Sphingorhabdus lutea sp. nov., isolated from sea water

Sphingorhabdus lacus sp. nov. and Sphingorhabdus profundilacus sp. nov., isolated from freshwater environments

“…Strains IMCC1753 T and IMCC26285 T contained PE, PME, PC, PG, DPG and SGL as major polar lipids (Fig. S3), similar to major polar lipids of Sphingorhabdus [9,12,[15][16][17]. The major polyamine and polar lipids of both strains were highly similar except for the presence of an unidentified glycolipid and an unidentified lipid in strain IMCC26285 T .…”

“…The genus Sphingorhabdus of the family Sphingomonadaceae was first proposed by Jogler et al [9] with the description of Sphingorhabdus planktonica and the reclassification of three Sphingopyxis species. Recently, four species of the genus Sphingorhabdus have been transferred to the novel genus Parasphingorhabdus [10], and therefore the genus Sphingorhabdus currently comprises nine species with validly published names which have been isolated from diverse environments such as freshwater [11,12], seashore sediment [13], arctic soil [14], seawater [15], wetland [16] and contaminated Petri dish [17]. The genus is characterized by Gram-stain-negative and aerobic bacteria that contain ubiquinone-10 (Q-10) as the major respiratory quinone, spermidine as the major polyamine and phosphatidylethanolamine (PE), phosphatidylmethylamine (PME), phosphatidylcholine (PC), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG) and SGL as the major polar lipids [9,12,14].…”

According to the EzBiocloud database containing quality controlled bacterial genomes [18], the whole genomes of Sphingorhabdus species range from 2.18 to 4.19 Mbp in size with 46.1-64.5 % [14,15] G+C content.…”

Transfer of Sphingorhabdus marina, Sphingorhabdus litoris, Sphingorhabdus flavimaris and Sphingorhabdus pacifica corrig. into the novel genus Parasphingorhabdus gen. nov. and Sphingopyxis baekryungensis into the novel genus Novosphingopyxis gen. nov. within the family Sphingomonadaceae

“…Meanwhile, the phenotypic and chemotaxonomic differences between Sphingopyxis baekryungensis KCTC 12231 T and closely related taxa were clearly shown in nitrate reduction, hydrolysis of aesculin, the major polyamine, the major fatty acid and 2-hydroxy fatty acid profiles and the genomic DNA G+C contents ( *All the data were from this study under the same conditions unless indicated otherwise. †Data from [15,[32][33][34][35][38][39][40][41][42]. a, Data from the whole genome sequences (ATUR00000000); b, data from the whole genome sequences (QRDP00000000); c, data from [43].…”

“…For phenotypic and chemotaxonomic characterizations, Clade I and Clade II of the genus Sphingorhabdus almost showed the same reactions in nitrate reduction, oxidase, hydrolyses of gelatin and starch and the major polyamine and similar genomic DNA G+C content range with exception of the species Sphingorhabdus lutea (46.1 mol%) [32]. However, they could be clearly distinguished from each other in activities of urease, catalase, the major fatty acids and 2-hydroxy fatty acids (Table S3).…”
