Emended Description

A novel, Gram-staining-negative, non-flagellated, oval or short-rod-shaped, strictly aerobic and non-spore-forming marine bacterium, designated strain CC-AMW-CT, was isolated from coastal surface seawater in Kending County, Taiwan. Cells of strain CC-AMW-CT displayed unusual morphology and formed colourless or beige colonies on marine agar. The isolate shared pairwise 16S rRNA gene sequence similarities of 97.2 and 97.1 % with Shimia marina BCRC 80068T and Shimia isoporae BCRC 80085T, respectively, and established a discrete phyletic lineage closely associated with the members of the genus Shimia . DNA–DNA hybridization values indicated <18.2 % genomic relatedness with species of the genus Shimia . The polar lipid profile of strain CC-AMW-CT comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, two unidentified aminolipids, four unidentified lipids and an unidentified phospholipid. The predominant fatty acids were C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8; 75.5 %). The DNA G+C content was 61.2 mol%. The predominant respiratory quinone was ubiquinone Q-10 and the major polyamine was cadaverine. The chemotaxonomic evidence, including extraordinary amounts of C18 : 1ω7c and/or C18 : 1ω6c, major polar lipids, polyamine, quinone and DNA G+C contents of CC-AMW-CT, was in line with that of the members of the genus Shimia . Thus, strain CC-AMW-CT should be classified as a novel species of the genus Shimia , for which the name Shimia biformata sp. nov. is proposed. The type strain is CC-AMW-CT ( = JCM 18818T = BCRC 80548T). An emended description of the genus Shimia is also proposed.

A Gram-staining-negative, strictly aerobic, rod-shaped, non-flagellated, non-spore-forming and gliding marine bacterium designated strain CC-AMZ-301T was isolated from coastal surface seawater near Taichung harbour, Taiwan. Strain CC-AMZ-301T predominantly synthesized zeaxanthin and thus formed yellow colonies on marine agar. The novel strain showed high pairwise 16S rRNA gene sequence similarity to Kordia periserrulae IMCC1412T (95.0 %), K. algicida KCTC 8814PT (94.4 %) and K. antarctica IMCC3317T (94.2 %), and formed a phylogenetic lineage tightly associated with species of the genus Kordia . The polar lipid profile of strain CC-AMZ-301T consisted of three unidentified lipids, three unidentified aminolipids and one unidentified phospholipid. The major fatty acids (>5 % of total) were iso-C17 : 0 3-OH, iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0). The DNA G+C content was 36.4 mol%. Menaquinone 6 (MK-6) was the predominant respiratory quinone. The major polyamine was the triamine sym-homospermidine. Based on evidence from the present polyphasic study, strain CC-AMZ-301T is proposed to represent a novel species of the genus Kordia , for which the name Kordia aquimaris sp. nov. is proposed; the type strain is CC-AMZ-301T ( = JCM 18556T = BCRC 80464T). An emended description of the genus Kordia is also proposed.

Emended Description

A Gram-stain-negative, strictly aerobic, rod- or oval-shaped, motile, non-spore-forming bacterium, designated strain CC-AMHB-3T, was isolated from coastal surface seawater off Hualien, Taiwan. The novel strain showed high pairwise 16S rRNA gene sequence similarities to Ruegeria mobilis NBRC 101030T (96.5 %), Ruegeria scottomollicae LMG 24367T (96.4 %), Phaeobacter aquaemixtae SSK6-1T (96.2 %), Phaeobacter daeponensis TF-218T (96.2 %), Cribrihabitans marinus CZ-AM5T (96.1 %) and other species of the family Rhodobacteraceae (≤95.9 %). However, strain CC-AMHB-3T formed a distinct phyletic lineage associated with C. marinus CZ-AM5T during phylogenetic analyses. The polar lipid profile of strain CC-AMHB-3T included major amounts of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine; moderate amounts of phosphatidylethanolamine, an unidentified aminolipid, an unidentified phospholipid and an unidentified lipid; and trace amounts of an unidentified lipid and an unidentified phospholipid, which was qualitatively almost in line with that of C. marinus CZ-AM5T but remarkably distinct as compared with the type species of the genera Ruegeria ( Ruegeria atlantica JCM 21234T) and Phaeobacter ( Phaeobacter gallaeciensis JCM 21319T). In line with the fatty acid profile of C. marinus CZ-AM5T, the major (>5 % of total) fatty acids of strain CC-AMHB-3T were C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8), 11-methyl C18 : 1ω7c and C16 : 0. The DNA G+C content was 66.7 mol%. Ubiquinone-10 (Q-10) was the sole respiratory quinone. Thus, based on the results of the polyphasic study presented here, strain CC-AMHB-3T is considered to represent a novel species of the genus Cribrihabitans , for which the name Cribrihabitans neustonicus sp. nov. is proposed; the type strain is CC-AMHB-3T ( = JCM 19537T = BCRC 80695T). In addition, an emended description of the genus Cribrihabitans is also proposed.

Emended Description

Two Gram-staining-negative, yellow-pigmented, rod-shaped, strictly aerobic, non-flagellated and non-spore-forming amylolytic marine bacterial strains, designated CC-AMZ-30MT and CC-AMZ-30NT, were isolated from coastal surface seawater in Taiwan. Strain CC-AMZ-30MT shared pairwise 16S rRNA gene sequence similarities of 95.8, 95.0 and <94.0 % to Sphingomicrobium lutaoense CC-TBT-3T, Sphingomicrobium astaxanthinifaciens CC-AMO-30BT and other sphingomonads, respectively. Strain CC-AMZ-30NT shared 97.0, 96.7, 95.0 and <95.1 % similarities to strain CC-AMZ-30MT, Sphingomicrobium lutaoense CC-TBT-3T, Sphingomicrobium astaxanthinifaciens CC-AMO-30BT and other sphingomonads, respectively. The common polar lipids of the two strains include a signature glycolipid (GL2), diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and sphingoglycolipid in major amounts besides moderate-to-trace amounts of an unidentified aminolipid and several unidentified glycolipids. Both strains contained C18 : 1ω7c/C18 : 1ω6c, C16 : 1ω7c/C16 : 1ω6c, C16 : 0 and C18 : 1 2-OH as major (>5 % of the total) fatty acids. Strains CC-AMZ-30MT and CC-AMZ-30NT had DNA G+C contents of 64.2 and 65.2 mol%, respectively. The major polyamine was spermidine in strain CC-AMZ-30MT and triamine sym-homospermidine in strain CC-AMZ-30NT. Both strains contained ubiquinone Q-10 as the predominant respiratory quinone. Differential phylogenetic and chemotaxonomic evidence including the presence of characteristic GL2, C18 : 1 2-OH and several other phenotypic features supported the classification of strains CC-AMZ-30MT and CC-AMZ-30NT as two novel species of the genus Sphingomicrobium , for which we propose the names Sphingomicrobium marinum sp. nov. and Sphingomicrobium flavum sp. nov., respectively; corresponding type strains are Sphingomicrobium marinum CC-AMZ-30MT ( = JCM 18554T = BCRC 80466T) and Sphingomicrobium flavum CC-AMZ-30NT ( = JCM 18555T = BCRC 80467T). An emended description of the genus Sphingomicrobium is also proposed.
