ISOLATION AND SCREENING OF EFFICIENCY OF PHOSPHATE SOLUBILIZING MICROBES

Abstract

The soil in the identified saline was investigated for the study of phosphate solublization by fungi and bacteria. In the present study 107 samples were collected from saline affected area, among these samples, 33 (30.80%) samples showed the ability to solubilize the inorganic insoluble phosphate. From the study it was observed that the fungi viz; Aspergillius spp., Penicillium spp. and Fusarium spp. have the more solubilizing ability of inorganic insoluble phosphate than bacteria, viz; B.subtilis, and B.megatherium. Hence the application of biofertilizer prepared by above mentioned fungi should be helpful to reduce the salinity of soil by neutralization phenomenon, because these microorganisms release the acid in very minute quantity in phosphate Solubilization.
