Isolation, Identification and Phenotypic Characterization of Fluorescent Pseudomonas sp. isolated from the Replant site of Apple and Pear orchards

Fluorescent pseudomonads (FP), a major component of rhizobacteria, promote the plant growth through their multifarious activities. In the present investigations, 29 isolates of fluorescent pseudomonads isolated from the rhizosphere soils of replant site of apple and pear were isolated and identified by phenotypic i.e., morphological physiological and biochemical methods. The results indicated that most of the isolates tested were gram negative, non spore producing, coccobacillus in shape, catalase and oxidase positive and also fluorescent pigment belonging to genus Pseudomonas. These isolates can be used as potential biofertilizers and also as biocontrol agents.
