摘要:

本研究将Oxyrase酶加入到接种了大肠杆菌O157:H7的培养基中以促进这种兼性厌氧微生物的生长。与不加Oxyrase酶的对照组相比,添加了Oxyrase酶的培养基中的大肠杆菌O157:H7的浓度明显提高。实验结果表明,Oxyrase酶在大肠杆菌O157:H7 快速培养中具有潜在的利用价值。

关键词: Oxyrase酶, 兼性厌氧微生物, 大肠杆菌O157:H7

Abstract:

In this study, oxyrase was added into broth that was inoculated with Escherichia coli O157:H7 to accelerate the growth of this facultative anaerobic microorganism. It was found that the Escherichia coli O157:H7 concentration in the broth added with oxyrase is much more than that of control (no oxyrase added), indicating that oxyrase has certain potential application value for rapid detection of Escherichia coli O157:H7.

Key words: oxyrase, facultative anaerobic microorganism, Escherichia coli O157:H7
