Paracoccus angustae sp. nov., isolated from soil

A Gram-stain-negative, coccus-shaped, aerobic bacterium, strain E6T, was isolated from soil. 16S rRNA gene sequence analysis revealed a cluster containing strain E6T and Paracoccus sediminis CMB17T (the highest 16S rRNA gene similarity of 97.2 %). The other strains investigated showed 16S rRNA gene sequence similarities of less than 97 % to strain E6T. The DNA–DNA relatedness between strain E6T and P. sediminis DSM 26170T was 59.2 %. Strain E6T also shows some differences compared with other Paracoccus strains such as motility and inability to utilize lactate and propionate as sole carbon sources. The major fatty acids of strain E6T were C18 : 1ω7c and C18 : 0 and ubiquinone-10 was the only respiratory quinone. Strain E6T had diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an unknown aminolipid and an unknown glycolipid as major polar lipids. The genomic DNA G+C content was 68.1 mol%. On the basis of phenotypic and genotypic characteristics, strain E6T is concluded to represent a novel species of the genus Paracoccus, for which the name Paracoccus angustae sp. nov. is proposed. The type strain is E6T ( = KCTC 42473T = CCTCC AB 2015056T).
