ABSTRACT
A Gram-stain-negative, short-rod-shaped and pink-pigmented bacterial strain (HB172049T) was isolated from mangrove sediment. Cells grew at 10-45 °C (optimum, 30 °C), pH 6.0-9.0 (optimum, pH 7.0) and with 0.5-9.0â% (w/v) NaCl (optimum, 2-5â%). Analysis of the 16S rRNA gene sequence revealed that the isolate had highest sequence similarities to Pontibacter mucosus DSM 100162T (96.5â%) and Pontibacter korlensis X14-1T (96.5â%). The values of average nucleotide identity, average amino acid identity and digital DNA-DNA hybridization between the isolate and its close neighbours were, respectively, less than 80.1, 81.7 and 23.2â%. Chemotaxonomic analysis indicated that the sole respiratory quinone was MK-7 and the predominant cellular fatty acids were summed feature 4 and iso-C15ââ0 (42.2 and 24.6â%, respectively). The major polar lipids consisted of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, one unidentified glycolipid, one unidentified phospholipid, one unidentified aminophospholipid and two unidentified polar lipids. The genomic DNA G+C content was 52.6 mol%. Based on polyphasic taxonomic characterization, it is proposed that strain HB172049T belongs to the genus Pontibacter and represents a novel species, for which the name Pontibacter mangrovi sp. nov. is proposed. The type strain is HB172049T (=CGMCC 1.16729T=JCM 33333T).
