Two lactic acid-producing, Gram-stain-positive rods were isolated from a microbial mat actively growing in the littoral zone of an Antarctic lake (Forlidas Pond) in the Pensacola mountains and studied using a polyphasic taxonomic approach. The isolates were examined by phylogenetic analysis of the 16S rRNA gene, multilocus sequence analysis of pheS, rpoA and atpA, and biochemical and genotypic characteristics. One strain, designated LMG 26641, belonged to Carnobacterium alterfunditum and the other strain, designated LMG 26642T, could be assigned to a novel species, with Carnobacterium funditum DSM 5970T as its closest phylogenetic neighbour (99.2 % 16S rRNA gene sequence similarity). Carnobacterium iners sp. nov. could be distinguished biochemically from other members of the genus Carnobacterium by the lack of acid production from carbohydrates. DNA–DNA relatedness confirmed that strain LMG 26642T represented a novel species, for which we propose the name Carnobacterium iners sp. nov. (type strain is LMG 26642T  = CCUG 62000T).

Four unknown strains belonging to the genus Arthrobacter were isolated from plateau wildlife on the Qinghai–Tibet Plateau of PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four isolates were separated into two clusters. Cluster I (strains 785T and 208) had the greatest 16S rRNA gene sequence similarity to Arthrobacter citreus (98.6 and 98.7 %, respectively), Arthrobacter luteolus (98.0 and 98.1%, respectively), Arthrobacter gandavensis (97.9 and 98.0 %, respectively) and Arthrobacter koreensis (97.6 and 97.7 %, respectively). Likewise, cluster II (strains J391T and J915) had the highest sequence similarity to Arthrobacter ruber (98.6 and 98.3 %, respectively) and Arthrobacter agilis (98.1 and 97.9  %, respectively). Average nucleotide identity and the digital DNA–DNA hybridization values illustrated that the two type strains, 785T and J391T, represented two separate novel species that are distinct from all currently recognized species in the genus Arthrobacter . These strains had DNA G+C contents of 66.0–66.1 mol% (cluster I) and 68.0 mol% (cluster II). The chemotaxonomic properties of strains 785T and J391T were in line with those of the genus Arthrobacter : anteiso-C15:0 (79.3 and 40.8 %, respectively) as the major cellular fatty acid, MK-8(H2) (65.8 %) or MK-9(H2) (75.6 %) as the predominant respiratory quinone, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycolipids and phospholipid, and A3α or A4α as the cell wall peptidoglycan type. On the basis of our results, two novel species in the genus Arthrobacter are proposed, namely Arthrobacter yangruifuii sp. nov. (type strain, 785T=CGMCC 1.16725T=GDMCC 1.1592T=JCM 33491T) and Arthrobacter zhaoguopingii sp. nov. (type strain, J391T=CGMCC 1.17382T=GDMCC 1.1667T=JCM 33841T).

Clostridium Symbiosum

An obligately anaerobic, Gram-stain-positive and spore-forming strain, SNUG30386T was isolated from a faecal sample of a healthy Korean subject. The strain formed a round ivory-coloured colony and cells were chained rods with tapered ends, approximately 2.0–2.5×0.6–0.8 μm in size. The taxonomic analysis indicated that strain SNUG30386T was within the family Lachnospiraceae . According to the 16S rRNA gene sequence similarity, the closest species to strain SNUG30386T was Clostridium symbiosum (95.6 %), followed by Enterocloster asparagiformis (94.8 %), Enterocloster clostridioformis (94.8 %) and Enterocloster lavalensis (94.6 %). The evolutionary tree based on 16S rRNA gene sequences demonstrated that strain SNUG30386T had split apart at a unique branch point far from other close relatives. Its DNA G+C content was 48.3 mol% calculated from the whole genome sequence. The major cellular fatty acids were C16 : 0 and C14 : 0. Compared to those of the closely related species, strain SNUG30386T showed distinct biochemical activities such as being unable to utilize most of carbon sources except d-glucose and l-arabinose. As a result, based on its unique phylogenetic clade and taxonomic characteristics, we conclude that strain SNUG30386T represents a novel species within the genus Clostridium , for which the name Clostridium fessum sp. nov. is proposed. The type strain of the novel species is SNUG30386T (=KCTC 15633T= JCM 32258T).

A Gram-stain-negative, non-motile, red bacterium, designated DCY57T, was isolated from soil of a ginseng field in a mountainous region of Chungnam province in South Korea. Strain DCY57T grew with 0–1 % (w/v) NaCl and the optimum temperature for growth was 30 °C. Strain DCY57T contained MK-7 as the predominant menaquinone. The polyamine was sym-homospermidine. The major fatty acids were C16:1ω5c, iso-C15:0, anteiso-C15:0 and summed feature 3 (containing C16:1ω7c and/or C16:1ω6c). The major polar lipids were phosphatidylethanolamine, unknown aminophospholipids, unknown aminolipids and unknown lipids. The DNA G+C content was 58.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DCY57T was most closely related to members of the genus Hymenobacter . The isolate exhibited 91.7 % 16S rRNA gene sequence similarity with H. soli PB17T, 94.5 % with H. flocculans A2-50AT and 95.8 % with H. metalli A2-91T. On the basis of the evidence presented in this study, strain DCY57T represents a novel species within the genus Hymenobacter , for which the name Hymenobacter ginsengisoli sp. nov. is proposed. The type strain is DCY57T ( = KCTC 23674T = JCM 17841T).

Two strains (JA266T and JA333) of Gram-negative, rod-shaped, phototrophic, purple non-sulfur bacteria were isolated from a freshwater fish pond and an industrial effluent. Both strains were capable of phototrophic and chemotrophic growth. Bacteriochlorophyll a and carotenoids of the spirilloxanthin series were present as photosynthetic pigments. The major fatty acid for both strains was C18 : 1ω7c (>65 %), with minor amounts of 11-methyl C18 : 1ω7c, C16 : 0, C16 : 1ω7c and C18 : 0 also present. Both strains have the lamellar type of intracellular photosynthetic membranes. Ubiquinone-10 (Q10) and rhodoquinone-10 (RQ10) were present as primary quinone components. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine were the major polar lipids, while minor amounts of amino lipids (AL1, AL2) and an unidentified lipid (L1) were common to both strains. The DNA G+C contents of strains JA266T and JA333 were 71.3 and 69.9 mol%, respectively. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that both strains clustered with members of the genus Rhodoplanes in the class Alphaproteobacteria . Strains JA266T and JA333 had gene sequence similarity of 98.7 and 98.9 % with Rhodoplanes serenus TUT3530T, 96.4 and 96.5 % with Rhodoplanes elegans AS130T, respectively, and less than 96 % with other members of the genus Rhodoplanes . 16S rRNA gene sequence similarity between the two strains was 99.3 % and they exhibited high (84.7 %) relatedness based on DNA–DNA hybridization. Furthermore, both strains had less than 65 % DNA–DNA relatedness with the type strain R. serenus TUT3530T. On the basis of phenotypic and genotypic data, it is proposed that strain JA266T be classified as a novel species of the genus Rhodoplanes , with the species name Rhodoplanes piscinae sp. nov. The type strain of the proposed novel species is JA266T ( = JCM 14934T = KCTC 5627T), while strain JA333 ( = NBRC 107574 = KCTC 5962) is an additional strain.

Two Gram-negative, aerobic, motile bacteria strains were isolated from leaf spot disease of Quercus mongolica. Strain hsmgli-8T has 99.86 % 16S rRNA gene sequence similarity to LY10J, and the highest 16S rRNA gene sequence similarity to Pseudomonas cerasi 58T (97.2 %), then Pseudomonas ficuserectae JCM 2400T (97.18 %), Pseudomonas meliae CFBP 3225T, Pseudomonas tremae CFBP 6111T and Pseudomonas congelans DSM 14939T (all 97.12 %), and less than 97.1 % similarity to other recognized species. In phylogenetic trees based on 16S rRNA gene and multilocus sequence data, the two novel strains form a separate branch, indicating that they do not belong to any Pseudomonas group and subgroup, and should belong to a novel species within the genus Pseudomonas . This assertion is also supported by the results of genome average nucleotide identity analysis. The major fatty acids are C16 : 0, C18 : 1  ω7c and/or C18 : 1  ω6c, C16 : 1  ω7c and/or C16 : 1  ω6c. Polar lipids include phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, aminolipid and seven uncharacterized phospholipids. The predominant respiratory quinone is Q-9. The DNA G+C content is 59.45–59.50 mol%. Based on these data, we propose that the two novel strains should be assigned as a novel species within the genus Pseudomonas . We propose that the novel strains be named Pseudomonas quercus sp. nov. The type strain is hsmgli-8T (=CFCC 15739T=LMG 31544T).

Strains of Gram-negative anaerobic rods were isolated from chinchilla (Chinchilla lanigera) faeces, and three strains, ST161T, ST33 and ST37T, were investigated taxonomically. Based on phylogenetic analyses and specific phenotypic characteristics, the three strains were allocated to the genus Bacteroides . Phylogenetic analyses of their 16S rRNA gene sequences revealed that strain ST161T formed a distinct line of descent, with highest sequence similarity to strain ST33 (98.7 %) and Bacteroides oleiciplenus JCM 16102T (97.7 %). High levels of DNA–DNA relatedness (79–89 %) were found between strains ST161T and ST33, but low levels were found between strain ST161T and B. oleiciplenus JCM 16102T (33–37 %) and between strain ST33 and B. oleiciplenus JCM 16102T (33–37 %). These data clearly indicated that strains ST161T and ST33 represent a single novel species. 16S rRNA gene sequence analyses showed that strain ST37T also formed a distinct line of descent, with highest sequence similarity to Bacteroides acidifaciens JCM 10556T (96.5 %) and Bacteroides caccae JCM 9498T (95.6 %). Analysis of hsp60 gene sequences also supported these relationships. Based on phenotypic and phylogenetic characteristics, two novel species, Bacteroides stercorirosoris sp. nov. and Bacteroides faecichinchillae sp. nov., are thus proposed. The type strains of B. stercorirosoris and B. faecichinchillae are ST161T ( = JCM 17103T = CCUG 60872T) and ST37T ( = JCM 17102T = CCUG 60873T), respectively. The DNA G+C contents of strains ST161T and ST37T were 45.7 and 41.0 mol%, respectively.

Two Gram-stain-negative, aerobic, non-motile bacteria, designated KMS-5T and CYK-10T, were isolated from freshwater environments. 16S rRNA gene sequence similarity results indicated that these two novel strains belong to the family Rhodobacteraceae . Strain KMS-5T is closely related to species within the genus Tabrizicola (96.1–96.8 % sequence similarity) and Cypionkella (96.5–97.0 %). Strain CYK-10T is closest to Rhodobacter thermarum YIM 73036T with 96.6 % sequence similarity. Phylogenetic analyses based on 16S rRNA gene sequences and an up-to-date bacterial core gene set showed that strain KMS-5T is affiliated with species in the genus Tabrizicola and strain CYK-10T is placed in a distinct clade with Rhodobacter blasticus ATCC 33485T, Rhodobacter thermarum YIM 73036T and Rhodobacter flagellatus SYSU G03088T. These two strains shared common chemotaxonomic features comprising Q-10 as the major quinone, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine as the principal polar lipids, and C18 : 1  ω7c as the main fatty acid. The average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization values between these two novel isolates and their closest relatives were below the cut-off values of 95–96, 90 and 70 %, respectively, used for species demarcation. The obtained polyphasic taxonomic data suggested that strain KMS-5T represents a novel species within the genus Tabrizicola , for which the name Tabrizicola oligotrophica sp. nov. is proposed with KMS-5T (=BCRC 81196T=LMG 31337T) as the type strain, and strain CYK-10T should represent a novel species of the genus Rhodobacter , for which the name Rhodobacter tardus sp. nov. is proposed with CYK-10T (=BCRC 81191T=LMG 31336T) as the type strain.

A novel Gram-negative, aerobic, non-motile, ovoid to rod-shaped bacterium, designated NBD-18T, was isolated from a freshwater river in Taiwan. Optimal growth occurred at 30 °C, at pH 6 and in the absence of NaCl. The predominant fatty acids of strain NBD-18T were C16 : 0, summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c), C17 : 0 cyclo and summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidyldimethylethanolamine. The major polyamine was putrescine. The major isoprenoid quinone was Q-8. The genomic DNA G+C content of strain NBD-18T was 50.9 %. Strain NBD-18T was most closely related to Orrella dioscoreae LMG 29303T and Algicoccus marinus HZ20T at a 16S rRNA gene sequence similarity of 97.7 %. 16S rRNA gene sequence similarity between O. dioscoreae LMG 29303T and A. marinus HZ20T was 97.7 %. Phylogenetic analyses based on 16S rRNA gene sequences and an up-to-date bacterial core gene set indicated that strain NBD-18T, O. dioscoreae LMG 29303T and A. marinus HZ20T are affiliated with the same genus. Digital DNA–DNA hybridization, average nucleotide identity and average amino acid identity values among these three strains supported that they belong to the same genus and that strain NBD-18T represents a novel species. Thus, A. marinus HZ20T should be reclassified as Orrella marina comb. nov. based on the rules for priority of publication and validation. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain NBD-18T represents a novel species in the genus Orrella , for which the name Orrella amnicola sp. nov. is proposed. The type strain is NBD-18T (=BCRC 81197T=LMG 31338T).

Strains LMG 27428T and LMG 27427 were isolated from the caecal content of a chicken and produced butyric, lactic and formic acids as major metabolic end products. The genomic DNA G+C contents of strains LMG 27428T and LMG 27427 were 40.4 and 38.8 mol%. On the basis of 16S rRNA gene sequence similarity, both strains were most closely related to the generically misclassified Streptococcus pleomorphus ATCC 29734T. Strain LMG 27428T could be distinguished from S. pleomorphus ATCC 29734T based on production of more lactic acid and less formic acid in M2GSC medium, a higher DNA G+C content and the absence of activities of acid phosphatase and leucine, arginine, leucyl glycine, pyroglutamic acid, glycine and histidine arylamidases, while strain LMG 27428 was biochemically indistinguishable from S. pleomorphus ATCC 29734T. The novel genus Faecalicoccus gen. nov. within the family Erysipelotrichaceae is proposed to accommodate strains LMG 27428T and LMG 27427. Strain LMG 27428T ( = DSM 26963T) is the type strain of Faecalicoccus acidiformans sp. nov., and strain LMG 27427 ( = DSM 26962) is a strain of Faecalicoccus pleomorphus comb. nov. (type strain LMG 17756T = ATCC 29734T = DSM 20574T). Furthermore, the nearest phylogenetic neighbours of the genus Faecalicoccus are the generically misclassified Eubacterium cylindroides DSM 3983T (94.4 % 16S rRNA gene sequence similarity to strain LMG 27428T) and Eubacterium biforme DSM 3989T (92.7 % 16S rRNA gene sequence similarity to strain LMG 27428T). We present genotypic and phenotypic data that allow the differentiation of each of these taxa and propose to reclassify these generically misnamed species of the genus Eubacterium formally as Faecalitalea cylindroides gen. nov., comb. nov. and Holdemanella biformis gen. nov., comb. nov., respectively. The type strain of Faecalitalea cylindroides is DSM 3983T = ATCC 27803T = JCM 10261T and that of Holdemanella biformis is DSM 3989T = ATCC 27806T = CCUG 28091T.

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).
