The antibacterial activity of ginger extracts in various solvents were tested for activity against six organisms, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Serracia sp., and Bacillus subtilis using the agar-gel diffusion method. The results obtained showed that petroleum ether extract showed highest antibacterial activity against B. subtilis while other extracts were also active but at less extent. The MIC of petroleum ether extract of ginger was found to be 25µg/mL. This study established the need for daily use of this product for medicinal purposes.
