A novel aerobic, yellow-pigmented, Gram-stain-negative, rod-shaped bacterial strain, CUG00004T, was isolated from a soil sample. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CUG00004T was a member of the genus Flavobacterium and showed high sequence similarity with Flavobacterium soli DSM 19725T (96.9 %) and Flavobacterium glaciei CGMCC 0499T (95.6 %). The level of DNA-DNA relatedness between strain CUG00004T and F. soli DSM 19725T and F. glaciei CGMCC 1.5380T was 42.5 and 43.4 %, respectively. Strain CUG00004T was moderately alkaliphilic and grew optimally at pH 8.0, at 28 °C and in the presence of 0-1 % (w/v) NaCl. This organism contained menaquinone-6 (MK-6) as the only isoprenoid quinone and iso-C15 : 0, iso-C17 : 0 3-OH, anteiso-C15 : 0 and summed feature 9 (comprising iso-C17 : 1ω9c and/or C16 : 0 10-methyl) as the major fatty acids. The DNA G+C content of strain CUG00004T was 36.3 mol%. On the basis of phylogenetic, physiological and chemotaxonomic analyses, strain CUG00004T represents a novel species, for which the name Flavobacterium terriphilum sp. nov. is proposed. The type strain is CUG00004T (=CCTCC AB 2014151T=KCTC 42876T).
从一份土壤样品中分离出一株新型需氧、产黄色色素、革兰氏染色阴性、杆状的细菌菌株CUG00004T。基于16S rRNA基因序列的系统发育分析表明,菌株CUG00004T是黄杆菌属的成员,与土壤黄杆菌DSM 19725T(96.9%)和冰川黄杆菌CGMCC 0499T(95.6%)显示出高序列相似性。菌株CUG00004T与土壤黄杆菌DSM 19725T以及冰川黄杆菌CGMCC 1.5380T之间的DNA-DNA相关性水平分别为42.5%和43.4%。菌株CUG00004T为中度嗜碱菌,在pH 8.0、28℃以及0-1%(w/v)NaCl存在的条件下生长最佳。该菌株含有甲基萘醌-6(MK-6)作为唯一的类异戊二烯醌,以及异C15 : 0、异C17 : 0 3-OH、anteiso-C15 : 0和总和特征9(包括异C17 : 1ω9c和/或C16 : 0 10-甲基)作为主要脂肪酸。菌株CUG00004T的DNA G+C含量为36.3 mol%。基于系统发育、生理和化学分类分析,菌株CUG00004T代表一个新物种,为此提出新名为嗜土黄杆菌(Flavobacterium terriphilum sp. nov.)。模式菌株为CUG00004T(=CCTCC AB 2014151T=KCTC 42876T)。
