	SOLID STATE CULTURING OF THERMOPHILIC FUNGI FOR PHYTASE PRODUCTION MUHAMMAD MOHSIN JAVED, WASEEM AHMED, SANA ZAHOOR AND IKRAM-UL-HAQ Abstract:* Seven different types of themophilic fungi such as Aspergillus fumigatus, Humicola insolens, Rhizomucor miehei-I & II, Sporotrichum thermophile, Thermomyces lanuginosus-I & II were isolated from the compost of various localities. Among all isolates, Sporotrichum thermophile was found to be the best isolate for the phytase production. Six different types of solid materials (wheat bran, rice bran, rice husk, fish meal, corn seed and corn gluten) were evaluated as growth substrate for phytase production by Sporotrichum thermophile. Of all the sources tested, wheat bran supplemented with diluent containing (g/L); (NH₄)₂SO₄;5.0, KH₂PO₄; 1.0, Yeast extract; 2.0 gave maximum production (4.16 U/mL/min) when 4% volume of the 250 mL conical flask was used after 96 hrs conidial inoculation at 45^oC using solid-state fermentation.
