Isolation And Characterization Of Phosphate Solubilizing Bacteria (Psb) From Saline Soil Samples Of Three Taluka Village (Near To Coastal Village Area) Of Gir-Somnath District, Gujarat., India

Abstract

Abstract Phosphorus is very essential growth-limiting plant nutrient and it can affect the overall growth of plants by producing various key metabolic processes such as cell division, cell development, macromolecular biosynthesis, photosynthesis and respiration of plants approximately 95-99%  of phosphorus is present in the form of insoluble phosphates but plants cannot be easily utilize it directly its play an important biochemical role in energy storage, energy transfer, cell enlargement and several other biological important processes in the living plant. Unavailable/insoluble phosphate compounds can solubilize by organic acids and phosphatase enzymes which produced by plants and several microorganisms. Several group of soil micro flora was reported for Converting insoluble phosphorous to solubilize form so plants can easily absorb phosphorous. In present study we isolated Phosphate solubilizing bacteria from 10 different villages of three taluka of Gir-Somnath district Gujarat which are near to sea costal area and salinity affected. More than 34 PSB isolates from collected soil samples and above them best 20 isolates selected on their phosphate solubilizing activities. Qualitative and quantitative phosphate solubilizing activity studied with different pH, Salt and temperature of isolates, Isolates CH1 (Chorvad 1), PR2 (Prashanavada 2), SU4 (Sutrapada 4), SA15 (Sarakhadi 15) and KD18 (Kadodara 18) gave potent Phosphate Solubilizing activity with different pH, temperature and salt concentration.
