Soil microorganisms are capable of solubilizing insoluble soil phosphate to release soluble P and making it available to plants. The potential heavy metal tolerant fungi, WMzF10 was isolated from the maize fields of Warangal district, Telangana state. Solubilized (410μg/ml) of tricalcium phosphate under optimum conditions. WMzF10 showed its plant growth promoting potential by producing indole acetic acid (47μg/ml), which was further confirmed by enhanced growth of Chilli seedlings with seed vigor index (1140) when compared to uninoculated control seed vigor index (615). WMzF10 also solubilized TCP under Heavy metals stress such as lead, chromium, nickel and cadmium in concentration ranging from 100-400µg/ml. Solubilization of P shows decrease in pH of the medium. This potential isolate WMzF10 was identified as Aspergillus niger by ITS regions and sequence was deposited in the GenBank, under the accession number MN907460.
