细菌放射测量法是利用放射性核素监测细菌生长、代谢的技术。它是通过细菌对含有放射性标记的底物代谢降解为带有放射性的气体,经收集后探测其放射性的多少,以了解细菌的存在和生长、代谢的信息。大多情况使用~(14)C标记的营养物(如葡萄糖、氨基酸等),检测释放的~(14)CO_2气体,用以观察细菌生长、代谢规律。这种技术具有快速、敏感和客观的特点,目前已被广泛的应用,可做为细菌的定量测量和细菌的快速检验。 Bacterial radiometry is the use of radionuclides to monitor bacterial growth and metabolism. It is through the bacteria on the radioactively labeled substrate metabolized into radioactive gas, after the collection of radioactivity to detect how much to understand the existence and growth of bacteria, metabolism information. In most cases, ~ (14) C-labeled nutrients (such as glucose, amino acids, etc.) were used to detect the release of ~ (14) CO_2 gas for observation of bacterial growth and metabolism. This technique is fast, sensitive and objective and has been used extensively as a quantitative measure of bacteria and as a rapid test of bacteria.
