Isolation and Identification of Soil-Derived Pseudomonas Species with Potential Plant Growth Promoting Traits

Microbial biofertilizers have proven to be a better substitute to the chemical fertilizers. Pseudomonas is a beneficial bacterium in enhancing growth of the plants. In this study, attempt was made to collect soil sample and isolate the pseudomonas strains, study their morphological, cultural characteristics. These isolates were subjected to various biochemical tests such as Indole Acetic Acid (IAA) Test, Triple-Sugar-Iron Test, etc., and out of nine isolates namely PF1,PF2,PF9 , PF2, PF7 and PF8 have yield maximum results and have shown a potential for their use as biofertilizers
