Phosphate-solubilizing bacteria (PSB) function in soil phosphorus cycle, increasing the bio-availability of soil phosphorus for plants. Phosphate solubilizing microorganisms (PSMs) offer an ecologically acceptable mean for converting insoluble phosphate to soluble forms making them available for plants to absorb. Several bacterial strains (Pseudomonas, Bacillus, Rhizobium and Enterobacter) and fungal strains (Aspergillus and Penicillium) have so far been recognized as powerful phosphate solubilizers. Bioremediation is the application of biological systems to the clean-up of organic and inorganic pollution, with bacteria and fungi being the most important organisms for reclamation, immobilization or detoxification of metallic and radionuclide pollutants. Study clearly demonstrated phosphate solubilizing bacteria can play an essential role in bioremediation of pollutants and increased more NP content in plants and enhanced the available P in soil. This characteristic stimulates the use of alternative biotechnologies, due to their reduced cost and lower aggressiveness to the environment. The ubiquity and importance of microbes in biosphere processes make geomicrobiology one of the most important concepts within microbiology, and one requiring an interdisciplinary approach to define environmental and applied significance and underpin exploitation in biotechnology.
