ANTIMICROBIAL ACTIVITY OF CYMBOPOGON

ABSTRACT
To discover the antimicrobial activity of the extract of Cimbopogon schoenantus was the primary interest of this dissertation. So, using ten selected microorganisms such as: I Gram-positive bacteria: Staphylococcus aureus, ATCC 29213; b. Streptococcus pyogenes, Group A; c. Streptococcus agalactiae, Group B, ATCC 12386; d. Enterococcus faecalis, ATCC 29212; e. Listeria monocytogenes; and II Gram Negative Bacteria: f. Escherichia coli, ATCC 35218; g. Shigella sonnei, ATCC 25931; h. Pseudomonas aeruginosa, ATCC 27853; i. Proteus mirabilis; and j. Serratia marcescens, an in-vitro experiment was performed to determine the size of zone of inhibition, the concentration that inhibits growth, and the time at which the microorganisms are killed.

Subsequently, the susceptibility of the active ingredients of Cimbopogon schoenantus extracts at different concentrations was compared with selected antibiotics using the same strains of microorganisms, and the chemical constituents of the plant extract yielding the active ingredients was identified using paper chromatography.
