A facultatively anaerobic sulfur-oxidizing bacterium, strain skT11 T , was isolated from anoxic lake water of a stratified freshwater lake. As electron donor for chemolithoautotrophic growth, strain skT11 T oxidized thiosulfate, tetrathionate, and elemental sulfur under nitrate-reducing conditions. Oxygen-dependent growth was observed under microoxic conditions, but not under fully oxygenated conditions. Growth was observed at a temperature range of 5–37 °C, with optimum growth at 28 °C. Strain skT11 T grew at a pH range of 5.1–7.5, with optimum growth at pH 6.5–6.9. Heterotrophic growth was not observed. Major components in the cellular fatty acid profile were C 16:1 and C 16:0 . The complete genome of strain skT11 T consisted of a circular chromosome with a size of 3.8 Mbp and G + C content of 60.2 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the strain skT11 T is related to sulfur-oxidizing bacteria of the genera Sulfuricella , Sulfurirhabdus, and Sulfuriferula , with sequence identities of 95.4% or lower. The analysis also indicated that these three genera should be excluded from the family Gallionellaceae , as members of another family. On the basis of its genomic and phenotypic properties, strain skT11 T (= DSM 110711 T = NBRC 114323 T ) is proposed as the type strain of a new species in a new genus, Sulfurimicrobium lacus gen. nov., sp. nov. In addition, emended descriptions of the families Gallionellaceae and Sulfuricellaceae are proposed to declare that Sulfuricellaceae is not a later synonym of Gallionellaceae .

含硫微生物菌属。十一月，sp。11 月，一种从湖水中分离出来的硫氧化剂，以及对硫菌科家族的审查，以表明它不是 Gallionellaceae 的后来的同义词

从分层淡水湖的缺氧湖水中分离出兼性厌氧硫氧化细菌 skT11 T 菌株。作为化学自养生长的电子供体，菌株 skT11 T 在硝酸盐还原条件下氧化硫代硫酸盐、连四硫酸盐和元素硫。在微氧条件下观察到氧依赖性生长，但在完全氧化条件下观察不到。在 5–37 °C 的温度范围内观察到生长，在 28 °C 下生长最佳。菌株 skT11 T 在 5.1-7.5 的 pH 范围内生长，最佳生长在 pH 6.5-6.9。未观察到异养生长。细胞脂肪酸谱中的主要成分是 C 16:1 和 C 16:0 。skT11 T 菌株的完整基因组由大小为 3.8 Mbp 和 G + C 含量为 60.2 mol% 的环状染色体组成。基于16S rRNA基因序列的系统发育分析表明，菌株skT11 T与Sulfuricella、Sulfurirhabdus和Sulfuriferula属的硫氧化细菌相关，序列同一性为95.4%或更低。分析还表明，这三个属应该被排除在 Gallionellaceae 科之外，作为另一个科的成员。根据其基因组和表型特性，菌株 skT11 T (= DSM 110711 T = NBRC 114323 T ) 被提议作为新属中的新物种 Sulfuurimicrobium lacus gen 的模式菌株。十一月，sp。十一月 此外，提议对 Gallionellaceae 和 Sulfuricellaceae 进行修正描述，以声明 Sulfuricellaceae 不是 Gallionellaceae 的后来同义词。
