Application of jamun (Syzygium cumini Linn) seed extract on cotton fabric for antibacterial activity

Abstract

Attempts have been made to use jamun (<em>Syzygium c</em>umini Linn) seed extract on cotton fabric to evaluate its antibacterial activity against some Gram positive and Gram negative bacterial strains. Different concentrations of jamun extract (125, 250, 500 and 1000 mg / mL) have been used and zone of inhibition (ZOI) is measured. The findings indicate that jamun seed has an antibacterial effect on bleached cotton fabric at different bacterial strain of <em>Staphylococcus aureus </em>(NCIM 2079) and <em>Streptococcus agalactiae</em> (NCIM 2401). The antibacterial potential of jamun seed powder is due to the rich bioactive compounds. High inhibition percentage is obtained for 1000 mg/mL seed extract and minimum for 125 mg/mL. <em>Streptococcus agalactiae </em>(77% strain) shows the maximum 24 mm ZOI and <em>Staphylococcus aureus </em>(55% strain) shows 18 mm ZOI.
