Isolation of marine bacteria from polychaete species and their antibacterial activity in uppanar estuary, southeast coast of india

Abstract

Background/Objectives: The marine surface linked with microorganisms have demonstrate to be a fertile source for
innovative bioactivities due to the requirement to expand allelo-chemicals which is able to secure the producer from the
intense competition which exists among the microorganisms on the surface of marine eukaryotes.
Methods/statistical analysis: Polychaetes were collected from the Uppanar estuary and bacteria isolated from them. From
the isolated bacteria were used for antibacterial activity.
Findings: Polychaetes related with bacterial density were monitored for a time of one year. The ranged of bacterial
density1.8 x 105
and 6.0 x 105 CFU/g in monsoon and summer seasons. 15 strains were tested, among them, 12 strains
showed inhibitory activity against Staphylococcus aureus, 11 strains against Klebsiella pneumonia, 10 strains against
Pseudomonas aeruginosa and 15 strains against E.coli.
Application: The huge capability of marine organisms as a supplementary of bioactive metabolites that might be directly
applied as a medication or fill in as lead molecules for medication progress. The invention of new classes of antibiotics is
vital because of the expanded occurrence of various obstructions between pathogenic microorganisms to medication that
are as of now in clinical use.
Hence, the present has been proven to produce the antibacterial bacteria from marine polychaete species.
