A pink-pigmented, Gram-stain-negative, rod-shaped, strictly aerobic bacterial strain MIMtkB3T, was isolated from moss crusts in Hunshandake desert of China. Cells grew at 15–45 °C (optimum of 28 °C), at pH of 6.0–8.5 (optimum of 7.0) and with 0–1.0 % (w/v) NaCl (optimum of 0 %). The strain could biosynthesize the green-coloured pigment bacteriochlorophyll a (BChl a). The respiratory quinone was ubiquinone Q-10, while C18 : 1 ω7c and C18 : 1 2OH were the major fatty acids. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified aminophospholipid, one unidentified phospholipid, three unidentified glycolipid and one unidentified lipid were the major polar lipids. Strain MIMtkB3T was most closely related to Oleisolibacter albus NAU-10T, Niveispirillum fermenti CC-LY736T, and Rhodocista centenaria SW of the family Rhodospirillaceae with 16S rRNA gene similarities of 93.09, 92.02 and 91.73%, respectively. The genomic DNA G+C content calculated on complete genome sequencing was 69.3 mol%. The average nucleotide identity between strain MIMtkB3T and its closely related type strains in Rhodospirillaceae was below 77.96 % and digital DNA–DNA hybridization lower than 24.70 %. Full light utilization pathway of aerobic anoxygenic phototrophic bacteria was identified in the genome. Based on phenotypic, chemotaxonomic and phylogenetic characteristics, strain MIMtkB3T represents a novel genus of the family Rhodospirillaceae , for which the name Aerophototrophica crusticola gen. nov., sp. nov. is proposed. The type strain is MIMtkB3T (=KCTC 42633T=MCCC 1K00570T).

A Gram-stain-negative, rod-shaped and facultatively aerobic bacterial strain, designated F7430T, was isolated from coastal sediment collected at Jingzi Wharf in Weihai, PR China. Cells of strain F7430T were 0.3–0.4 µm wide, 2.0–2.6 µm long, non-flagellated, non-motile and formed pale-beige colonies. Growth was observed at 4–40 °C (optimum, 30 °C), pH 6.0–9.0 (optimum, pH 7.5–8.0) and at NaCl concentrations of 1.0–10.0 % (w/v; optimum, 1.0 %). The sole respiratory quinone of strain F7430T was ubiquinone 8 and the predominant cellular fatty acids were summed feature 8 (C18 : 1  ω7c / C18 : 1  ω6c; 60.7 %), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c; 30.2 %) and C15 : 0 iso (13.9 %). The polar lipids of strain F7430T consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one unidentified phospholipid and three unidentified lipids. Results of 16S rRNA gene sequences analyses indicated that this strain belonged to the family Halieaceae and had high sequence similarities to Parahaliea aestuarii JCM 51547T (95.3 %) and Halioglobus pacificus DSM 27932T (95.2 %) followed by 92.9–95.0 % sequence similarities to other type species within the aforementioned family. The rpoB gene sequences analyses indicated that the novel strain had the highest sequence similarities to Parahaliea aestuarii JCM 51547T (82.2 %) and Parahaliea mediterranea DSM 21924T (82.2 %) followed by 75.2–80.5 % sequence similarities to other type species within this family. Phylogenetic analyses showed that strain F7430T constituted a monophyletic branch clearly separated from the other genera of family Halieaceae . Whole-genome sequencing of strain F7430T revealed a 3.3 Mbp genome size with a DNA G+C content of 52.6 mol%. The genome encoded diverse metabolic pathways including the Entner–Doudoroff pathway, assimilatory sulphate reduction and biosynthesis of dTDP-l-rhamnose. Based on results from the current polyphasic study, strain F7430T is proposed to represent a novel species of a new genus within the family Halieaceae , for which the name Sediminihaliea albiluteola gen. nov., sp. nov. is proposed. The type strain of the type species is F7430T (=KCTC 72873T=MCCC 1H00420T).

The taxonomic position of bacterial strain AM11-6T, isolated from seawater in Japan, was determined by using a polyphasic taxonomic approach. The strain was a strictly aerobic and Gram-staining-negative slender rod, motile by gliding. The major respiratory quinone was menaquinone-6 and the predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, C14 : 0 and iso-C15 : 1 G. The polar lipid pattern indicated the presence of an unidentified phospholipid, several glycolipids and an unidentified polar lipid. The G+C content of the genomic DNA was 36.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain AM11-6T clustered with members of the genera Wandonia and Fluviicola in the family Cryomorphaceae of the phylum Bacteroidetes . The strain required NaCl and MgCl2 for growth and could be differentiated from members of other genera in the family Cryomorphaceae by fatty acid composition and other phenotypic characters. On the basis of these results, we describe the novel genus and species, Salinirepens amamiensis gen. nov., sp. nov. The type strain of Salinirepens amamiensis is AM11-6T ( = NBRC 101268T = NCIMB 14607T). Emended descriptions of the genera Fluviicola and Wandonia are also proposed.

Emended Description

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.
