Phosphate solubilisation efficacies of four bacterial and four fungal isolates were tested on
different media after isolating from the soils of Lahaul and Spiti valleys. Amongest bacterial
isolates, HBP1 and in fungal isolates, HFP1, represented appreciate solubilisation of TCP followed
by MRP and URP and represented maximum fall in pH of filterate in NBRIP broth. The HBP1
solubilised maximum TCP at pH 9 and HFP1 at pH 5. Moreover, HBP1 proved to be the most
efficient strain in solubilizing TCP in the presence of 2.5% w/v NaCl. HFP1 fungal isolate
represented highest potential to solubilize TCP in control than all other concentrations. The HBP1
and HFP1 solubilised maximum P at 24oC temperatures.
