    Microbial solubilization of rock phosphate on media

    Aug 24 2006 Four agro-industrial wastes were assayed as substrates for microbial solubilization of rock phosphate RP. Sugar beet wastes SB olive cake OC and olive mill wastewaters OMWW were treated by Aspergillus niger and dry olive cake DOC was treated by Phanerochaete chrysosporium. In conditions of solid-state fermentation 46 of SB and 21 of OC were mineralized
