RESUMEN
A pink-pigmented bacterium (strain JC162T = KCTC 32190T) was isolated from a beach sand sample. Cells were Gram-stain-negative, coccoid, non-motile, and strictly aerobic. EzBioCloud BLAST search of 16S rRNA gene sequence showed that strain KCTC 32190T had the highest sequence identity to the members of the genus Neoroseomonas and was closely related to N. oryzicola YC6724T (99.8%), N. sediminicola FW-3T (98.5%), N. soli 5N26T (98.2%), and other members of the genus Neoroseomonas (< 97.9%) in the family Acetobacteriaceae within the class of Alphaproteobacteria. Chemo-organoheterotrophy was the only growth mode and growth was possible on a wide range of organic substrates. Strain KCTC 32190T was positive for catalase and oxidase. Fatty acid composition of strain KCTC 32190T includes (in decreasing %) C18:1ω7c, cyclo-C19:0ω8c, C18:02-OH, C16:0, C18:03-OH, C16:1ω7c/C16:1ω6c, C16:02-OH and C16:1ω5c. Polar lipids comprised of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified amino lipid, and three unidentified lipids. The genomic DNA G+C content of the strain KCTC 32190T was 70.9 mol%. Strain KCTC 32190T has a low ANI value of < 92.7% and genome reassociation (based on digital DNA-DNA hybridization) value of < 48.8% with the nearest type strains. The genome relatedness is supported by other polyphasic taxonomic data to propose strain KCTC 32190T as a new species in the genus Neoroseomonas with the name Neoroseomonas marina sp. nov. The type strain is strain JC162T (KCTC 32190T = CGMCC1.12364T).
