Phosphatase enzyme activity of phosphate solubilizing bacteria - Murugan Karuppasamy - Bog

Short Sketch About BookThis book of study reveals that twenty five isolates were recovered as phosphate solubilizing bacteria (PSB) from rhizosphere soil of paddy plants from four different locations of paddy field in Alwarkurichi village of Tenkasi District. Phosphate solubilizing bacterial population ranged from 30-50 × 102 CFU/g in Pikovskayäs agar medium, 20-30 × 102 CFU/g in hydroxy apatite agar medium and 10-20 × 102 CFU/g in soil extract agar medium. Among the tested isolates, highest load of phosphate solubilizers were found as the best in solubilizing phosphate 102 dilutions with the drop in neutral pH in Pikovskayäs agar medium. The results indicated that the rhizosphere soils of the study area inhabit phosphate solubilizing bacteria with great potential to be used as the commercial production of phosphatase enzymes. This study examines the effect of herbicide, one-shot on phosphate solubilizing bacterial activities like phosphate solubilization by herbicide resistance pattern. Here, the selected herbicide, one-shot was applied at two different concentrations of 10 ppm and 50 ppm against the phosphate solubilizers of Micrococcus sp., Bacillus sp. and Pseudomonas sp.
