Abstract

A Gram-stain-negative, aerobic, non-motile, rod-shaped, agarolytic and carrageenolytic bacterial strain, designated UJ94 <superscript>T</superscript> , was isolated from seawater of Uljin in the Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain UJ94 <superscript>T</superscript> shared sequence similarities of 98.4, 96.1 and 95.4 % with Tamlana agarivorans JW-26 <superscript>T</superscript> , Tamlana sedimentorum KMM 9545 <superscript>T</superscript> and Tamlana crocina HST1-43 <superscript>T</superscript> , respectively. Growth of strain UJ94 <superscript>T</superscript> was observed at 4-37 °C and pH 6.5-8.0 in the presence of 2-9 % (w/v) NaCl. The major fatty acids of strain UJ94 <superscript>T</superscript> were iso-C15 : 0, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) and iso-C17 : 0 3-OH; MK-6 was the predominant menaquinone. Phosphatidylethanolamine, two unidentified aminolipids and five unidentified lipids were detected as major polar lipids. The whole circular genome comprised 4 116 543 bp and had a G+C content of 35.2 mol%. The ranges of average nucleotide identity and in silico DNA-DNA hybridization estimated by genome-to-genome distance were 90.6-74.2 % and 47.6-14.6 %, respectively, with the type strains of T. agarivorans and T. sedimentorum. The present polyphasic study, including phylogenetic, chemotaxonomic, biochemical and genomic data, suggested that strain UJ94 <superscript>T</superscript> represents a novel species of the genus Tamlana, for which the name Tamlana carrageenivorans sp. nov. is proposed. The type strain is UJ94 <superscript>T</superscript> (=KCTC 62451 <superscript>T</superscript> =NBRC 113234 <superscript>T</superscript> ).
