Comparative Studies of Cultural Conditions and Characteristics of Endophyte from Nodules of Casuarina

Two strains of Frankia 86001 and 86002,were isolated from Casuarina eqvisetifolia.Their optimum cultural conditions for growth were tested.The results showed that the optimum medium for Frankia 86001 and 86002 was Bap;the optimum carbon source sodium propionate;the optimum nitrogen source casamino acids and NH4Cl for Frankia 86001 while for Frankia 86002 it was casamino acids and beef extract.The pH range was similar for both two Frankia strains.The media containing NaCl can promote growth of Frankia 86001 and Frankia 86002.
