【摘要】 同一均匀磁场用不同处理时间和方式对黑曲霉（Asperillusniger）生长有不同的影响。磁场处理对其早期（0～24h）生长表现为抑制作用。当培养48h时．静置处理对其生长表现为良好的促进作用，振荡处理表现为抑制作用。静量处理1h时GSase比活力提高64.40％。更多还原

【Abstract】 Different effects of the same magnetic field on the growth of Asperillus niger can be foundby using different time and different manner. The early growth (0～24h) of Asperillus niger was inhibited bytreatment of magnetic-field. When shake culture for 48h,its growth increased markedly with treatment of stati-onary msanetic-field but was inhibited by treatment of motive magnetic-field. The specific acivity of GSaseincreased by percent 64. 40 by the tteatment of stationary magnetic-field for one hour.更多还原
