Abstract
The bacterial strain AP-MA-4T isolated from the marine dinoflagellate Alexandrium pacificum (KCTC AG60911), was subjected to a taxonomic analysis. Cells of strain AP-MA-4T were Gram-stain-negative, aerobic, rod-shaped, optimum growth at 20 °C, pH 7.0, in the presence of 5% (w/v) NaCl. Strain AP-MA-4T shared the highest 16S rRNA gene sequence similarity to Pseudosulfitobacter pseudonitzschiae DSM 26824T (98.5%), followed by Ascidiaceihabitans donghaensis RSS1-M3T (96.3%), Pseudoseohaeicola caenipelagi BS-W13T (95.7%), and Sulfitobacter pontiacus CHLG 10T (95.3%). Based on 16S rRNA phylogeny, strain AP-MA-4T is phylogenetically closely related to Pseudosulfitobacter pseudonitzschiae (type species of Pseudosulfitobacter) and could be distinguished from the type species based on their phenotypic properties. The genome length of strain AP-MA-4T was 3.48 Mbp with a 62.9% G + C content. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between strain AP-MA-4 T and its closely related type strains were 72.2–83.3 and 18.2–27.6%, respectively. Summed feature 8 (C18:1ω7c and/or C18:1ω6c) was identified the major fatty acids (> 10%). Phosphatidylglycerol (PG), phosphatidylethanolamine (PE), and phospholipid (PL) were demonstrated as the major polar lipids. The major respiratory quinone is ubiquinone-10 (Q-10). Based on genotypic and phenotypic features, strain AP-MA-4T (= KCTC 92289T = GDMCC 1.3585T) represents a new Pseudosulfitobacter species, in which the name Pseudosulfitobacter koreense sp. nov. is proposed.
