Objective  To observe the recovery

proliferation and growth of Proteus Mirabilis (PM) and Pseudomonas Aeruginosa (PA) in a low frequency weak electric field (LFWEF).   Methods  Three plates with same germ in same culture medium were put in an incubator. One plate was stimulated by LFWEF directly

the second was closed to the field source

and the last one was comparatively far away from stimulating source. Bacterium’s recovery and proliferation

and the growing speed were observed in solid and  liquid culture medium respectively.   Results  In a field (repeat frequency 0.2-9.8 Hz

empty space 0%-100 %

intensity 0-100 μA)

the proliferation and growing speed was better and faster in the directly stimulated group and close to stimulated source group than in the group without LFWEF stimulation

but there was no obvious difference between the later and the far away group.   Conclusion  LFWEF exerts promoting effects to bacterium growth.
