Document from the year 2014 in the subject Biology - Miscellaneous, grade: B, , language: English, abstract: There are considerable evidences that support the specific role of phosphate solubilization in the enhancement of plant growth by phosphate solubilizing microorganisms. In this regard i had isolated a bacterial stain which could solubilize phosphate to a considerable level, hence i selected the organism and subjected it to further studies involving different parameters.Phosphate solubilizing microorganisms include bacteria and fungi which convert insoluble inorganic phosphatic compounds...
Document from the year 2014 in the subject Biology - Miscellaneous, grade: B, , language: English, abstract: There are considerable evidences that support the specific role of phosphate solubilization in the enhancement of plant growth by phosphate solubilizing microorganisms. In this regard i had isolated a bacterial stain which could solubilize phosphate to a considerable level, hence i selected the organism and subjected it to further studies involving different parameters.Phosphate solubilizing microorganisms include bacteria and fungi which convert insoluble inorganic phosphatic compounds into soluble form. The species of Pseudomonas, Micrococcus, Bacillus, Bradyrhizobium, Agrobacterium, Rhizobium, Flavobacterium, Penicillium, Fusarium, Sclerotium, Aspergillus,Curvularia,Mucor and others have been reported to be active in bio-conversion. Such bacteria and fungi can grow in media where calcium phosphate, iron phosphate, aluminium phosphate,apatite, bone meal, rock phosphate or similar insoluble compounds are the sole source of phosphate. Besides bacteria and fungi, mycorrhizal fungus like Glomus fasciculatum has also been studied for its capacity to solubilize insoluble phosphates. When PGPRs are used as fertilizers they express their multifunctional roles and benefit inoculated crops by providing crop with solubilized phosphate, by fixing nitrogen and by supplementing plant growth regulators and also involve in effective recycling of waste.
