A yellow-coloured, rod-shaped, Gram-reaction- and Gram-staining-negative, non-motile and aerobic bacterium, designated strain ZS1-8T, was isolated from a sample of sandy intertidal sediment collected from the Antarctic coast. Flexirubin-type pigments were absent. In phylogenetic analyses based on 16S rRNA gene sequences, strain ZS1-8T formed a distinct phyletic line and the results indicated that the novel strain should be placed in a new genus within the family Flavobacteriaceae . In pairwise comparisons between strain ZS1-8T and recognized species, the levels of 16S rRNA gene sequence similarity were all <93.3 %. The strain required Ca2+ and K+ ions as well as NaCl for growth. Optimal growth was observed at pH 7.5–8.0, 17–19 °C and with 2–3 % (w/v) NaCl. The major fatty acids were iso-C15 : 1 G, iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), an unknown acid with an equivalent chain-length of 13.565 and iso-C17 : 0 3-OH. The major respiratory quinone was MK-6. The predominant polar lipid was phosphatidylethanolamine. The genomic DNA G+C content was 43.9 mol%. Based on the phylogenetic, phenotypic and chemotaxonomic data, strain ZS1-8T represents a novel species in a new genus in the family Flavobacteriaceae for which the name Pricia antarctica gen. nov., sp. nov. is proposed. The type strain of the type species is ZS1-8T ( = JCM 17291T = DSM 23421T).

A Gram-staining-negative, non-flagellated, non-gliding and pleomorphic bacterial strain, designated DPG-25T, was isolated from seawater in a seaweed farm in the South Sea in Korea and its taxonomic position was investigated by using a polyphasic approach. Strain DPG-25T grew optimally at 25 °C, at pH 7.0–7.5 and in the presence of 2 % (w/v) NaCl. Flexirubin-type pigments were not produced. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DPG-25T formed a cluster with the type strains of Actibacter sediminis , Aestuariicola saemankumensis and Lutimonas vermicola . Strain DPG-25T exhibited 16S rRNA gene sequence similarity values of 95.3, 93.1 and 93.6 % to the type strains of Actibacter sediminis , Aestuariicola saemankumensis and L. vermicola , respectively. Strain DPG-25T contained MK-6 as the predominant menaquinone and iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain DPG-25T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content was 39.9 mol%. Differential phenotypic properties and the phylogenetic distinctiveness of strain DPG-25T demonstrated that this strain is distinguishable from Actibacter sediminis , Aestuariicola saemankumensis and L. vermicola . On the basis of the data presented here, strain DPG-25T represents a novel species in a novel genus of the family Flavobacteriaceae , for which the name Namhaeicola litoreus gen. nov., sp. nov. is proposed. The type strain of Namhaeicola litoreus is DPG-25T ( = KCTC 23702T  = CCUG 61485T).

A Gram-negative, obligately anaerobic, non-spore-forming, long rod-shaped bacterium strain P2T was isolated from the offshore mangrove sediment of the South China Sea. Growth was observed at between 22 and 39 °C, with an optimum at 35 °C. The pH range for growth was 5.0–8.5, with an optimum around pH 7.0–7.5. Salt tolerance was determined between 0.2 and 3.5 % (w/v), optimum at 0.5–1.0 %. Catalase and oxidase activities were negative. Strain P2T utilized cysteine, lactate, pyruvate, yeast extract or H2/CO2+acetate as electron donors, and sulfate or sulfite as electron acceptors. Metabolism was strictly fermentative. The main organic fermentation products were propionate, acetate and succinate. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain P2T formed a distinct evolutionary lineage within the family Marinilabiliaceae . Strain P2T was most closely related to members of the genera Alkaliflexus (92.0 % 16S rRNA gene sequence similarity), Marinilabilia (91.7 %) and Anaerophaga (89.9 %) of the family Marinilabiliaceae . The DNA G+C content of the novel strain was 44.2±1.0 mol%. The dominant fatty acids of strain P2T were iso-C15 : 0 (33.5 %), anteiso-C15 : 0 (18.9 %), C16 : 0 (5.4 %), C16 : 0 3-OH (7.7 %) and iso-C17 : 0 3-OH (13.3 %). The respiratory quinone was menaquinone 7 (100 % of total quinone) and the major polar lipid was phosphatidylethanolamine. Strain P2T was distinguishable from members of phylogenetically related genera by differences in several phenotypic properties. On the basis of phylogenetic, phenotypic and physiological evidence, a novel genus, Mangroviflexus, is proposed to harbour strain P2T ( = CGMCC 1.5167T = DSM 24214T) which is described as the type strain of a novel species, Mangroviflexus xiamenensis gen. nov., sp. nov.

Strains RU-16T, RU-28, RU-04T and PU-02T were isolated from the gut of the African mole cricket, Gryllotalpa africana. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strains belonged to the family Microbacteriaceae . All four strains were most closely related to Curtobacterium ginsengisoli DCY26T (below 97 % 16S rRNA gene sequence similarity). These isolates were Gram-stain-positive, motile (by gliding), rod-shaped and exhibited ivory-coloured colonies. Their chemotaxonomic properties included MK-11 as the major respiratory quinone, ornithine as the cell-wall diamino acid, acetyl as the acyl type of the peptidoglycan, cyclohexyl-C17 : 0 as the major fatty acid and phosphatidylglycerol and diphosphatidylglycerol as the major polar lipids. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, we propose a new genus in the family Microbacteriaceae , Gryllotalpicola gen. nov., with three novel species, Gryllotalpicola daejeonensis sp. nov. (type strain RU-04T  = KCTC 13809T  = JCM 17590T), Gryllotalpicola koreensis sp. nov. (type strain RU-16T  = KCTC 13810T  = JCM 17591T) and Gryllotalpicola kribbensis sp. nov. (type strain PU-02T  = KCTC 13808T  = JCM 17593T). Gryllotalpicola koreensis is the type species of the genus. Additionally, we propose that Curtobacterium ginsengisoli should be reclassified in the genus as Gryllotalpicola ginsengisoli comb. nov. (type strain DCY26T  = KCTC 13163T  = JCM 14773T).

A Gram-stain-negative, aerobic, yellow, non-motile, rod-shaped and alginate-degrading bacterium, designated Dm15T, was isolated from marine alga collected in Weihai, PR China. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Dm15T represents a distinct line of the family Flavobacteriaceae . Strain Dm15T had the highest 16S rRNA gene sequence similarity to its closest phylogenetic neighbour Arcticiflavibacter luteus (96.7 %) and 93.7–96.4 % sequence similarity to other phylogenetic neighbours ( Bizionia paragorgiae , Winogradskyella thalassocola , Ichthyenterobacterium magnum , Psychroserpens burtonensis and Arcticiflavibacter luteus ) in the family Flavobacteriaceae . The novel isolate was able to grow at 10–40 °C (optimum, 30–33 °C), pH 7.0–9.0 (optimum, pH 7.0–7.5) and with 0.5–6.0 % NaCl (optimum 2.0–3.0 %, w/v). It could grow at 40 °C, and degrade alginate and cellulose, which were different from the neighbour genera. The draft genome consisted of 3395 genes with a total length of 3 798 431 bp and 34.1mol% G+C content. Especially, there were some specific genes coding for cellulase and alginate lyase, which provided a basis for the above phenotypic characteristics. The strain's genome sequence showed 71.1–80.2 % average amino acid identity values and 71.8–77.7 % average nucleotide identity values compared to the type strains of related genera within the family Flavobacteriaceae . It shared digital DNA–DNA hybridization identity of 19.8 and 20.9 % with I. magnum and A. luteus , respectively. The sole menaquinone was MK-6. The major fatty acids were iso-C15 : 0 and iso-C15 : 1 G. The polar lipids included six unidentified polar lipids, four unidentified aminolipids and phosphatidylethanolamine. Based on the results of phenotypic, chemotaxonomic and phylogenetic analyses, strain Dm15T represents a novel species of a new genus in the family Flavobacteriaceae , phylum Bacteroidetes , for which the name Flavihalobacter algicola gen. nov., sp. nov. is proposed. The type strain is Dm15T (KCTC 42256T=CICC 23815T).
