Cumulibacter soli sp. nov., isolated from farmland soil.

A Gram-stain-positive, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterium, designated as strain G-1 ^T , was isolated from farmland soil sampled in in Fuyang, Anhui Province, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain G-1 ^T was closely related to Cumulibacter manganitolerans 2-36 ^T (97.7 % similarity). Strain G-1 ^T contained iso-C _16 : 0 , C _17 : 1 ω6 c , iso-C _15 : 0 and iso-C _14 : 0 as the predominant fatty acids. The polar lipids of strain G-1 ^T were diphosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid, an unidentified lipid and two unidentified glycolipids. The predominant respiratory quinone of strain G-1 ^T was MK-9(H ₄ ). The cell wall contained meso -diaminopimelic acid as the diagnostic diamino acid. The G+C content of the genomic DNA based on genome calculations was 64.2 mol%. Average nucleotide identity and the digital DNA-DNA hybridization values for the draft genomes between strain G-1 ^T and strain 2-36 ^T were 75.7 and 20.2 %, respectively. On the basis of phenotypic and phylogenetic data, strain G-1 ^T is considered to represent a novel species of the genus Cumulibacter , for which the name Cumulibacter soli sp. nov. is proposed. The type strain is G-1 ^T (=CCTCC AB2019021 ^T =KCTC 49258 ^T ).
