Effects and analysis of magnetic treatment on the amount of polysaccharides secreted by Bacillus spp.

Abstract

Bacillus spp. were cultured in a magnetic field environment using a fluid or liquid culture medium to investigate the effect of magnetic treatment on the amount of polysaccharides secreted by Bacillus spp. Most Bacilli belong to the genus Bacillus, a general term used to describe a group of aerobic or facultative anaerobic, spore-producing gram-positive bacteria, bacteria that can produce peptides, proteins, enzymes, functional polysaccharides, and other metabolically active substances. Bacillus extracellular polysaccharides have been shown to have antioxidant properties, immune activity, and antitumor properties, and the extracellular polysaccharides metabolized by Bacillus used in this experiment can repair skin damage caused by UV light. The effects of magnetic treatment on both the growth activity and cell membrane permeability of Bacillus spp. were experimentally explored to investigate the reasons for magnetic treatment to increase the amount of extracellular polysaccharides. The results showed that the medium-intensity magnetic field could improve the growth activity of Bacillus while increasing the expression ploidy of Bacillus surface membrane proteins, enhancing membrane permeability, and increasing the production of extracellular polysaccharide metabolism.
