Abstract:
Fungal strains were recorded by using dilution plate methods on pikovskaya's medium from Soil samples were collected from different localities in paddy growing part of Vidarbha region, Maharashtra India. Aspergillus spp. the most important genera isolated during this investigation. Phosphate solubilizing fungi (psf) were selected by formation of halo zone around fungal colony on (pvk) agar plate after 4 days of incubation. psf were identified morphologically. All isolates exhibit different levels of phosphate solubilizing activity on (pvk) broth medium containing tricalcium phosphate (TCP) as sole phosphorus source. Final ph of the medium solubilize and recorded. Aspergillus niger and Aspergillus flavus variable and Aspergillus niger- 1 showed Solubilization potential or activity 4.77, 4.00 and 3.00 mm clear zone on 3.5 and 7 days after incubation respectively whereas the ph values of the culture filtrates were 3.50 and 3.10 after 8 and 15 days of incubation in pikovskayas broth medium respectively.
