Two coccoid, non-motile bacteria were isolated from seawater in the north-western Pacific Ocean near Japan. The two strains, designated S1-36T and S1-72T, were Gram-negative, obligately aerobic, heterotrophic and catalase-negative. They were able to reduce nitrate to nitrogen. Both strains required NaCl for growth, with optimum growth in 2 % NaCl, and grew at 15–30 °C, with optimum growth at 20–25 °C. Genomic DNA G+C contents of strains S1-36T and S1-72T were 59.6 and 59.4 mol%, respectively. The predominant isoprenoid quinone was Q-8 and major cellular fatty acids were C16 : 1ω7c, C18 : 1ω7c and C17 : 1ω8c. Analyses of 16S rRNA gene sequences revealed that strains S1-36T and S1-72T were related to each other (96.1 % sequence similarity) and both strains showed 92.3–94.7 % sequence similarity with members of the genus Haliea . On the basis of phenotypic and phylogenetic features, strains S1-36T and S1-72T should be classified as representatives of two novel species in a new genus, Halioglobus gen. nov., within the class Gammaproteobacteria . The names proposed are Halioglobus japonicus sp. nov., the type species of the genus, with S1-36T ( = NBRC 107739T = KCTC 23429T) as type strain, and Halioglobus pacificus sp. nov., with S1-72T ( = NBRC 107742T = KCTC 23430T) as type strain.

Two Gram-stain-negative, catalase-positive, oxidase-negative, rod-shaped, non-flagellated, non-spore-forming and non-motile strains (YJ13CT and H41T) were isolated from a mariculture fishpond in PR China. Comparisons based on 16S rRNA gene sequences indicated that YJ13CT and H41T shared 16S rRNA gene sequences similarities between 92.6 and 99.2 % with species of the genus Algoriphagus . YJ13CT only shared 93.8 % 16S rRNA gene sequence similarity with H41T. The reconstructed phylogenetic and phylogenomic trees indicated that YJ13CT and H41T clustered closely with species of the genus Algoriphagus . The calculated pairwise orthologous average nucleotide identity with usearch (OrthoANIu) values between strains YJ13CT and H41T and other related strains were all less than 79.5 %. The OrthoANIu value between YJ13CT and H41T was only 69.9 %. MK-7 was the predominant respiratory quinone of YJ13CT and H41T and their major cellular fatty acids contained iso-C15 : 0, C16 : 1 ω7c and C17 : 1 ω9c. The polar lipids profiles of YJ13CT and H41T consisted of phosphatidylethanolamine and several kinds of unidentified lipids. Combining the above descriptions, strains YJ13CT and H41T represent two distinct novel species of the genus Algoriphagus , for which the names Algoriphagus pacificus sp. nov. (type strain YJ13CT=GDMCC 1.2178T=KCTC 82450T) and Algoriphagus oliviformis sp. nov. (type strain H41T=GDMCC 1.2179T=KCTC 82451T) are proposed.

Following phylogenetic analysis based on 16S rRNA gene sequences, together with DNA G+C contents and differential chemotaxonomic and physiological characteristics, a new genus with the name Aliiglaciecola gen. nov. is proposed to more appropriately accommodate two recognized species of the genera Glaciecola and Aestuariibacter . Accordingly, [Glaciecola] lipolytica and [ Aestuariibacter] litoralis should be reassigned to the novel genus as Aliiglaciecola lipolytica comb. nov. (type strain, E3T = JCM 15139T = CGMCC 1.7001T) and Aliiglaciecola litoralis comb. nov. (type strain, KMM 3894T = JCM 15896T = NRIC 0754T), respectively. Aliiglaciecola lipolytica is proposed as the type species of this new genus. Physiologically, the combined characteristics of positive reactions for nitrate reduction and growth at 4 °C and 36 °C distinguish the new genus from the genera Aestuariibacter and Glaciecola by one to three traits. Moreover, the new genus is also distinguished from the genus Glaciecola by the fatty acid profile and distinguished from the genus Aestuariibacter by the differences of major isoprenoid quinone (MK-7 vs Q-8) and DNA G+C content (40.8–43.0 mol% vs 48.0–54.0 mol%).
