Sterilization and antibacterial ability of nano magnesium oxide

Different amounts of magnesium oxide were dispersed on the carrier of infected bacteria tablets for different times, and the killing rate was calculated to evaluate the sterilization ability of magnesium oxide; different amounts of magnesium oxide mixed bacterial solution were placed in the shaker and shaken for different times, and the inhibition rate was calculated to evaluate the inhibition ability of magnesium oxide.

Nano magnesium oxide can effectively kill Escherichia coli, and also has a significant killing effect on Bacillus subtilis black var.

The nano-magnesium oxide has strong bactericidal effect and bacterial inhibition ability. The results of carrier quantitative killing test and oscillating flask test show that the nano-magnesium oxide powder has good inhibition and killing function for bacterial propagules such as Escherichia coli and Staphylococcus aureus, and also has certain killing effect for bacterium. Nano magnesium oxide can be used as an additive, added to some paint and coating or ceramic surface, used to sterilize or inhibit bacteria. It can also be used as a substitute for activated white clay in military personal disinfection kits for disinfection of biological warfare agents.
