Phosphorous is considered as a major parameter for crop yield. Its availability to plant is independent of its abundance. For the plants to utilize phosphorous, it is to be converted to absorbable form. Here, the part rendered by phosphate solubilizing bacteria is significant for it plays a crucial role in the formation of plant usable phosphate from organic forms. In the present work, an effort had been made to isolate and identify phosphate solubilising bacterial isolate from the rhizhospheric soils of various plants in Ponthenpuzha forest. One of the isolate from Cymbopogon citrates responded positively to Pikovskaya’s medium by producing a halo zone during in vitro culture. Colony features and 16S rRNA sequence analysis identified the isolate as Burkholderia sps. We have reported the presence of genus Burkholderia in the rhizospheric zone of Cymbopogon citratus. Further studies are warranted for species level identification of the isolate.

Phosphate Solubilizing

Phosphorus (P) is one of the essential macronutrients needed for the plant growth, other than nitrogen and potassium. Most phosphorus remains as insoluble form in soils and the plants only can uptake the phosphorus nutrient in soluble forms. Phosphate solubilizing bacteria (PSB) dissolves the phosphorus and make it available for plants. In this study, Soil samples were collected and screened for PSB on PK medium. PSB colonies with the highest phosphate solubilization ability were chosen and used for studying its rhizosphere effect on Capsicum frutescens by pot experiment.. It was evidenced that selected PSB strain could solubilize phosphate in PK medium and modified PK broth. Besides, it provided available phosphorus for plants and enhanced the plant growth in pot experiment.
