A lab experiment was conducted at the department of microbiology, G. B. Pant University of Agriculture & technology, Pantnagar. MPS activities were measured in liquid media (NBRIP broth) using Ammonium sulphate as N source, glucose and maltose as a carbon source at 10oC. Glucose significantly increased MPS activity and this activity was three times () in comparison of maltose (). The mineral phosphate solubilizing activity was strongly associated with the production of gluconic or citric acids. Moreover, isolate (Enterobacter hormachei), maximum ‘P’ solibilization was observed on 7 th day of incubation at 10oC as compared to 30oC, when glucose is taken as a carbon source and Ammonium sulphate (NH4)2SO4 as nitrogen source. | Role of different carbon source on phosphate solubilization by psychrotolerant isolate
