硒的热化学研究 Ⅱ . Na_2SeO_3 对产气杆菌的作用特征

Thermochemical Studies of Selenium Ⅱ. Characteristics of Action of Na 2SeO 3 on Aerobacter Aerogenes

用微量热法研究了Ｎａ２ＳｅＯ３对产气杆菌的作用特征，得到了产气杆菌生长代谢过程中速率常数随Ｎａ２ＳｅＯ３浓度变化的关系式，以及最大发热功率与速率常数之间的关系式．实验表明，在高浓度时硒对产气杆菌有很强的抑制作用，为揭示硒的生物效应、研究硒的药理学和毒理学等提供了丰富的信息．

The characteristics of the action of Na 2SeO 3 on Aerobacter aerogenes has been studied by means of microcalorimetry.The relationship between growth rate constants k and the concentration C of Na 2SeO 3 is inverstigated.It is found that Na 2SeO 3 has obvious inhibitory action on aerobacter aerogenes,and the relationship between growth rate constants k and maxium metabolic thermogenesis power P max  is also reached.It has provided a lot of information on the bioaffect of selenium and the research of toxicology.
