Hebei Messi Biology Co., Ltd. stated that different amounts of magnesium oxide are dispersed on the bacteria-contaminated bacterial tablet carrier and placed for different times, and the killing rate is calculated to evaluate the sterilization ability of magnesium oxide; different amounts of magnesium oxide mixed bacterial liquid are placed Shake in a shaker for different times, and calculate its antibacterial rate to evaluate the antibacterial ability of magnesium oxide.
Nano-magnesium oxide can effectively kill Escherichia coli and also has a significant killing effect on Bacillus subtilis black variant spores; Nano-magnesium oxide has a good antibacterial effect on Staphylococcus aureus and Bacillus subtilis black variant spores; Nano-magnesium oxide’s Abrasiveness, alkalinity, oxidation, and electrostatic adsorption to microorganisms make it bacteriostatic and bactericidal.
Nanomagnesium oxide has strong bactericidal effect and antibacterial ability. The results of the carrier quantitative killing test and the shaking flask test show that the nano-magnesium oxide powder has a good inhibitory and killing effect on bacterial propagules such as Escherichia coli and Staphylococcus aureus, and also has a certain killing effect on spores. Nano-magnesium oxide can be used as an additive and added to some paints or ceramic surfaces to sterilize or inhibit bacteria. It can also be used as a substitute for activated clay in military personal disinfection kits for the disinfection of biological warfare agents.
