A novel alphaproteobacterium, designated as KMU-115^T, was isolated from seawater collected on the coast of Chuam Beach, Republic of Korea, and subjected to a polyphasic characterization. The cells were pale apricot-colored, strictly aerobic, Gram-staining-negative, rod-shaped, non-motile and chemoorganoheterotrophic. The novel isolate grew at NaCl concentrations of 0–7%, pH 6.0–9.5 and 10–45°C. A phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain KMU-115^T belongs to the family ‘Rhodobacteraceae’, and that it had the greatest sequence similarity (96.8%) with ‘Roseibacterium beibuensis’ JLT1202r^T. The major respiratory quinone system of the novel isolate was ubiquinone-10 (Q-10) and the main (>10%) cellular fatty acid was C18:1 ω7c. The assembled draft genome size of strain KMU-115^T was 3.71 Mbp. The genomic DNA G + C content was 70.8 mol%. Strain KMU-115^T had phosphatidylglycerol, four unidentified aminolipids, an unidentified aminophospholipid and seven unidentified lipids as polar lipids. From the distinct polyphasic taxonomic characteristics, the strain is considered to represent a novel species of the genus Roseibacterium for which the name Roseibacterium persicicum sp. nov. is proposed. The type strain of R. persicicum sp. nov. is KMU-115^T (= KCCM 90339^T = NBRC 114190^T). An emended description of the genus Roseibacterium is also provided.

玫瑰迷迭香属细菌的表征。十一月十一日，并修订了迷迭香属的描述。

从大韩民国Chuam Beach海岸收集的海水中分离出一种新型α变形杆菌，命名为KMU-115 ^T，并进行了多相表征。细胞是浅杏色的，严格需氧的，革兰氏染色阴性的，棒状的，不运动的和化学异养的。新分离株在NaCl浓度为0–7％，pH 6.0–9.5和10–45°C时生长。根据16S rRNA基因序列的系统发育分析表明，菌株KMU-115 ^T属于“红杆菌科”，与“ Beibuensis迷迭香” JLT1202r ^T具有最大的序列相似性（96.8％）。。新颖的分离物的主要呼吸醌系统是泛醌-10（Q-10）和主（> 10％）细胞脂肪酸是C18：1 ω 7 Ç。菌株KMU-115 ^T的组装的基因组草图大小为3.71 Mbp。基因组DNA G + C含量为70.8mol％。菌株KMU-115 ^T具有磷脂酰甘油，四个未鉴定的氨基脂质，一个未鉴定的氨基磷脂和七个未鉴定的脂质作为极性脂质。从不同的多相分类特征，该菌株被认为是代表属的一个新种Roseibacterium的量，名称Roseibacterium persicicum藻。十一月 被提议。百日草（R. persicicum sp。）十一月 是KMU-115^T（= KCCM 90339 ^T  = NBRC 114190 ^T）。还提供了迷迭香属的改良描述。
