Abstract

<i>Pseudomonas corrugata, </i>a soil isolate, initially obtained from a temperate location in Sikkim (Himalaya), was examined for its tricalcium phosphate solubilizing ability along a wide temperature range, from psychrophillic to mesophillic. The phosphate solubilization, by indirect petridish assay, was in conformity with the results of direct estimation of phosphate solubilization in broth. While the maximum solubilization was found to occur at 21°C, the bacteria solubilized more phosphate at 4°C than at 28°C. The species showed affinity towards lower temperature range. The study has implications for developing carrier-based microbial inoculants for improved growth of plants in the mountains.
