Abstract:

The determination of dehydrogenase activity ( DHA ) by using 2,3,5-tripheyltetrazolium ( TTC ) and p-iodonitrotetrazolium violet ( INT ) as artificial hydrogen-accepted body, and their advantages and disadvantages inreflecting microbial activity are introduced. The development of TTC-dehydrogenase activity determination is re-viewed. Its standard curve in the determination process of dehydrogenase activity by using TTC as hydrogen ac-cepted body is discussed particularly. A great many of influential factors, such as temperature, pH and extractantetc. are compared and analyzed. The best experimental conditions are confirmed. The application of this process to wastewater treatment, the chemical poisons and metallic poisons and soil pollution are summarized briefly.

Key words: dehydrogenase activity, 2, 3, 5-tripheyltetrazolium, p-iodonitrotetrazolium violet

摘要:

介绍了分别用 2, 3, 5- 氯化三苯基四氮唑( TTC )以及碘硝基四唑紫( INT )等作为人工受氢体进行脱氢酶活性( DHA )检测的几种常见方法,以及它们自身在反映微生物活性等方面的优缺点。 论述了 TTC 在 DHA 检测中的发展,重点讨论了 TTC 作为受氢体进行 DHA 测定过程中其标准曲线制作方法的改进,并对测定中诸多影响因素如温度、pH 及萃取剂等进行了比较分析,确定了最佳实验条件。 简要概括了目前 DHA 测定方法在废水生化处理、评价化学毒物和金属毒物的毒性、土壤污染等方面的应用。
