In the present study ten endophytic bacteria were isolated from Paederia foetida and were subjected to antibacterial activity test. The maximum zone of inhibition was observed by the isolate PFNP2 against Staphylococcus aureus (17.6±0.5 mm) followed by Salmonella sp. (15.3±0.5 mm) and MRSA (14.6±0.5 mm). The bacterial isolate was identified as Staphylococcus haemolyticus by 16s rRNA gene sequencing with NCBI accession number PQ143273. Genes that are essential for the adaptation to the plants were mainly acquired by horizontal gene transfer which could explain the adaptation of such bacteria to plant environment. Presence of aromatic, aliphatic (C-H) and carboxylic acid (C=O) groups were detected in the ethyl acetate extract of the selected isolate by FTIR analysis. Bioactive compounds such as 2- Piperidinone, N- Hexadecanoic acid and Pyrrolo [1,2-a] pyrazine-1,4-dione, hexahydro-3-(phenylmethyl)- identified from the GC-MS mass spectra of the bacterial extract have been reported to have antimicrobial properties. This indicates that bacterial endophytes from Paederia foetida could be a source of antimicrobial compounds for use in biotechnological and pharmaceutical applications.
