A novel bacterium, strain BrT, was isolated from gamma-irradiated soils of the Britannia drift, Lake Wellman Region, Antarctica. This isolate was rod-shaped, endospore forming, Gram-stain-variable, catalase-positive, oxidase-negative and strictly aerobic. Cells possessed a monotrichous flagellum. Optimal growth was observed at 18 °C, pH 7.0 in PYGV or R2A broth. The major cellular fatty acid was anteiso-C15 : 0 (63.4 %). Primary identified lipids included phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. Total phospholipid was 60 % (w/w) of the total lipid extract. MK-7 was the dominant isoprenoid quinone. The genomic DNA G+C content was 55.6 mol%. Based on 16S rRNA gene sequence similarity, strain BrT clusters within the genus Paenibacillus with similarity values ranging from 93.9 to 95.1 %. Phylogenetic analyses by maximum-likelihood, maximum-parsimony and neighbour-joining methods revealed that strain BrT clusters with Paenibacillus daejeonensis (AF290916), Paenibacillus tarimensis (EF125184) and Paenibacillus pinihumi (GQ423057), albeit with weak bootstrap support. On the basis of phenotypic, chemotaxonomic and phylogenetic characteristics, we propose that strain BrT represents a novel species, Paenibacillus darwinianus sp. nov. The type strain is BrT ( = DSM 27245T = ICMP 19912T).

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.

A novel Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic strain with gliding motility, designated SW024T, was isolated from surface seawater of the South Pacific Gyre (26° 29′ S 137° 56′ W) during the Integrated Ocean Drilling Program Expedition 329. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain was related most closely to Aquimarina muelleri KMM 6020T, Aquimarina macrocephali JAMB N27T, Aquimarina addita JC2680T, Aquimarina mytili PSC33T, Aquimarina intermedia KMM 6258T, Aquimarina latercula ATCC 23177T, Aquimarina spongiae A6T, Aquimarina agarilytica ZC1T and Aquimarina brevivitae SMK-19T (96.1, 95.5, 95.0, 94.4, 94.3, 94.0, 93.4, 93.3 and 93.2 % similarities, respectively), demonstrating that the novel strain belonged to the genus Aquimarina . The DNA G+C content of strain SW024T was 30.8 mol%. The major respiratory quinone of strain SW024T was MK-6. The dominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G, C16 : 0 10-methyl and/or iso-C17 : 1ω9c, and iso-C15 : 0 3-OH. The polar lipids of strain SW024T were phosphatidylethanolamine, three unknown aminolipids and five unknown polar lipids. On the basis of combined phenotypic and phylogenetic analyses, strain SW024T represents a novel species of the genus Aquimarina , for which the name Aquimarina longa sp. nov. is proposed. The type strain is SW024T ( = CGMCC 1.11007T = JCM 17859T). An emended description of A. muelleri is also proposed.

Ochotona Curzoniae

Two Gram-stain-negative, strictly aerobic, bright-yellow-pigmented and rod-shaped bacteria (strains 100069 and 100111T) with a single polar flagellum were isolated from the rectal contents of plateau pika (Ochotona curzoniae). Based on the results of nearly full-length 16S rRNA gene sequence and phylogenetic analyses, strains 100069 and 100111T belong to the genus Luteimonas , and are closest to Luteimonas rhizosphaerae 4-12T (98.02 % similarity), Luteimonas aestuarii B9T (97.8 %) and Luteimonas terrae THG-MD21T (97.74 %). The DNA G+C contents of these two isolates were 68.30 mol% and 68.29 mol%, respectively. The highest average nucleotide identity (ANI) value between strain 100111T and its closely related species was 83.34 %, well below the threshold of 95–96 %. The major cellular fatty acids were iso-C11 : 0, iso-C15 : 0 and iso-C17 : 1  ω9. Polar lipid content was dominated by diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid and an unidentified lipid. Ubiquinone-8 (Q-8) was the predominant respiratory quinone. These two isolates grew optimally at 35–37 °C, pH 7.0–8.0 and with 1.0 % (w/v) NaCl. The results of ANI analysis and other characteristics obtained from our polyphasic study showed that strains 100069 and 100111T represent a novel species in genus Luteimonas , for which the name Luteimonas chenhongjianii sp. nov. (type strain 100111T=DSM 104077T=CGMCC 1.16429T) is proposed.
