In Vitro Use Guide

175 mM of potassium myristate was inoculated with a bacterial suspension (3.0 × 10^7 spores/ml), and cultured for 10 days at 37℃. No growth was apparent in potassium myristate salt-bacteria cultures even after 10 days. This suggests that the antibacterial activity of potassium myristate is long-lasting.
