A group of nine Gram-negative staining, facultatively anaerobic bacterial strains isolated from native oak trees displaying symptoms of acute oak decline (AOD) in the UK were investigated using a polyphasic approach. 16S rRNA gene sequencing and phylogenetic analysis revealed that these isolates form a distinct lineage within the genus Brenneria , family Enterobacteriaceae , and are most closely related to Brenneria rubrifaciens (97.6 % sequence similarity to the type strain). Multilocus sequence analysis based on four housekeeping genes (gyrB, rpoB, infB and atpD) confirmed their position within the genus Brenneria , while DNA–DNA hybridization indicated that the isolates belong to a single taxon. The isolates can be differentiated phenotypically from their closest phylogenetic neighbours. The phylogenetic and phenotypic data demonstrate that these isolates from oak with symptoms of AOD represent a novel species in the genus Brenneria , for which the name Brenneria goodwinii sp. nov. (type strain FRB 141T  = R-43656T  = BCC 845T  = LMG 26270T  = NCPPB 4484T) is proposed.

Two Gram-stain-negative, aerobic, non-motile bacterial strains, 36D10-4-7T and 30C10-4-7T, were isolated from bark canker tissue of Populus × euramericana, respectively. 16S rRNA gene sequence analysis revealed that strain 36D10-4-7T shows 98.0 % sequence similarity to Sphingomonas adhaesiva DSM 7418T, and strain 30C10-4-7T shows highest sequence similarity to Sphingobacterium arenae H-12T (95.6 %). Average nucleotide identity analysis indicates that strain 36D10-4-7T is a novel member different from recognized species in the genus Sphingomonas . The main fatty acids and respiratory quinone detected in strain 36D10-4-7T are C18 : 1  ω7c and/or C18 : 1  ω6c and Q-10, respectively. The polar lipids are diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, aminolipid, phosphatidylethanolamine, sphingoglycolipid, two uncharacterized phospholipids and two uncharacterized lipids. For strain 30C10-4-7T, the major fatty acids and menaquinone are iso-C15 : 0, C16 : 1  ω7c and/or C16 : 1  ω6c and iso-C17 : 0 3-OH and MK-7, respectively. The polar lipid profile includes phosphatidylethanolamine, phospholipids, two aminophospholipids and six unidentified lipids. Based on phenotypic and genotypic characteristics, these two strains represent two novel species within the genera Sphingomonas and Sphingobacterium . The name Sphingomonas corticis sp. nov. (type strain 36D10-4-7T=CFCC 13112T=KCTC 52799T) and Sphingobacterium corticibacterium sp. nov. (type strain 30C10-4-7T=CFCC 13069T=KCTC 52797T) are proposed.

A strictly aerobic, bacteriochlorophyll (BChl) a-containing alphaproteobacterium, designated strain K6T, was isolated from seawater around an aquaculture site in the Uwa Sea in Japan. The novel strain grew optimally at 30 °C at pH 7.0–7.5 and in the presence of 2.0 % (w/v) NaCl. The nonmotile and coccoid or rod-shaped cells formed pink-pigmented colonies on agar plates containing organic compounds. Cells showed an in vivo absorption maximum at 870 nm in the near-infrared region, indicating the presence of BChl a in the light-harvesting 1 complex. The new bacterial strain was Gram-stain-negative and oxidase- and catalase-positive. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain K6T was closely related to species in the genus Litoreibacter . The closest phylogenetic relatives of strain K6T were Litoreibacter ponti GJSW-31T (98.56 % sequence similarity), Litoreibacter janthinus KMM 3842T (97.63 %) and Litoreibacter albidus KMM 3851T (96.88 %). The G+C content of the genomic DNA was 58.26 mol%. The average nucleotide identity value of strain K6T with the type strain of L. ponti was 77.16 % (SD 4.79 %). The digital DNA−DNA hybridization value of strain K6T with the type strain of L. ponti was 19.40 %. The respiratory quinone was ubiquinone-10. The major cellular fatty acids were C18 : 1 ω7c, C16 : 0 and 11-methyl C18 : 1 ω7c. The dominant polar lipids were phosphatidylcholine and phosphatidylglycerol. On the basis of the genetic and phenotypic data obtained in the present study, we propose a new species in the genus Litoreibacter : Litoreibacter roseus sp. nov., whose type strain is K6T (=DSM 110109T=NBRC 114114T). Strain K6T represents the first confirmed species that produces BChl a within the genus Litoreibacter .

A coccal-shaped organism, designated 516T, was isolated from yan-tsai-shin (fermented broccoli stems), a traditional fermented food in Taiwan. 16S rRNA gene sequencing results showed that strain 516T had 98.9 % sequence similarity to that of the type strain Lactococcus garvieae NBRC 100934T. Comparison of three housekeeping genes, rpoA, rpoB and pheS, revealed that strain 516T was well separated from Lactococcus garvieae NBRC 100934T. DNA–DNA hybridization studies indicated that strain 516T had low DNA relatedness with Lactococcus garvieae NBRC 100934T (46.1 %). The DNA G+C content of strain 516T was 38.1 mol% and the major fatty acids were C16 : 0 (22.7 %), C19 : 0 cyclo ω8c (17.9 %) and summed feature 7 (29.0 %). Based on the evidence, strain 516T represents a novel species of the genus Lactococcus , for which the name Lactococcus formosensis sp. nov. is proposed. The type strain is 516T ( = NBRC 109475T = BCRC 80576T).

Four Gram-stain-negative, aerobic, rod-shaped bacterial strains, MM-124, MM-126, NB-68 and NB-77, were isolated from the coastal seawater or a region with a bloom of sea sparkle around Geoje island in Korea. The sequence similarity values of the 16S rRNA gene between the isolates and Sulfitobacter mediterraneus DSM 12244T ranged from 97.7 to 98.2 %, and phylogenetic relationships suggested that they belong to a phylogenetic branch that includes the genera Sulfitobacter and Roseobacter . The isoprenoid quinone of all three novel strains was ubiquinone-10 and the major fatty acid was cis-vaccenic acid, as in other species of the genus Sulfitobacter . However, there were several differences in the morphological, physiological and biochemical characteristics among the four strains and the reference species of the genus Sulfitobacter . Moreover, the average nucleotide identity values between the three sequenced isolates and the reference strains were below 76.33, indicating that genomic variation exists between the isolates and reference strains. Chemotaxonomic characteristics together with phylogenetic affiliations and genomic distances illustrate that strains MM-124, NB-68 and NB-77 represent novel species of the genus Sulfitobacter , for which the names Sulfitobacter geojensis sp. nov. (type strain MM-124T = KCTC 32124T = JCM 18835T), Sulfitobacter noctilucae sp. nov. (type strain NB-68T = KCTC 32122T = JCM 18833T) and Sulfitobacter noctilucicola sp. nov.

A second novel clinical actinobacterial strain, designated IFM 10348T, was isolated from the sputum of the same Japanese patient with bacterial pneumonia from whom the type strain of Gordonia araii had been isolated. The strains differed in phylogenetic position and drug-resistance profiles. The taxonomic position of strain IFM 10348T was clarified by phenotypic, chemotaxonomic and phylogenetic studies. Phylogenetic analyses based on 16S rRNA gene sequences clearly demonstrated that strain IFM 10348T occupied a distinct clade within the genus Gordonia and was related closely to Gordonia malaquae DSM 45064T and Gordonia hirsuta DSM 44140T (97.3 and 97.1 % similarities, respectively). Strain IFM 10348T was also clearly differentiated from G. malaquae DSM 45064T and G. hirsuta DSM 44140T based on gyrB and secA1 gene sequence similarity values. Strain IFM 10348T had MK-9(H2) as the predominant menaquonine, contained meso-diaminopimelic acid, arabinose, galactose and glucosamine as cell-wall components, and contained C18 : 1ω9c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the major cellular fatty acids. Mycolic acids were present. The DNA G+C content of strain IFM 10348T was 68.0 mol%. DNA–DNA relatedness data coupled with the combination of genotypic and phenotypic data indicated that strain IFM 10348T represents a novel species of the genus Gordonia , for which the name Gordonia iterans sp. nov. is proposed. The type strain is IFM 10348T ( = CCTCC M2011245T = NCCB 100436T).

A taxonomic study was carried out on strain PA15-N-34T, which was isolated from deep-sea sediment of Pacific Ocean. The bacterium was Gram-stain-positive, oxidase- and catalase-positive and rod-shaped. Growth was observed at salinity of 0–15.0% NaCl and at temperatures of 10–45 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PA15-N-34T belonged to the genus Alcanivorax , with the highest sequence similarity to Alcanivorax profundi MTEO17T (97.7 %), followed by Alcanivorax nanhaiticus 19 m-6T (97.3 %) and 12 other species of the genus Alcanivorax (93.4 %–97.0 %). The average nucleotide identity and DNA–DNA hybridization values between strain PA15-N-34T and type strains of the genus Alcanivorax were 71.46–81.78% and 18.7–25.2 %, respectively. The principal fatty acids (>10 %) were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c; 31.2 %), C16 : 0 (25.0 %) and summed feature 3 (14.6 %). The DNA G+C content was 57.15 mol%. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, four unidentified aminolipids and three unidentified lipids. The novel strain can be differentiated from its closest type strain by a negative test for urease and the presence of diphosphatidylglycerol and aminolipid. The combined genotypic and phenotypic data show that strain PA15-N-34T represents a novel species within the genus Alcanivorax , for which the name Alcanivorax sediminis sp. nov. is proposed, with the type strain PA15-N-34T (=MCCC 1A14738T=KCTC 72163T).
