Pseudomonas stutzeri is a nonfluorescent denitrifying bacterium widely distributed in the environment, and it has also been isolated as an opportunistic pathogen from humans. Over the past 15 years, much progress has been made in elucidating the taxonomy of this diverse taxonomical group, demonstrating the clonality of its populations. The species has received much attention because of its particular metabolic properties: it has been proposed as a model organism for denitrification studies; many strains have natural transformation properties, making it relevant for study of the transfer of genes in the environment; several strains are able to fix dinitrogen; and others participate in the degradation of pollutants or interact with toxic metals. This review considers the history of the discovery, nomenclatural changes, and early studies, together with the relevant biological and ecological properties, of P. stutzeri.
斯氏假单胞菌是一种非荧光反硝化细菌,广泛分布于环境中,也从人类身上分离出作为一种机会致病菌。在过去15年里,在阐明这个多样化分类群的分类学方面取得了很大进展,证明了其种群的克隆性。该物种因其特殊的代谢特性而备受关注:它被提议作为反硝化研究的模式生物;许多菌株具有自然转化特性,这使其与环境中基因转移的研究相关;一些菌株能够固定氮气;其他菌株则参与污染物的降解或与有毒金属相互作用。这篇综述考虑了斯氏假单胞菌的发现历史、命名变化、早期研究以及相关的生物学和生态学特性。
