Nayomi John, M Thangavel

Abstract :

The variability of chemical composition and physical conditions in the oceans play a major role in the development of a great diversity of microbes.These distinctive characteristics have attracted many researchers to explore in depth since there is the potential of marine microorganisms used in industry. Plant growth promoting rhizobacteria (PGPR) is beneficial bacteria that colonize plant roots and enhance plant growth by wide variety of mechanism like phosphate solubilisation, etc. The present research work was designed to isolate and characterize the PGPR activity of marine bacteria. For this purpose bacterial isolates were isolated from the marine water and sediment samples and the efficient bacterial strain was screened for various parameters of plant growth promotion activities. Because of there PGP activities, bacteria were explored as bio-fertilizers to improve the soil fertility and plant growth and offers attractive way to replace chemical fertilizers, pesticides and other growth supplements.
