Abstract
Various parts of banana have shown to have antimicrobial effect based on previous
study. Therefore, a comparative study on the antibacterial activity of the pulp extract
of three different banana species, namely Pisang Berangan (Musa acuminate
AA/AAA), Pisang Mas (Musa acuminate AA) and Pisang Nipah (Musa balbisiana
BBB) was conducted against selected organisms. The acetone, methanol and aqueous
solution of the banana extract were tested using agar disc diffusion method for
antimicrobial sensitivity testing. The solvent extraction data showed that acetone had
the highest mean of banana pulp extract yield (15.16), followed by methanol (13.73)
and aqueous solution (5.403). The bacteria isolates were Staphylococcus aureus,
Streptococcus mutans, Pseudomonas aeruginosa and Escherichia coli. The acetone
and methanol extracts of all banana types showed an average with almost similar
zone of inhibition activity at 10 mg/disc concentration against gram negative bacteria
{P. aeruginosa and E. coli) ranging between 7 mm to 8.5 mm, whereas aqueous
extract of all banana types did not show inhibitory action against tested organisms. In
conclusion, the results implied that the pulp extract of three different banana species
could be potential source of antimicrobial agents but further studies must be
undertaken to identify the bioactive components responsible for their antimicrobial
activity.
