摘要: The effects of particlesize and heating temperature magnesium oxide (MgO), calcium (CaO), zinc (ZnO) powders on the antibacterial activities their slurries were studied by conductance method. An increase in particle size reduced activity. variation activity against Staphylococcus aureus was smaller than that Escherichia coli, Salmonella typhimurium, Bacillus subtilis. This difference depended shape bacteria, but not character, such as structure cell walls. these powder decreased with an powders. For ZnO slurry, decrease much larger those MgO CaO slurries. It suggested decreases concerned stabilization surface heated at high temperature.
