This study was focusedto isolate the Plant growth promoting bacteria (PGPB)such as Azotobacter spp, Pseudomonas spp, Rhizobium spp, and Phosphate solublizing bacteria from various samples. In this study, microorganisms were isolated from rhizospheric soil, non-rhizospheric soil and from the root nodules of leguminous plants.From the present study we can conclude that rhizosphere, non-rhizosphere and root nodular bacteria are able to produce Indole Acetic Acid (IAA), Gibberellic Acid (GA), Ammonia and Siderophore. All the four species of microorganisms were capable of producing phytohormones such as IAA, GA and growth promoting substances like Siderophore and Ammonia are able solublize phosphate in varied concentrations.<#LINE#>Hardoim P.R., Van Overbeek L.S., Berg G., Pirttil&auml; A.M., Compant S., Campisano A. and Sessitsch A.

A total of 48 isolates were cultivated using various media. Out of these isolates 25 were Gram-positive, 19 Gram-negative and 4 were Gram variable. Based on the metabolic activity of these isolates, 29 could produce catalase, 45, 47 and 24 utilized casein, starch, and citrate respectively. 22 produced H2S by sulphate reduction. Sugar utilization varied in all the isolates. Diversity indices such as Simpson, Shanon, Menhinick and Margalef index were also studied based on their metabolic activity. 25 well isolated purified colonies were selected for molecular analysis. Based on this study the identified isolates belonged to genera Bacillus, Brevibacillus, Geobacillus, Anoxybacillus and Brevibacterium. All these isolates may have potential biotechnological and industrial application.<#LINE#>Adiguzel A., Ozkan H., Baris O., Inan K., Gulluce M. and Sahin F.
