摘要

The objective of the present investigation work is to characterize the potassium solubilizing efficiency of Pseudomonas putida (VKSB 12) isolated from tea plantation soil. Soil sample was collected from tea plantation soil at Valparai region. The soil sample was subjected to isolate the indigenous potassium solubilizing bacteria using Aleksondrove medium. The solubilization efficiency of P.putida was studied critically using various sources of potassium mineral in vitro. The isolates were tested for its potassium solubilizing ability in the basal (Aleksandrov) medium supplemented with different potassium sources at 0.2% concentration muriate of potash (MOP), sulphate of potash (SOP) and Montmorillonite (standard K source). The diameters of the clearing zones around the colonies were measured for studying its solubilizing efficiency. Glucose is the main carbon source and maximal solubilization of MOP was found to efficient at 0.25%. Similarly, ammonium sulphate was found to be the best nitrogen source for potassium source solubilization at the temperature of 25°C.
