Two bacterial strains, designated KV-962(T) and KV-963, were isolated from soil collected from a field in Japan. Cells of both strains were Gram-staining-positive, non-spore-forming, short rod-shaped and motile. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these strains were related to Conexibacter woesei DSM 14684(T), with a similarity value of 98.6 %. These strains possessed MK-7 (H(4)) as the sole menaquinone and contained C(18 : 1)ω9c, C(17 : 1)ω6c and iso-C(16 : 0) as the major fatty acids. On the basis of genotypic and phenotypic characteristics, strain KV-962(T) and KV-963 were indicated as a novel species of the genus Conexibacter, for which the name Conexibacter arvalis sp. nov. is proposed. The type strain is KV-962(T) ( = DSM 23288(T) = NBRC 106558(T)).
两株细菌菌株，命名为 KV-962(T) 和 KV-963，从日本田间采集的土壤中分离得到。两株菌的细胞均为革兰氏阳性、非孢子形成、短杆状和运动的。基于 16S rRNA 基因序列的系统发育分析表明，这些菌株与 Conexibacter woesei DSM 14684(T) 密切相关，相似度值为 98.6%。这些菌株均含有 MK-7 (H(4)) 作为唯一的menaquinone，且含有 C(18 : 1)ω9c、C(17 : 1)ω6c 和 iso-C(16 : 0) 作为主要脂肪酸。根据基因型和表型特征，菌株 KV-962(T) 和 KV-963 被鉴定为 Conexibacter 属的一个新种，命名为 Conexibacter arvalis sp. nov.。模式菌株为 KV-962(T)（=DSM 23288(T)=NBRC 106558(T)）。
