从盐土中分离到一株新的嗜中、嗜酸性革兰氏阳性细菌，命名为TC-34（T）。菌株TC-34（T）在17-40 ℃和pH 2.0-6.0下有氧生长，最佳在28 ℃和pH 3.0下生长。16 S rRNA基因序列分析表明，菌株TC-34（T）与苹果脂环酸芽孢杆菌（Alicyclobacilluspomorum）的同源性最高（94.8%），属于脂环酸芽孢杆菌属（Alicyclobacilluspomorum）。菌株TC-34（T）显示出一系列表型特征，这些特征将其与公认的脂环酸芽孢杆菌物种区分开，包括生长温度、碳源同化和从一系列化合物产生酸。菌株TC-34（T）具有氧化亚铁的能力，其生长与培养基中Fe ~（2+）的氧化有关。未检测到ω-脂环族脂肪酸。根据这些结果，可以得出结论，菌株TC-34（T）代表脂环酸芽孢杆菌属的一个新种，建议将其命名为氧化亚铁脂环酸芽孢杆菌（模式菌株TC-34（T）= JCM 15090（T）= CGMCC 1.6357（T））。
A novel mesophilic and acidophilic Gram-positive bacterium, designated strain TC-34(T), was isolated from solfataric soil. Strain TC-34(T) grew aerobically at 17-40 degrees C and pH 2.0-6.0, and optimally at 28 degrees C and pH 3.0. Analysis based on 16S rRNA gene sequences showed that strain TC-34(T) was phylogenetically related to members of the genus Alicyclobacillus, with the highest similarity (94.8%) to Alicyclobacillus pomorum. Strain TC-34(T) showed a range of phenotypic characteristics that differentiated it from recognized Alicyclobacillus species, including growth temperature, assimilation of carbon sources and production of acids from a range of compounds. Strain TC-34(T) was able to oxidize ferrous iron and its growth was correlated with the oxidation of Fe2+ in culture medium. omega-Alicyclic fatty acids were not detected. On the basis of these results, it was concluded that strain TC-34(T) represents a novel species of the genus Alicyclobacillus, for which the name Alicyclobacillus ferrooxydans (type strain TC-34(T) = JCM 15090(T) = CGMCC 1.6357(T)) is proposed.
