细菌放射呼吸测量研究中的一个技术关键问题就是既要为多种细菌提供生长繁殖所需的良好营养条件,又要有合适的~(14)C标记底物供细菌代谢降解生成有放射性的~(14)CO_2。国外研制出不同型号的放射测量用的培基商品(如需氧菌用的6B,厌氧菌用的7B等)。现将我们比较几种需氧菌培基的放射测量效果与细菌生长浓度的结果报告如下。
One of the key technical issues in the study of bacterial emission respiration measurement is that it not only provides the good nutrition required for growth and reproduction of many kinds of bacteria, but also has a suitable ~ (14) C-labeled substrate for metabolic degradation by bacteria to generate radioactive ~ (14) CO_2. Foreign countries have developed different types of radiometric Pei-based products (such as the need for oxygen bacteria 6B, 7B for anaerobic bacteria, etc.). Now we compare several aerobic bacteria test results of radiometry and bacterial growth concentration results are reported below.
