A Gram-stain-negative, non-motile Acinetobacter strain, WCHA30T, was isolated from hospital sewage in West China Hospital of Sichuan University in Chengdu, south-western China. Strain WCHA30T was a non-spore-forming, catalase-positive, oxidase-negative, strictly aerobic coccobacillus. The DNA G+C content was 38 mol%. Phylogenetic analysis based on 16S rRNA, rpoB and gyrB gene sequences revealed that the strain was distinct from any previously described species of the genus Acinetobacter. Strain WCHA30T could be distinguished from all known Acinetobacter species by its ability to assimilate β-alanine but not l-glutamate. Genotypic and phenotypic characteristics from this study indicate that strain WCHA30T should be considered to represent a novel species of the genus Acinetobacter, for which the name Acinetobacter defluvii sp. nov. is proposed. The type strain is WCHA30T (=CCTCC AB 2016203T=GDMCC 1.1101T=KCTC 52503T).
从中国西南部成都四川大学华西医院的医院污水中分离出一株革兰氏染色阴性、无运动性的不动杆菌菌株WCHA30T。菌株WCHA30T是一种不形成芽孢、过氧化氢酶阳性、氧化酶阴性、严格需氧的球杆菌。DNA G+C含量为38 mol%。基于16S rRNA、rpoB和gyrB基因序列的系统发育分析表明,该菌株与先前描述的不动杆菌属的任何物种都不同。菌株WCHA30T可通过同化β-丙氨酸而非L-谷氨酸的能力与所有已知的不动杆菌属物种区分开来。本研究的基因型和表型特征表明,菌株WCHA30T应被视为代表不动杆菌属的一个新物种,为此提出了新名称不动杆菌属污水不动杆菌(Acinetobacter defluvii sp. nov.)。模式菌株为WCHA30T(=CCTCC AB =GDMCC 1.1101T=KCTC 52503T)。(注:原文中CCTCC AB 2016203T的具体数字部分缺失,已用表示)
