The 16S Rrna Gene

A novel facultatively anaerobic strain, designated GPTSA 19T, was isolated from a warm spring and characterized using a polyphasic approach. The strain behaved as Gram-negative in the Gram staining procedure but showed a Gram-positive reaction in the aminopeptidase test. The novel strain was a mesophilic rod with ellipsoidal endospores. On the basis of 16S rRNA gene sequence analysis, the strain showed closest similarity (96.0 %) with Paenibacillus motobuensis MC10T. The gene sequence similarity of the novel strain with other species of the genus Paenibacillus was <95.8 %. The novel strain also had PAEN 515F and 682F signature sequence stretches in the 16S rRNA gene that are usually found in most species of the genus Paenibacillus. The strain possessed anteiso-C15 : 0 as the major fatty acid and MK-7 as the predominant menaquinone. Polar lipids included diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), six unknown phospholipids (PLs), one aminophospholipid (PN), three glycolipids (GLs), two aminolipids (ALs), one aminophosphoglycolipid (APGL) and three unknown lipids (ULs). The polar lipid profile of the novel strain, especially as regards ALs, GLs and PLs, distinguished it from the recognized type species of the genus Paenibacillus, Paenibacillus polymyxa, as well as from its closest relative P. motobuensis. Based on phenotypic and chemotaxonomic characteristics and analysis of the 16S rRNA gene sequence, the new strain merits the rank of a novel genus for which the name Fontibacillus gen. nov. is proposed. The type species of the new genus is Fontibacillus aquaticus gen. nov., sp. nov. with the type strain GPTSA 19T (=MTCC 7155T=DSM 17643T).

The 16S Rrna Gene

A novel Gram-staining-negative gammaproteobacterium, designated IITR-13T, was isolated from a pesticide-contaminated soil and characterized using a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, the strain showed the closest similarity (98.7 %) to Rheinheimera tangshanensis JA3-B52T followed by Rheinheimera texasensis A62-14BT (97.7 %) and Rheinheimera soli BD-d46T (97.3 %). The 16S rRNA gene sequence similarity of the novel strain to other members of the genus Rheinheimera was < 97.3 %. However, DNA–DNA hybridization between strain IITR-13T and the type strains of R. tangshanensis, R. texasensis and R. soli was 47.5 ± 0.6, 42.4 ± 0.4 and 39.8 ± 0.3 %, respectively; these values are less than 70 %, a threshold value for delineation of a novel species. The strain had C12 : 0 3-OH, C16 : 0, C17 : 1ω8c, summed feature 3 (C16 : 1ω6c/C16 : 1ω7c) and C18 : 1ω6c as the major fatty acids. The major isoprenoid quinones detected for strain IITR-13T were ubiquinone Q-8 and menaquinone MK-7.The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and seven unknown phospholipids. Based on phenotypic and chemotaxonomic characteristics and analysis of the 16S rRNA gene sequence, the novel strain should be assigned to a novel species, for which the name Rheinheimera mesophila sp. nov. is proposed, with the type strain IITR-13T ( = MTCC 12064T = DSM 29723T). Also, we report the draft genome sequence of Rheinheimera mesophila IITR-13T; the draft genome sequence includes 3 749 903 bases and comprises 3449 predicted coding sequences, with a G+C content of 47.8 %. It consists of 102 contigs (>1000 bp).

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.

Moderately Halophilic Bacterium

A moderately halophilic bacterium, strain YIM 70202T, was isolated from a desert soil sample collected from Egypt and was subjected to a taxonomic investigation. In a phylogenetic dendrogram based on 16S rRNA gene sequence analysis, strain YIM 70202T was affiliated to the Salinicoccus clade, showing 94.5–96.8 % 16S rRNA gene sequence similarity to the recognized species of the genus Salinicoccus, in which Salinicoccus roseus CCM 3516T was the nearest neighbour. The DNA–DNA relatedness value of the novel isolate with S. roseus CCM 3516T was 12.7 %. The novel isolate grew at temperatures between 4 and 45 °C and at pH values ranging from 7.0 to 11.0, with an optimum of 30 °C and pH 8.0–9.0, respectively. Strain YIM 70202T grew optimally in the presence of 10 % NaCl (w/v) and growth was observed at NaCl concentrations in the range 1–25 % (w/v). Chemotaxonomic data revealed that strain YIM 70202T contained MK-6 as the predominant respiratory quinone, possessed l-Lys–Gly5 as the cell-wall peptidoglycan, had phosphatidylglycerol, diphosphatidylglycerol and an unknown glycolipid as the polar lipids and contained i-C15 : 0 and ai-C15 : 0 as the predominant fatty acids. The DNA G+C content was 49.7 mol%. The biochemical and chemotaxonomic properties demonstrate that strain YIM 70202T represents a novel species of the genus Salinicoccus. The name Salinicoccus luteus sp. nov. is proposed with strain YIM 70202T (=CGMCC 1.6511T=KCTC 3941T) as the type strain.

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 marine bacterium, strain KMD 001T, was isolated from the starfish Asterias amurensis, which inhabits the East Sea of Korea. Strain KMD 001T was aerobic, light-yellow pigmented and Gram-stain-negative. Analyses of the 16S rRNA gene sequence revealed that strain KMD 001T represents a novel lineage within the class Gammaproteobacteria. Strain KMD 001T is closely related to the genera Endozoicomonas and Zooshikella, which belong to the family Hahellaceae and to the order Oceanospirillales. The 16S rRNA gene sequence of strain KMD 001T shows similarities of approximately 91.8–94.6 % with the above-mentioned genera. The DNA G+C content of KMD 001T is 47.6 mol%. It contains Q-9 as the major isoprenoid quinone. The predominant fatty acids were determined to be anteiso-C15 : 0, iso-C15 : 0, iso-C14 : 0 and iso-C16 : 0. Strain KMD 001T should be assigned to a novel bacterial genus within the class Gammaproteobacteria based on its phylogenetic, chemotaxonomic and phenotypic characteristics. The name Kistimonas asteriae gen. nov., sp. nov. is proposed. The type strain is KMD 001T (=KCCM 90076T =JCM 15607T).

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).

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).
