Abstract |
A novel facultatively anaerobic, Gram-stain-negative bacterium, designated strain HT7-2(T), was isolated from Ulva prolifera collected from the intertidal zone of Qingdao sea area, China, during its bloom. Cells were rod-shaped (1.9-3.5×0.4-0.6 µm), non-sporulating and motile by gliding. Strain HT7-2(T) 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 HT7-2(T) belonged to the genus Maribacter with sequence similarity values of 94.5-96.6 %, and was most closely related to Maribacter aestuarii GY20(T) (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 HT7-2(T) consisted of one phosphatidylethanolamine, four unidentified lipids and one unidentified aminolipid. On the basis of the phenotypic, phylogenetic and chemotaxonomic characteristics, strain HT7-2(T) ( =CGMCC 1.12207(T) =JCM 18466(T)) 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.
