abstract：:The study was made of the antibacterial effects of three terpene alcohols on Staphylococcus aureus, focusing on the leakage of K+ ions and toxicity over time. The leakage of K+ ions was monitored continuously with a K+-electrode. Our results suggested that the terpene alcohols, namely, farnesol, nerolidol and plaunoto...
