Embodiment Construction

[0036] The present invention selects Escherichia coli (ATCC25922) as the test strain, and takes the copper-containing ferritic antibacterial stainless steel developed by the Institute of Metal Research, Chinese Academy of Sciences as the test material. The antibacterial performance of copper-containing antibacterial stainless steel is indicated by the content of malondialdehyde after Escherichia coli interacts with various antibacterial samples and control samples. The compositions of antibacterial materials and control samples are shown in Table 1.

Abstract

A method for determining antibacterial ability of antibacterial stainless steel by utilizing TBA means includes determining content of final product-propane aldehyde by TBA means after unsaturated fatty acid in indication bacterial liquid is oxidized, utilizing said content of propane aldehyde to calculate out sterilization rate so as to evaluate out antibacterial ability of antibacterial stainless steel.

Description

Technical field: [0001] The present invention relates to two disciplines of biological science and material science, belongs to interdisciplinary field, and its specific content is to use thiobarbituric acid method (abbreviated TBA method) to measure the oxidized unsaturated fatty acid of bacterial cell membrane after the action of antibacterial stainless steel material Degree, and then calculate the method of antibacterial performance of different antibacterial stainless steel materials. Background technique: [0002] Antibacterial stainless steel is a new type of functional antibacterial material known as having cross-age significance. It has good mechanical and antibacterial properties and has a wide range of applications, especially in areas that emphasize antibacterial, such as food industry, medical equipment, kitchen and bathroom, etc., can be Play an effective and long-lasting role. The development and application of antibacterial stainless steel materials can not o...
