The ecological importance of heterotrophic nitrification has been difficult to assess because of low levels of nitrification associated with this phenomenon. Nitrification by a soil isolate, an Alcaligenes sp., which oxidizes pyruvic oxime to produce up to 1867 mg nitrite-nitrogen/L, is described. Sequential nitrification with the chemoautotroph Nitrobacter agilis, ATCC 14123, resulted in nitrate accumulation and a concomitant decrease of the nitrite produced by the Alcaligenes sp. when the bacteria were jointly cultured. The ecological significance of such a sequential system is discussed.
由于与异养硝化作用相关的硝化水平较低，其生态重要性一直难以评估。本文描述了一种土壤分离菌——产碱菌属（Alcaligenes sp.）的硝化作用，该菌可将丙酮酸肟氧化，产生高达1867毫克亚硝酸盐氮/升。当与化能自养型的活跃硝化杆菌（Nitrobacter agilis）ATCC 14123联合培养时，该产碱菌属产生的亚硝酸盐会伴随硝酸盐积累而减少。本文还讨论了这种顺序系统的生态意义。
