Antibacterial Assay of Secondary Metabolites Extracted from Endophytic Bacteria from Plectranthus Amboinicus

Abstract

Endophytic bacteria have been found in virtually every plant studied, where they colonize the internal tissues of their host plant. Literature survey revealed the occurrence 76 volatiles and 30 non-volatile compounds belonging to different classes of phytochemicals such as monoterpenoids, diterpenoids, triterpenoids, sesquiterpenoids, phenolics, flavonoids, esters, alcohols and aldehydes. Bacteria isolated from Plectranthus amboinicus have great potential pharmaceuticals properties. Preliminary phytochemical analysis endophytic bacteria isolated from Plectranthus amboinicus showed the presence of alkaloids, flavanoids, terpenoids, phenols, saponins, carbohydrates and protein. The antibacterial activity of Secondary metabolites extracted from Encophytic bacteria of P.amboinicus was assessed by well diffusion method with 20, 10, 05, 2.5 and 1.25 μg/ml were found to be having higher inhibition over the E.coli. Pseudomonas spp., And Klebsiella spp., Staphylococci spp., and Streptococci spp., selected for the study.
