在世界各地的自然和人造生态系统中都可以检测到介导铵厌氧氧化 (anammox) 的细菌，它们对海洋中无机氮的损失造成高达 50% 的影响。两种不同的厌氧氨氧化物种很少生活在同一个栖息地，这表明每个物种都有一个明确但未知的生态位。在这里，我们描述了一种具有明确利基的新型厌氧铵氧化细菌：丙酸盐和铵的共氧化。新的厌氧氨氧化物种在实验室规模的生物反应器中在铵和丙酸盐的存在下得到富集。有趣的是，在存在铵、亚硝酸盐和硝酸盐的情况下，这种特殊的厌氧氨氧化物种可以在丙酸盐氧化方面击败其他厌氧氨氧化细菌和异养反硝化菌。我们暂时将新物种命名为“Anammoxoglobus propionicus”。 (c) 2006 年爱思唯尔有限公司。版权所有。
The bacteria that mediate the anaerobic oxidation of ammonium (anammox) are detected worldwide in natural and man-made ecosystems, and contribute up to 50% to the loss of inorganic nitrogen in the oceans. Two different anammox species rarely live in a single habitat, suggesting that each species has a defined but yet unknown niche. Here we describe a new anaerobic ammonium oxidizing bacterium with a defined niche: the co-oxidation of propionate and ammonium. The new anammox species was enriched in a laboratory scale bioreactor in the presence of ammonium and propionate. Interestingly, this particular anammox species could out-compete other anammox bacteria and heterotrophic denitrifiers for the oxidation of propionate in the presence of ammonium, nitrite and nitrate. We provisionally named the new species Candidatus "Anammoxoglobus propionicus". (c) 2006 Elsevier GmbH. All rights reserved.
