Isolation and Characterization of Pseudomonas fluorescens in the rice rhizospheric soils of Rangareddy district in Telangana state

Abstract

Rice is an economically important food crop, which is subjected to infection by fungal, viral and bacterial
pathogens. Plant growth-promoting rhizobacteria (PGPR) are beneficial bacteria that colonize plant roots and
enhance plant growth by a wide variety of mechanisms. The potential negative effect of chemical fertilizers on
the global environment and the cost associated with production had lead to research with the objective of
replacing chemical fertilizers with bacterial inoculants. Pseudomonas fluorescens is an important among PGPR
because it is having an ability to induce plant growth as well as control the growth of pathogens. Native
population of these rhizobacteria play an important role in the sustainable agriculture as they majorly dominate
the rhizosphere. In the present study thirty P. fluorescens isolates were isolated from the rhizosphere of rice
from the Rangareddy district, Telangana and characterized by morphological and biochemical tests.
