Phosphorus solubilization by some marine fungi

A. Araujo, J. DeSouza, A.A. Karande


Ten marine fungi were qualitatively screened for phosphorus solubilizing ability. The organisms were then tested quantitatively in liquid media containing tricalcium phosphate as a phosphorus source. The optimum pH for phosphorus solubilizing activity of fungi was from 6 to 6.5. An incubation period of 6 days was required for an appreciable quantity of phosphorus to be leached into the medium. A maximum amount of 18% phosphorus was obtained in the culture filtrate and about 54% phosphorus was found in the total cell mass with Penicillium funiculosum
