Influence of Magnetic Field on Antibacterial Effect of Extracts from Black Pepper

Abstract:

In order to investigate the effect of magnetic field on the antibacterial substances from black pepper, we used shaking and ultrasonic-assisted ethanol extraction with Escherichia coli, Staphylococcus aureus, Bacillus anthracis and Aspergillus niger as indicator bacteria respectively. Meanwhile, extraction rate and diameter of inhibition zone were regarded as the activity monitoring parameters. The results showed the existence of magnetic field can make a difference. It weakened the antibacterial activity of black pepper by shaking extraction. However, the antibacterial activity of substances to Aspergillus niger was proportional to the intensity of the applied magnetic field by ultrasonic-assisted ethanol extraction.
