Abstract
A Gram-stain negative, non-spore-forming, non-motile, strictly aerobic bacterial strain, designated CAU 1296T, was isolated from an aquafarm waste water sludge and its taxonomic position was investigated using a polyphasic approach. Cells of strain CAU 1296T grew optimally at 30 °C, at pH 7.5 and in the presence of 4 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU 1296T formed a distinct lineage within the genus Eudoraea and exhibited similarity to Eudoraea adriatica AS06/20aT (95.4 % similarity). The major cellular fatty acids of the isolate were iso-C15:0, iso-C15:1 G, and summed feature 3 (C16:1 ω6c and C16:1 ω7c). The polar lipid pattern of strain CAU 1296T consisted of phosphatidylethanolamine, and unidentified lipids including a phosphoglycolipid, phospholipid, glycolipid, aminophospholipid, two aminolipids, and six further unidentified lipids. The strain contained menaquinone-6 (MK-6) as the major isoprenoid quinone. The G+C content of the genomic DNA was 38.7 mol%. On the basis of phenotypic, chemotaxonomic, and phylogenetic data, strain CAU 1296T should be classified as a novel species in the genus Eudoraea, for which the name Eudoraea chungangensis sp. nov. is proposed. The type strain is CAU 1296T (=KCTC 42048T, =CCUG 66239T, =CECT 8744T).
