Abstract:
We tested the antibacterial properties of a mix of minerals consisting mainly of sericite, talc, and halloysite from Korea. The preparation showed clear growth inhibition of the gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, and the gram-positive bacteria Staphylococcus aureus subsp. aureus, S. epidermidis, and Bacillus cereus, as well as the anaerobic bacterium Propionibacterium acnes. These results indicate that this preparation, made from ore minerals indigenous to Korea, could be used to develop new antibacterial reagents.
