摘　　要：为明确磁处理水对苏云金芽孢杆菌生长的影响,用恒定磁场处理的磁化水配制液体培养基进行苏云金芽孢杆菌菌株的培养,结果表明,在28~50 Gs磁场强度处理水可以提高G-02菌株的产孢量,G-02在43 Gs磁场强度处理水配制的培养基中产孢量最大,达到6.1×108孢子/mL,比对照提高了11%;在7~43 Gs磁场强度内处理水可以提高HD-1菌株的产孢量,HD-1磁场强度处理水配制的培养基中在14 Gs产孢量最大,达到6×108孢子/mL,比对照提高了28%。在43 Gs处理2~12 h的磁处理水可以提高G-02菌株的产孢量,而在14 Gs处理2~14 h的磁处理水可以提高HD-1菌株的产孢量。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 28-50 Gs magnetic intensity ,and the maximum capacity of sporulation was up to 6.1 ×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 wa-ter treated using 7-43 Gs magnetic intensity ,and the maximum capacity of sporulation was up to 6 ×108 spore/mL in the broth with 14 Gs treated water , which was 28% higher than control .The sporulation capacity of G-02 and HD-1 were also improved in the 43 Gs 2-12 h treated water and the 14 Gs 2-14 h treated water respectively .
