Abstract

The Kewda essential oil (KEO) extracted from Pandanus odorifer male flower was evaluated for its phytochemical profiles, antimicrobial and anti-biofilm activities against Staphylococcus aureus and Klebsiella pneumoniae and their reference strains, MTCC 740 and MTCC 109 respectively. As evident from GC-MS analysis, the phytochemical profiles revealed the presence of 2-phenyl ethyl methyl ether (PEME) and Terpinen-4-ol as prominent secondary metabolites. The MIC of KEO was 5% (v/v) against all the test bacteria. The KEO exhibited strong antibacterial and anti-biofilm activities against test bacteria. A significant reduction in the biofilm production was observed with an inhibition of 67.51 ± 1.29% and 61.17 ± 3.75% against K. pneumoniae and 71.76 ± 4.56% and 59.3 ± 6.24% against S. aureus. The light and fluorescence microscopic analysis confirmed a significant decrease in the density and thickness of the biofilm matrix against both the clinical and reference strains when treated with sub-MIC of KEO.
