Cells were rod-shaped (1.9–3.5×0.4–0.6 µm), non-sporulating and motile by gliding. Strain HT7-2T was able to grow at 4–50 °C (optimum 40–42 °C), pH 5.5–8.5 (optimum pH 7.0), 0–8 % (w/v) NaCl (optimum 2–3 %) and 0.5–10 % (w/v) sea salts (optimum 2.5 %). The genomic DNA G+C content was 38.8 mol%. The phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HT7-2T belonged to the genus Maribacter with sequence similarity values of 94.5–96.6 %, and was most closely related to Maribacter aestuarii GY20T (96.6 %). Chemotaxonomic analysis showed that the main isoprenoid quinone was MK-6 and the major fatty acids were iso-C15 : 0 and unknown equivalent chain-length 13.565. The polar lipids of strain HT7-2T consisted of one phosphatidylethanolamine, four unidentified lipids and one unidentified aminolipid. On the basis of the phenotypic, phylogenetic and chemotaxonomic characteristics, strain HT7-2T ( = CGMCC 1.12207T = JCM 18466T) is concluded to represent a novel species of the genus Maribacter , for which the name Maribacter thermophilus sp. nov. is proposed. An emended description of the genus Maribacter is also proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.064774-0
