项目摘要
To accurately control the denitrification processes, information on numbers of viable microbes in the denitrification processes is very important. Although some methods have been known for this purpose, a rapid and simple technique is absolutely nothing for counting viable denitrifying bacteria in the processes. In this study, we consider to apply 5-cyano-2,3-ditolyl-2-tetrazolium chloride (CTC) method. Several nirS and nirK-type denitrifying bacteria and activated sludge under denitrifying conditions are prepared, and CTC concentration, CTC reaction time and the concentration of nitrate respiration inhibitor are optimized. The results revealed that the optimum conditions were 0.2 mM CTC, 1 h of reaction time and 1 mM of nitrate respiration inhibitor. Under the optimum condition, the CTC method could detect more than 80% of viable denitrifying bacteria in pure cultures and activated sludge.
为了准确控制反硝化过程,反硝化过程中活微生物数量的信息非常重要。尽管已知一些用于此目的的方法,但是快速且简单的技术对于计数过程中存活的反硝化细菌来说绝对无济于事。在本研究中,我们考虑采用5-氰基-2,3-二甲苯基-2-氯化四唑(CTC)法。制备了几种nirS和nirK型反硝化细菌和反硝化条件下的活性污泥,并对CTC浓度、CTC反应时间和硝酸盐呼吸抑制剂浓度进行了优化。结果表明,最佳条件为0.2 mM CTC、1 h 反应时间和1 mM 硝酸盐呼吸抑制剂。在最佳条件下,CTC方法可以检测纯培养物和活性污泥中80%以上的活反硝化细菌。
