abstract= A Gram-stain-negative, facultatively anaerobic, orange-pigmented bacterium, designated HQYD1T, was isolated from a sea squirt (Styelaclava) and characterized using a polyphasic approach. Morphologically, strain HQYD1T exhibited rods with gliding motility. This novel isolate grew optimally at 28 °C in the presence of 2–3 % (w/v) NaCl. The 16S rRNA gene sequence was most similar to [ Saccharicrinis ] marinus Y11T (96.3 %), followed by Saccharicinis fermentans DSM 9555T (93.8 %). The dominant fatty acids of strain HQYD1T were identified as C16 : 0, C18 : 0 and iso-C15 : 0. Major polar lipids included an unidentified lipid and a phospholipid. The major respiratory quinone was found to be MK-7, and the genomic DNA G+C content was determined to be 35.1 mol%. Based on evidence from this taxonomic study, a novel genus, Labilibacter gen. nov., is proposed in the family Marinilabiliaceae with type species Labilibacter aurantiacus sp. nov. The type strain of the type species is HQYD1T (=MCCC 1K02304T=KCTC 42583T). As [ Saccharicrinis ] marinus Y11T clustered phylogenetically with strain HQYD1T, we also propose [ Saccharicrinis ] marinus Y11T be reclassified as Labilibacter marinus comb. nov. (type strain Y11T=CICC 10837T=KCTC 42400T).,
