Anammox bacteria exhibit remarkable and characteristic metabolic features that enable them to oxidize ammonium under anoxic conditions. Their ultrastructure is complex, with three compartments, comprising paryphoplasm, the riboplasm and the anammoxosome. The latter is surrounded by ladderane lipids, creating a lipid-surrounded organelle within the riboplasm. In this edition of Molecular Microbiology, van Niftrik and co-workers present detailed ultrastructural investigations that, together with the analysis of the product of a predicted gene and its localization in ultrathin sections, provide the first hints at the way in which these cells divide.
厌氧氨氧化细菌具有显著且独特的代谢特征，使其能够在缺氧条件下氧化铵。它们的超微结构复杂，有三个区室，包括周质、核糖质和厌氧氨氧化体。后者被梯烷脂质包围，在核糖质内形成一个被脂质包围的细胞器。在本期《分子微生物学》中，范·尼夫特里克及其同事进行了详细的超微结构研究，这些研究连同对一个预测基因产物的分析及其在超薄切片中的定位，首次揭示了这些细胞的分裂方式。
