Strain S3-2, isolated from sediment of a frozen freshwater pond, shares 99% 16S rRNA gene sequence identity with strains of the genus . Strain S3-2 is a facultative anaerobe that lacks the ability to produce violacein but shows antibiotic resistance, psychrotolerance, incomplete denitrification, and fermentation. The draft genome of strain S3-2 has a size of ~5.8 Mbp and contains 5,297 genes, including 115 RNA genes. Based on the phenotypic properties of the strain, the low DNA-DNA hybridization (DDH) values with related genomes (<35%), and the low whole genome-based average nucleotide identity (ANI) (<86%) with other strains within the genus we propose that strain S3-2 is the type strain (= DSM 102223 = LMG 29653) of a new species within this genus. We propose the name sp. nov. to emphasize the capability of the strain to grow at low temperatures.
从一个冰冻淡水池塘的沉积物中分离出的菌株S3-2,其16S rRNA基因序列与该属的菌株有99%的同一性。菌株S3-2是一种兼性厌氧菌,缺乏产生紫菌素的能力,但具有抗生素抗性、耐冷性、不完全反硝化作用和发酵能力。菌株S3-2的基因组草图大小约为5.8 Mbp,包含5297个基因,其中包括115个RNA基因。基于该菌株的表型特性、与相关基因组的低DNA-DNA杂交(DDH)值(<35%)以及与该属内其他菌株的低全基因组平均核苷酸同一性(ANI)(<86%),我们提出菌株S3-2是该属内一个新物种的模式菌株(=DSM 102223 = LMG 29653)。我们提议将其命名为 sp. nov.,以强调该菌株在低温下生长的能力。
