Sequence Similarities

A Gram-negative, rod-shaped bacterium was isolated from the skin of the medical leech Hirudo verbana and studied for its taxonomic allocation. 16S rRNA gene sequence similarities to other strains showed that the strain was closely related to species of the genus Kaistia . Kaistia geumhonensis was shown to be the most closely related species (96.8 %), followed by Kaistia soli (96.6 %) and Kaistia dalseonensis (96.2 %). All other species of the genus Kaistia showed 16S rRNA gene sequence similarities <96 %. Chemotaxonomic data for strain E94T (major ubiquinone: Q-10; major polar lipids: diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylserine, unknown phospholipids, aminolipids and aminophospholipids; and major fatty acids: C18 : 1ω7c, C19 : 0ω8c cylco, C16 : 0 and C18 : 0) supported the affiliation of the isolate to the genus Kaistia . Phenotypic differentiation of strain E94T from all species of the genus Kaistia was possible using different physiological characters. Strain E94T represents a novel species of the genus Kaistia , for which the name Kaistia hirudinis sp. nov. is proposed, with the type strain E94T ( = LMG 26925T = CIP 110381T = CCM 8401T).

Six Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile strains (FT9WT, FT25W, FT26WT, FT109WT, FT134W and CY42WT) were isolated from subtropical streams in China. Comparisons based on 16S rRNA gene sequences showed that the six strains shared similarities of less than 98.1 % with other species within the family Oxalobacteraceae and formed two separately distinct clades in phylogenetic trees. The 16S rRNA gene sequence similarities between strains FT9WT and FT25W, and between strains FT109WT and FT134W were both 99.7 %. The genome sizes of strains FT9WT, FT25W, FT26WT, FT109WT, FT134W and CY42WT were 6.45, 6.45, 6.54, 6.43, 6.52 and 6.74 Mbp with G+C contents of 64.0, 64.0, 63.8, 63.2, 63.2 and 62.5 %, respectively. The calculated pairwise average nucleotide (ANI) values among the six strains and other related species were less than 93.9 %, except that the values were 99.9 % between strains FT9WT and FT25W, 98.2 % between strains FT109WT and FT134W, and 95.0 and 95.1 % between strain FT26WT and strains FT9WT and FT25W, respectively. However, strain FT26WT shared 16S rRNA gene sequence similarities of only 98.3 and 98.2 % with FT9WT and FT25W, respectively. The respiratory quinone of the six strains was determined to be Q-8. The major fatty acids were C16 : 1 ω7c, C16 : 0 and C12 : 0. The predominant polar lipids included phosphatidylethanolamine and phosphatidylglycerol. Considering the phenotypic, biochemical, genotypic and ANI data, strains FT9WT and FT25W, and FT109WT and FT134W may belong to the same species, respectively. Although the pairwise ANI values between strain FT26WT and each of strains FT9WT and FT25W were located in the transition region of species demarcation, the dissimilarities among them indicated that strain FT26WT could represent an independent novel species. The reconstructed phylogenomic tree based on a concatenation of 92 core genes showed that the six strains clustered closely with Duganella sacchari Sac-22T and Duganella radicis KCTC 22382T, and supported that these six strains belong to the genus Duganella . The names Duganella albus sp. nov. (type strain FT9WT=GDMCC 1.1637T=KACC 21313T), Duganella aquatilis sp. nov. (type strain FT26WT=GDMCC 1.1641T=KACC 21315T), Duganella pernnla sp. nov. (type strain FT109WT=GDMCC 1.1688T=KACC 21480T) and Duganella levis sp. nov. (type strain CY42WT=GDMCC 1.1673T=KACC 21465T) are proposed.

Hirudo Verbana

A Gram-staining-negative, rod-shaped, non-spore-forming bacterium, designated strain E103T, was isolated from the skin of the medical leech Hirudo verbana. 16S rRNA gene sequence analysis showed that the isolate was closely related to species of the genus Castellaniella . Castellaniella ginsengisoli DCY36T was shown to be the most closely related (98.4 % 16S rRNA gene sequence similarity), followed by Castellaniella denitrificans NKNTAUT and Castellaniella daejeonensis MJ06T (both 97.8 %), then Castellaniella caeni Ho-11T (97.5 %). Chemotaxonomic data (major ubiquinone, Q-8; major polar lipids, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylserine; predominant polyamine, putrescine with a moderate amount of 2-hydroxyputrescine; and major fatty acids, C17 : 0 cyclo, C16 : 0 and summed feature 4 comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH) supported the affiliation of the isolate to the genus Castellaniella . DNA–DNA hybridization values with the type strains of all species of the genus Castellaniella were 23 % (reciprocal, 18 %) with C. ginsengisoli KCTC 22398T, 20 % (26 %) with C. daejeonensis KCTC 22454T, 11 % (58 %) with C. denitrificans DSM 11046T and 13 % (12 %) with C. caeni KCTC 12197T . Phenotypic differentiation of strain E103T from its closest neighbours was possible. Strain E103T therefore represents a novel species of the genus Castellaniella , for which the name Castellaniella hirudinis sp. nov. is proposed, with the type strain E103T ( = CCUG 62394T = LMG 26910T).

A Gram-negative, moderately halophilic and facultatively aerobic bacterium, designated strain GTF13T, was isolated from a sea tidal flat. Cells were curved rods and motile by a single polar flagellum showing catalase and oxidase activities. Growth was observed at 20–37 °C, pH 5.0–8.5 and 1.0–6.0 % (w/v) NaCl. Strain GTF13T contained C16:0, summed feature 3 (comprising C16 : 1  ω6c/C16 : 1  ω7c), summed feature 8 (comprising C18 : 1  ω6c/C18 : 1  ω7c) and C12 : 0 3-OH as major fatty acids and ubiquinone-9 and ubiquinone-8 as major quinones. Phosphatidylethanolamine and two unidentified phospholipids were detected as major polar lipids. The G+C content of the genomic DNA was 59.8 mol%. Strain GTF13T was most closely related to Simiduia agarivorans SA1T, Endozoicomonas montiporae CL-33T and Pseudomonas segetis FR1439T, belonging to different families or orders of the class Gammaproteobacteria , with less than 92.0 % 16S rRNA gene sequence similarities. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain GTF13T formed a phylogenetic lineage with the family Litoricolaceae , but the genome-based phylogenomic tree showed that strain GTF13T formed a distinct phylogenetic lineage within the order Oceanospirillales . The very low 16S rRNA gene sequence similarities and distinct phylogenetic relationships, together with distinct phenotypic and chemotaxonomic properties, served to differentiate strain GTF13T from phylogenetically closely related families. Here, strain GTF13T is proposed as a novel genus and species, for which the name Aestuariirhabdus litorea gen. nov., sp. nov. is proposed, within a new family Aestuariirhabdaceae fam. nov. of the order Oceanospirillales . The type strain is GTF13T (=KACC 19788T=JCM 32043T).

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.

Murray Cod

A Gram-stain-negative, strictly aerobic, motile, rod-shaped bacterium with monopolar flagella, designated as MC042T, was isolated from the profound head ulcers of farmed Murray cod sampled from Zhejiang Province, China. Analysis of its 16S rRNA gene sequence and multilocus sequence analysis phylogeny showed that strain MC042T belonged to the genus Pseudomonas , showing the highest 16S rRNA gene sequence similarity to Pseudomonas juntendi BML3T (98.9 %), and less than 98.8 % similarity to other Pseudomonas species with validly published names. Whole-genome sequencing and phylogenetic reconstruction based on a core set of 1563 Pseudomonas genes further indicated that strain MC042T was most closely related to the clade formed by Pseudomonas protegens CHA0T and Pseudomonas saponiphila DSM 975T and distantly related to any of the validly published species of the genus Pseudomonas . Furthermore, strain MC042T could be distinguished from its closely related species of the genus Pseudomonas by its ability to assimilate maltose, d-xylose and melibiose, but not d-mannitol. The principal fatty acids were C16 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) and summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c). The respiratory quinone was Q-9. Polar lipids of strain MC042T comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, unidentified glycolipids, an unidentified lipid, an unknown glycolipid and aminolipid. Based on its phenotypic, chemotaxonomic and phylogenetic features, strain MC042T is considered to represent a novel species, for which the name Pseudomonas piscis sp. nov. is proposed. The type strain is MC042T (=KCTC 72033T=MCCC 1K03575T).

A novel actinomycete, designated strain NEAU-TCZ24T, was isolated from soil and characterized using a polyphasic approach. The results of phylogenetic analysis based on the 16S rRNA gene sequence indicated that the organism should be assigned to the genus Cellulomonas and formed a stable clade with its closest relatives Cellulomonas terrae JCM 14899T (98.4 % 16S rRNA gene sequence similarity), Cellulomonas xylanilytica JCM 14281T (97.9 %) and Cellulomonas humilata JCM 11945T (97.7 %). The major menaquinones were identified as MK-9(H4) and MK-8(H4). The phospholipid profile was found to contain diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositolmannoside, a ninhydrin-positiveglycolipid, an unidentified phosphoglycolipid, an unidentified phospholipid and an unidentified lipid. The major fatty acids were identified as anteiso-C15 : 0, C18 : 1ω9c, C16 : 0 and anteiso-C17 : 0. Moreover, morphological and chemotaxonomic properties of NEAU-TCZ24T also confirmed the affiliation of the isolate to the genus Cellulomonas . However, multilocus sequence analysis based on five other house-keeping genes (gyrB, rpoB, recA, relA and atpD), DNA–DNA relatedness, physiological and biochemical data indicated that NEAU-TCZ24T could be distinguished from its closest relatives. Therefore, it is proposed that NEAU-TCZ24T represents a novel species of the genus Cellulomonas , for which the name Cellulomonas rhizosphaerae sp. nov. is proposed. The type strain is NEAU-TCZ24T (=CCTCC AA 2018042T=JCM 32383T).

A Gram-negative bacterium, designated TF5-37.2-LB10T, was isolated from subsurface water of the Toarcian geological layer of Tournemire, France. Cells were non-motile straight rods that formed cream to light pink colonies on 10-fold diluted LB agar. Strain TF5-37.2-LB10T contained menaquinone 7 and its major fatty acids were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C17 : 0 3-OH and iso-C17 : 1ω9c. The G+C content of the genomic DNA was 46 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain TF5-37.2-LB10T within the genus Pedobacter , family Sphingobacteriaceae . Pedobacter composti TR6-06T and Pedobacter oryzae DSM 19973T were the closest phylogenetic relatives (93.5 and 93.3 % 16S rRNA gene sequence similarity, respectively). On the basis of 16S rRNA gene sequence comparison and physiological and biochemical characteristics, strain TF5-37.2-LB10T represents a novel species of the genus Pedobacter , for which the name Pedobacter tournemirensis sp. nov. is proposed. The type strain is TF5-37.2-LB10T ( = DSM 23085T = CIP 110085T = MOLA 820T).

A novel type of freshwater bacterium was isolated from the prealpine mesotrophic Starnberger See (Bavaria, southern Germany). Cells of strain 382T were Gram-negative and rod-shaped, motile and creamy-white. The isolate was strictly aerobic, catalase- and oxidase-positive, and grew at pH values of 6–9 (optimum, pH 7) and temperatures of 10–37 °C (optimum, 28 °C). The genomic G+C content of strain 382T was 64.1 mol%. Based on 16S rRNA gene sequence analyses, strain 382T belongs to the family Sphingomonadaceae and clusters within the genus Sphingomonas . Sphingomonas histidinilytica UM 2T and Sphingomonas wittichii DSM 6014T were the closest relatives, as indicated by the highest 16S rRNA gene sequence similarities (97.1 % and 96.8 %, respectively). Sphingomonas paucimobilis DSM 1098T (the type species of the genus Sphingomonas ) exhibited 95.3 % sequence similarity. This affiliation of strain 382T to the genus Sphingomonas is confirmed by the presence of Q-10 as the major respiratory quinone, two sphingoglycolipids, C14 : 0 2-OH as the major 2-hydroxy fatty acid and sym-homospermidine as the major polyamine. The main cellular fatty acids of strain 382T were C18 : 1ω7c (39 %), C16 : 1ω7c (21 %), C16 : 0 (10 %) and C14 : 0 2-OH (10 %). Based on the phylogenetic distance from other species of the genus Sphingomonas and its unusually high C16 : 1ω7c content, strain 382T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas starnbergensis is proposed. The type strain is 382T ( = DSM 25077T  = LMG 26763T).

Four Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile strains (Y26, Y57T, ZJ14WT and RP18W) were isolated from mariculture fishponds in PR China. Comparisons based on 16S rRNA gene sequences showed that strains Y26 and Y57T share 16S rRNA gene sequence similarities in the range of 95.1−98.5 % with species of the genus Bowmanella , and strains ZJ14WT and RP18W share 16S rRNA gene sequence similarities in the range of 96.7 −98.8 % with species of the genus Amphritea , respectively. The genome sizes of strains Y26, Y57T, ZJ14WT and RP18W were about 4.85, 5.40, 4.70 and 4.70 Mbp with 49.5, 51.7, 51.2 and 51.3 mol% G+C content, respectively. The calculated pairwise OrthoANIu values among strains Y26, Y57T and species of the genus Bowmanella were in the range of 72.6−83.1 %, but the value between strains Y26 and Y57T was 96.2 %. The pairwise OrthoANIu values among strains ZJ14WT, RP18W and other species of the genus Amphritea were all less than 93.9 %, but the value between strains ZJ14WT and RP18W was 99.3 %. Q-8 was the major respiratory quinone of strains Y26, Y57T, ZJ14WT and RP18W, and the major fatty acids of these strains were all C16 : 1 ω7c, C16 : 0 and C18 : 1 ω7c. The predominant polar lipids of strains Y26 and Y57T included phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylinositol, but strains ZJ14WT and RP18W only contained phosphatidylethanolamine and phosphatidylglycerol. Combining phenotypic, biochemical and genotypic characteristics, strains Y26 and Y57T should belong to the same species and represent a novel member of the genus Bowmanella , and strains ZJ14WT and RP18W should belong to the same species and represent a novel member of the genus Amphritea , for which the names Bowmanella yangjiangensis sp. nov. (type strain Y57T=GDMCC 1.2180T=KCTC 82439T) and Amphritea pacifica sp. nov. (type strain ZJ14WT=GDMCC 1.2203T=KCTC 82438T) are proposed.

An obligately anaerobic, non-motile, Gram-negative and rod-shaped strain (AGMB03916T) was isolated from faeces of a 2-week-old piglet raised at the National Institute of Animal Science in Wanju, Republic of Korea. Growth of strain AGMB03916T occurred at 30–45 °C (optimum, 37 °C), at pH 6–9 (optimum, pH 8) and in the presence of 0.5–1.0 % (w/v) NaCl. Based on the results of 16S rRNA gene sequence analyses, strain AGMB03916T was closely related to two validly published species of the genus Phocaeicola , Phocaeicola plebeius and Phocaeicola coprocola . The 16S rRNA gene sequence similarity of strain AGMB03916T compared to P. plebeius M12T (=KCTC 5793T) and P. coprocola M16T (=KCTC 5443T) were 96.3 and 95.0 %, respectively. The genomic DNA G+C content of strain AGMB03916T was 46.4 mol%. The average nucleotide identity values between strain AGMB03916T and the reference strains were 74.9–78.5 %. Cells were able to utilize d-glucose, lactose, sucrose, maltose, salicin, aesculin hydrolysis, cellobiose and raffinose. The major end product of metabolism was acetate. The major cellular fatty acids (>10 %) of the isolate were iso-C15 : 0, anteiso-C15 : 0, C16 : 0, C16 : 0 3-OH and summed feature 11 (iso-C17 : 0 3-OH and/or C18 : 2 DMA). On the basis of the genotypic, biochemical, chemotaxonomic, phenotypic and phylogenetic data, strain AGMB03916T represents a novel species of the genus Phocaeicola , for which the name Phocaeicola faecicola sp. nov. is proposed. The type strain is AGMB03916T (=KCTC 25014T=GDMCC 1.2574T).
