The nitrite formed from nitrogen dioxide (NO2) was oxidized more readily in soil that had been treated previously with the gas than in soil not so pre-exposed. The reaction was inhibited by 1.0 but not by 0.01 mM chlorate. The population of nitrite-oxidizing autotrophs estimated by the most-probable-number procedure was too small and often grew too late to account for oxidation of the nitrite generated from NO2. The reaction also proceeded in soil heated to 42° to 45°C or treated with 0.16 mM chlorate, although the countable autotrophs did not increase during the transformation or grew only late in the active period of nitrite oxidation. The data suggest that unknown populations are responsible for metabolism of the nitrite produced from NO2 entering soil.
二氧化氮(NO2)形成的亚硝酸盐在先前用该气体处理过的土壤中比未预先暴露的土壤更容易被氧化。该反应被 1.0mM 而不是 0.01mM 氯酸盐抑制。通过最可能数程序估计的亚硝酸盐氧化自养生物的种群太小,而且通常生长得太晚,无法解释从 NO2 产生的亚硝酸盐的氧化。该反应也在加热至 42°至 45°C 的土壤中或用 0.16mM 氯酸盐处理的土壤中进行,尽管在转化过程中不可计数的自养生物没有增加,或者仅在亚硝酸盐氧化的活跃期后期生长。这些数据表明,未知的种群负责代谢进入土壤的 NO2 产生的亚硝酸盐。
