Abstract: Bt G-02 and Bt HD-1 were cultured in the broth with the magnetic treated water respectively. The results indicated that the sporulation of G-02 and HD-1 strains were effected by the water treated using different magnetic intensity and different time. The sporulation of G-02 strain was improved in the water treated using the 28一50 Gs magnetic intensity , and the maximum capacity of sporulation was up to 6. 1 x 10⁸ spore/mL in the 43 Gs treated water, which increased 11%compared with control. The sporulation of HD-1 strain was improved in the water in treated using 7-43 Gs magnetic intensity } and the maximum capacity of sporulation was up to 6 x 10⁸ spore / mL in the both with 14 Gs treated water ,which was 28 % higher than control. The sporulation capacity of G-02 and the 14 Gs 2一14 h treated water respectively.
