Isolation of phosphate solubilizing micoorganisms from rhizosphere of sugarcane

The rhizospheric soil of sugarcane was investigated for the study of phosphate solubilization by bacteria and fungi. In the present study the number of microorganism were isolated from the rhizosphere of sugarcane. Among this six microorganisms viz. Bacillus, Pseudomonas, Azotobacter, Arthrobacter, Penicillium and Mucor solubilize the inorganic phosphate. From the study it was observed that fungi viz.Penicillium and Mucor have more solubilizing activity than bacteria both quantitatively and qualitatively. Hence the application of biofertilizer prepared by above mention bacteria and fungi should be helpful to increase the amount of phosphate into the soil because these microoeganisms release acid in very minut quantity in phosphate solubilization.
