escherichia coli) and gram-positive (Staphylococcus aureus). Agar disk diffusion was used to assess growth inhibition. The two extracts had clear antibacterial action against the microorganisms tested. In the growth of tested bacteria, the methalonic extract outperformed the equeous extract. The maximum zone of inhibition of methalonic extract in the development of S. aureus (16 mm) and the lowest zone of inhibition in the growth of E. coli (13 mm). The impact of equeous extract on the growth of two bacteria ranged between 10 mm in E. coli and 14 mm in S. aureus. Two extracts' antibacterial activity was compared to that of Gentamicin, a popular antibiotic (20 mm).
