Abstract

Ultrafine bubbles (UFBs) are gaining attention in diverse industries as a new type of material with specific physical properties. Bactericidal activity has been reported as one of the unique properties of UFB water; however, the bactericidal activities of UFBs related to the gas type remain unclear. In particular, the bactericidal effect of hydrogen (H) -filled UFB water has not been verified. Therefore, this study aimed to evaluate the bactericidal effects of H- or ozone (O) -filled UFB water using a bacterial suspension test. The results of this study clearly showed that H- or O-filled UFB water had strong bactericidal activity. Exposure of Escherichia coli for 6 h and Staphylococcus aureus for 3 h reduced the survival rate of those bacteria by >90%. This finding suggests that both O gas- and H-filled UFBs are novel environmentally friendly disinfectants that can be employed to avoid the use of chemicals.

摘要

超细微气泡（UFB）作为一种具有特殊物理性质的新型材料，在各个行业引起了关注。已有报道称，UFB 水具有杀菌活性，是其独特性质之一；然而，UFB 相关的气体类型的杀菌活性尚不清楚。特别是，填充氢气（H）的 UFB 水的杀菌效果尚未得到验证。因此，本研究旨在使用细菌悬浮试验评估填充 H 或臭氧（O）的 UFB 水的杀菌效果。本研究结果清楚地表明，填充 H 或 O 的 UFB 水具有很强的杀菌活性。暴露于大肠杆菌 6 小时和金黄色葡萄球菌 3 小时，使这些细菌的存活率降低>90%。这一发现表明，O 气体和 H 填充 UFB 都是新型环保消毒剂，可以用来避免使用化学物质。
