Three bacterial isolates from air samples in Korea, designated strains 6424S-25T, 6515J-31T and 6424S-61T, were characterized using a polyphasic approach. The cells were strictly aerobic, Gram-stain-negative, non-motile, non-spore-forming and rod-shaped. Phylogenetic analysis of their 16S rRNA gene sequences revealed a clear affiliation with the phylum Bacteroidetes. Strains 6424S-25T and 6515J-31T showed 16S rRNA gene sequence similarities of 92.7–94.8 % to type strains of recognized species of the genus Adhaeribacter and strain 6424S-61T was closely related to Segetibacter koreensis Gsoil 664T (93.9 % similarity). The G+C contents of the DNA of strains 6424S-25T, 6515J-31T and 6424S-61T were 44.5, 43.9 and 38.4 mol%, respectively. Major fatty acids of strains 6424S-25T and 6515J-31T were summed feature 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B), iso-C15 : 0 and C16 : 1 ω5c. The fatty acid content of strain 6424S-61T mainly comprised iso-C15 : 1 G and iso-C15 : 0. Comparative analysis of phenotypic and phylogenetic traits indicated that strains 6424S-25T and 6515J-31T represented two novel species of the genus Adhaeribacter and that strain 6424S-61T should be considered as a novel species of the genus Segetibacter. The names Adhaeribacter aerophilus sp. nov. (type strain 6424S-25T =KACC 14118T =NBRC 106134T), Adhaeribacter aerolatus sp. nov. (type strain 6515J-31T =KACC 14117T =NBRC 106133T) and Segetibacter aerophilus sp. nov. (type strain 6424S-61T =KACC 14119T =NBRC 106135T) are proposed for these organisms.

A Gram-negative, aerobic, rod-shaped, non-motile bacterium, designated BZ42T, was isolated from the soil of an industrial site. Strain BZ42T was able to grow at 5–25 °C. The major fatty acids were iso-C15 : 0 (46.2 %), C16 : 1 ω7c and/or iso-C15 : 0 2-OH (23.2 %) and iso-C17 : 0 3-OH (9.1 %). The predominant menaquinone was MK-7. The genomic DNA G+C content was 36.5 mol% (HPLC). 16S rRNA gene sequence phylogenetic analysis revealed that strain BZ42T was a member of the genus Pedobacter, family Sphingobacteriaceae, and 16S rRNA gene sequence similarities between strain BZ42T and the type strains of species of the genus Pedobacter with validly published names were 90.4–93.2 %. On the basis of phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain BZ42T was considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter bauzanensis sp. nov. is proposed. The type strain is BZ42T (=DSM 22554T =CGMCC 1.10187T =CIP 110134T).

Two anaerobic, non-spore-forming, non-motile, Gram-negative-staining bacteria, strains YIT 12060T and YIT 12061T, were isolated from human faeces. Cells of strain YIT 12060T were coccoid to rod-shaped with round ends, positive for catalase, negative for indole and oxidase production, produced succinic and acetic acids as end products of glucose metabolism in peptone/yeast extract/glucose medium and had a DNA G+C content of 55.2 mol%. The main respiratory quinones were MK-10 (40 %) and MK-11 (57 %). Fatty acid analysis demonstrated the presence of a high concentration of iso-C15 : 0 (56 %). Following 16S rRNA gene sequence analysis, this strain was found to be most closely related to species of the genus Alistipes, with 90.9–92.6 % gene sequence similarities to type strains of this species. Phylogenetic analysis and biochemical data supported the affiliation of strain YIT 12060T to the genus Alistipes of the family ‘Rikenellaceae’. Strain YIT 12060T therefore represents a novel species of the genus Alistipes for which the name Alistipes indistinctus sp. nov. is proposed; the type strain is YIT 12060T (=DSM 22520T=JCM 16068T). Cells of the other isolate, strain YIT 12061T, were pleomorphic rods that were asaccharolytic, catalase- and oxidase-negative, positive for gelatin hydrolysis and indole production, produced small amounts of succinic, acetic and iso-valeric acids as end products of metabolism in peptone/yeast extract medium and had a DNA G+C content of approximately 42.4 mol%. On the basis of 16S rRNA gene sequence similarity values, this strain was shown to belong to the family ‘Porphyromonadaceae’ and related to the type strains of Odoribacter splanchnicus (89.6 %) and Odoribacter denticanis (86.2 %); similarity values with strains of recognized species within the family ‘Porphyromonadaceae’ were less than 84 %. Biochemical data supported the affiliation of strain YIT 12061T to the genus Odoribacter. Strain YIT 12061T therefore represents a novel species for which the name Odoribacter laneus sp. nov. is proposed; the type strain is YIT 12061T (=DSM 22474T=JCM 16069T).

Four novel bacterial strains were isolated from cryogenic tubes used to collect air samples at altitudes of 24, 28 and 41 km. The four strains, 24KT, 28KT, 41KF2aT and 41KF2bT, were identified as members of the genus Bacillus. Phylogenetic analysis based on 16S rRNA gene sequences indicated that three of the strains, 24KT, 28KT and 41KF2aT, are very similar to one another (>98 % sequence similarity) and show a similarity of 98–99 % with Bacillus licheniformis and 98 % with Bacillus sonorensis. DNA–DNA hybridization studies showed that strains 24KT, 28KT and 41KF2aT exhibit <70 % similarity with each other and with B. licheniformis and B. sonorensis. Differences in phenotypic and chemotaxonomic characteristics between the novel strains and B. licheniformis and B. sonorensis further confirmed that these three isolates are representatives of three separate novel species. Strain 41KF2bT showed 100 % 16S rRNA gene sequence similarity to Bacillus pumilus, but differed from its nearest phylogenetic neighbour in a number of phenotypic and chemotaxonomic characteristics and showed only 55 % DNA–DNA relatedness. Therefore, the four isolates represent four novel species for which the names Bacillus aerius sp. nov. (type strain, 24KT=MTCC 7303T=JCM 13348T), Bacillus aerophilus sp. nov. (type strain, 28KT=MTCC 7304T=JCM 13347T), Bacillus stratosphericus sp. nov. (type strain, 41KF2aT=MTCC 7305T=JCM 13349T) and Bacillus altitudinis sp. nov. (type strain, 41KF2bT=MTCC 7306T=JCM 13350T) are proposed.

A Gram-negative, non-pigmented, non-motile, chemoheterotrophic marine bacterium, designated strain IMCC2782T, was isolated from a surface seawater sample of the Yellow Sea, Korea. On the basis of 16S rRNA gene sequence analysis and phenotypic and genotypic characterization, strain IMCC2782T is shown to represent a novel species of the genus Litoricola. Strain IMCC2782T grew at 15–37 °C and tolerated 7.5 % NaCl. Based on 16S rRNA gene sequences, strain IMCC2782T was related most closely to the type strain of Litoricola lipolytica (97.1 % similarity) but showed less than 90 % similarity to the type strains of other bacterial species. The predominant fatty acids were mono-unsaturated C18 : 1 and C16 : 1. The G+C content of the DNA of strain IMCC2782T was 59.6 mol%. A low level of DNA–DNA relatedness (28.1 %) together with several phenotypic characteristics, including enzyme activities, served to differentiate strain IMCC2782T from the type strain of L. lipolytica. Therefore, strain IMCC2782T is considered to represent a novel species of the genus Litoricola, for which the name Litoricola marina sp. nov. is proposed. The type strain is IMCC2782T (=KCTC 22683T =NBRC 105824T).

Ten strains previously assigned to Acetobacter hansenii (=Gluconacetobacter hansenii), Acetobacter pasteurianus LMG 1584 and eight reference strains of the genus Gluconacetobacter were reclassified by 16S rRNA gene sequencing, DNA–DNA similarity, DNA base composition and phenotypic characteristics. The A. hansenii strains and A. pasteurianus LMG 1584 were included in the cluster of acetic acid bacteria (family Acetobacteraceae) by 16S rRNA gene sequences. Further, they were separated into seven distinct groups by DNA–DNA similarity. DNA–DNA similarity group I was identified as G. hansenii. DNA–DNA similarity group II was retained as Gluconacetobacter sp., because DNA–DNA similarity between the strain and Gluconacetobacter entanii LTH 4560T could not be determined. This was due to a lack of availability of the type strain from any source. DNA–DNA similarity group III was regarded as a novel species, for which the name Gluconacetobacter saccharivorans sp. nov. (type strain, LMG 1582T=NRIC 0614T) is proposed. DNA–DNA similarity group IV included the type strains of Gluconacetobacter oboediens and Gluconacetobacter intermedius, and three A. hansenii strains. This group was identified as G. oboediens because high values of DNA–DNA similarity were obtained between the type strains and G. oboediens has priority over G. intermedius. DNA–DNA similarity group V was identified as Gluconacetobacter europaeus. DNA–DNA similarity group VI was regarded as a novel species, for which the name Gluconacetobacter nataicola sp. nov. (type strain, LMG 1536T=NRIC 0616T) is proposed. DNA–DNA similarity group VII was reclassified as Gluconacetobacter xylinus. The description of G. hansenii is emended.

A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and coccoid, ovoid or rod-shaped bacterial strain, designated AH-M8T, was isolated from a tidal flat sediment collected from Aphae Island in the south-western sea, South Korea. Strain AH-M8T grew optimally at 35 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0  % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain AH-M8T belonged to the genus Sphingomicrobium, clustering with the type strain of Sphingomicrobium astaxanthinifaciens, with which it shared 99.0 % 16S rRNA gene sequence similarity. Sequence similarities to the type strains of other species of the genus Sphingomicrobium were 95.4–96.0  %. Strain AH-M8T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the major fatty acids. The major polar lipids of strain AH-M8T were phosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and one unidentified glycolipid. The major polyamine is triamine sym-homospermidine. The DNA G+C content of strain AH-M8T was 66.7 mol% and its mean DNA–DNA relatedness value with S. astaxanthinifaciens JCM 18551T was 21  %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain AH-M8T is separated from other species of the genus Sphingomicrobium. On the basis of the data presented, strain AH-M8T is considered to represent a novel species of the genus Sphingomicrobium, for which the name Sphingomicrobium aestuariivivum sp. nov. is proposed. The type strain is AH-M8T ( = KCTC 42286T = NBRC 110678T).

A non-motile, red-pigmented bacterium, designated strain HMD1010T, was isolated from an artificial lake located within the campus of Hankuk University of Foreign Studies, Yongin, Korea. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD1010T formed a lineage within the genus Hymenobacter and was closely related to the type strains of Hymenobacter rigui (96.7 % sequence similarity) and H. gelipurpurascens (95.6 %). The major fatty acids were C16 : 1ω5c (21.9 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c; 17.2 %), iso-C15 : 0 (14.5 %) and summed feature 4 (anteiso-C17 : 1 B and/or iso-C17 : 1 I; 11.9 %). The DNA G+C content was 60.4 mol%. On the basis of the evidence presented in this study, strain HMD1010T represents a novel species of the genus Hymenobacter, for which the name Hymenobacter yonginensis sp. nov. was proposed.

A novel strain, designated KP01T, belonging to the class Sphingobacteria (phylum Bacteroidetes) was isolated from soil in South Korea and was characterized taxonomically using a polyphasic approach. The strain was found to comprise Gram-negative, aerobic, non-motile, non-spore-forming rods. A phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Chitinophaga but was clearly separated from established Chitinophaga species. The 16S rRNA gene sequence similarities between KP01T and type strains of established Chitinophaga species ranged from 90.3 to 95.7 %. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; major fatty acids, iso-C15 : 0 and C16 : 1 ω5c; major hydroxy fatty acid, C17 : 0 iso 3-OH) supported the affiliation of strain KP01T with the genus Chitinophaga. Therefore strain KP01T represents a novel species, for which the name Chitinophaga terrae sp. nov. is proposed. The type strain is KP01T (=KCTC 12836T =LMG 24015T).

A Gram-stain-negative, strictly aerobic, non-pigmented, motile bacterium with a single polar flagellum, designated H29T, was isolated from coastal sediment of Jeju Island, South Korea. Cells were non-spore-forming rods showing catalase- and oxidase-positive reactions. Growth of strain H29T was observed at 10–40 °C (optimum, 20–25 °C) and pH 6.0–9.0 (optimum, pH 7.0–8.0), and in the presence of 1–4 % (w/v) NaCl (optimum, 2–3 %). Strain H29T contained C16 : 0, iso-C15 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c/C16 : 1ω6c) as the major fatty acids and ubiquinone-8 (Q-8) as the sole isoprenoid quinone. Phosphatidylethanolamine and phosphatidylglycerol were identified as the major polar lipids. The G+C content of the genomic DNA was 46.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain H29T formed a phyletic lineage with Rheinheimera hassiensis E48T within the genus Rheinheimera of the family Chromatiaceae. Strain H29T was most closely related to Rheinheimera pacifica KMM 1406T, Rheinheimera muenzenbergensis E49T, Rheinheimera hassiensis E48T and Rheinheimera baltica OSBAC1T with 97.8 %, 97.6 %, 97.4 % and 97.2 % 16S rRNA gene sequence similarities, respectively. However, DNA–DNA hybridization values of strain H29T with type strains of these species were lower than 70 %. On the basis of the phenotypic, chemotaxonomic and molecular properties, strain H29T represents a novel species of the genus Rheinheimera, for which the name Rheinheimera aestuarii sp. nov. is proposed. The type strain is H29T ( = KACC 18251T = JCM 30404T).
