Abstract
Palm wine was assessed for its antimicrobial property. The antimicrobial property was assayed on five
bacteria: Escherichia coli, Staphylococcus aureus, Proteus mirabilis, Pseudomonas aureginosa and a
Bacillus sp with one fungus Candida albicans. The minimum inhibitory concentration and the minimum
bactericidal concentration of palm wine on these organisms were determined using agar well diffusion
method. The antimicrobial activity on these organisms was then compared with the action of methylated
spirit, a known commercial disinfectant. Palm wine was found to be more active against the gram
negative organisms (Escherichia coli, Pseudomonas aeruginosa and Proteus mirabilis) than the gram
positive organisms (Bacillus sp and Staphylococcus aureus). The action was bactericidal on the gram
negative organisms while it was bacteristatic on the gram positive. It was found out that palm wine had
no inhibitory or cidal action on Candida albicans which is one of its resident organism. The
antimicrobial action was also found to compare favorably with methylated spirit a known commercial
disinfectant.
