Nitrite oxidizing bacteria (NOB) that inhabit the whole environment extensively are bacterial species that are in charge of the latter part of nitrification. But little strains of them are isolated as pure culture. This study were carried out for exploration and its application of useful of genetic resources and showed following knowledge. First, as many NOB strains were newly isolated from a variety of environments, we got sufficient strains for studying microbial properties of them. Second, we explored new markers for phylogenetic classification for NOB. Third, we established a new phylogenetic classification with new markers, and we have applied it to "non-culture" analysis of NOB in natural environments.

广泛存在于整个环境中的亚硝酸盐氧化细菌（NOB）是负责硝化后期的细菌种类。但其中很少有菌株被作为纯培养物分离出来。本研究是为了探索遗传资源的有用性及其应用而进行的，得出了以下认识。首先，由于许多NOB菌株是从各种环境中新分离出来的，我们获得了足够的菌株来研究它们的微生物特性。其次，我们探索了 NOB 系统发育分类的新标记。第三，我们用新的标记建立了新的系统发育分类，并将其应用于自然环境中NOB的“非培养”分析。
