中文摘要：

病原体微生物在象处理设备的奶店那样的各种各样的环境存在。他们容易没被消除，并且显著地涨细菌感染的风险。一种新奇类型的抑制能力 304 忍受 Cu 不锈钢(304CuSS ) 与缩放 nano Cu 富有对葡萄球菌 aureus 猛抛(S。aureus ) 并且 Pseudomonas aeruginosa (P。aeruginosa ) 增加的整个牛奶在这研究被调查。结果证明在 24  h 接触以后，抑制对 S 304CuSS 评价。aureus 和 P。aeruginosa 补充说分别地，整个牛奶与 304SS 在对比到达了 99.2% ± 0.3% 和 99.3% ± 0.2% 。在平凡整个牛奶， 304CuSS 的抑制率也与 304SS 相比到达了 66.9% ± 2.0% 。结果证明 304CuSS 杀死了 planktonic 细菌的多数，并且有或没有细菌增加在整个牛奶禁止了无柄的细菌坚持到钢表面，显著地减少细菌的生长率。这些研究结果明确地证明在奶店的这新奇抗菌剂不锈钢的一个申请潜力联系了食物工业。

英文摘要：

Pathogen microorganisms exist in various environments such as dairy processing facilities. They are not easily eliminated, and significantly raise the risk of bacterial contamination. The inhibition ability of a novel type 304 Cu-bearing stainless steel （304CUSS） with nano-sized Cu-rich precipitates against Staph-ylococcus aureus （S. aureus） and Pseudomonas aeruginosa （P. aeruginosa） added whole milk was investigated in this study. The results showed that after 24 h contact, the inhibition rates of the 304CUSS against S. aureus and P. aeruginosa added whole milk reached 99.2% ± 0.3% and 99.3% ± 0.2%, respectively, in contrast with the 304SS. In the plain whole milk, the inhibition rate of the 304CUSS also reached 66.9% ± 2.0% compared with the 304SS. The results demonstrated that the 304CUSS killed majority of the planktonic bacteria, and inhibited sessile bacteria adherence to the steel surface in the whole milk with and without bacteria addition, significantly reducing the bacterial growth rate. These research outcomes explicitly show an application potential of this novel antibacterial stainless steel in the dairy related food industry.
