Effect of Low-Voltage Static Electric Field on Growth of Bacillus sp.

Abstract:

Bacillus sp. was stimulated by external low-voltage static electric field of different intensity at the same time. To make comparisons of the biomass, pH, the metabolism of Bacillus sp.and the surface morphologies of Bacillus sp.treated and untreated. The results showed that when the electric field strength was between 0.5V/cm and 3V/cm, the pH was bigger in test group than control group. The growth of Bacillus sp. was inhibited at 3V/cm, and promoted at 0.5V/cm to 2.5V/cm. The growth of Bacillus sp. was promoted maximumly at 0.5V/cm. Finally, we find that low-voltage static electric field didn’t damage the morphology. The appropriate electric field strength can enhance the metabolism of Bacillus sp.
