A Gram-stain-negative, rod-shaped bacterial strain, JC4, was isolated from a freshwater sample and determined the taxonomic position. Initial identification based on 16S rRNA gene sequences revealed that strain JC4 is affiliated to the genus with a sequence similarity of 97.97% to WPCB133. The average nucleotide identity and digital DNA-DNA hybridization values between strain JC4 and species were estimated below 80.92% and 23.9%, respectively. Strain JC4 contained summed feature 3 (C 7 and/or C 6) and iso-C as predominant cellular fatty acids. The dominant polar lipids were identified as phosphatidylethanolamine, one unidentified aminophospholipid, one unidentified phospholipid, and two unidentified lipids. The respiratory quinone was MK-7. The genomic DNA G+C content of strain JC4 was determined to be 42.44%. The above polyphasic evidences support that strain JC4 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JC4 (= KCTC 92230 = LMG 32715).
一株革兰氏阴性、杆状的细菌 JC4 菌株，从淡水样本中分离出来，并确定了其分类地位。基于 16S rRNA 基因序列的初步鉴定表明，菌株 JC4 属于 属，与 WPCB133 的序列相似性为 97.97%。菌株 JC4 与 种之间的平均核苷酸同一性和数字 DNA-DNA 杂交值分别估计为低于 80.92%和 23.9%。菌株 JC4 含有主要的细胞脂肪酸为(summed feature 3，C7 和/或 C6)和 iso-C。主要的极性脂类被鉴定为磷脂酰乙醇胺、一种未鉴定的氨基磷脂、一种未鉴定的磷脂和两种未鉴定的脂类。呼吸醌为 MK-7。菌株 JC4 的基因组 DNA G+C 含量为 42.44%。上述多相证据支持菌株 JC4 代表了 属的一个新种，因此提议使用新种名 sp. nov.。模式菌株为 JC4(=KCTC 92230=LMG 32715)。
