The 16S Rrna Gene

A beige-pigmented, oxidase-positive bacterial isolate, Wesi-4T, isolated from charcoal in 2012, was examined in detail by applying a polyphasic taxonomic approach. Cells of the isolates were rod shaped and Gram-stain negative. Examination of the 16S rRNA gene sequence of the isolate revealed highest sequence similarities to the type strains of Pseudomonas matsuisoli and Pseudomonas nosocomialis (both 97.3 %). Phylogenetic analyses on the basis of the 16S rRNA gene sequences indicated a separate position of Wesi-4T, which was confirmed by multilocus sequence analyses (MLSA) based on the three loci gyrB, rpoB and rpoD and a core genome-based phylogenetic tree. Genome sequence based comparison of Wesi-4T and the type strains of P. matsuisoli and P. nosocomialis yielded average nucleotide identity values <95 % and in silico DNA-DNA hybridization values <70 %, respectively. The polyamine pattern contains the major amines putrescine, cadaverine and spermidine. The quinone system contains predominantly ubiquinone Q-9 and in the polar lipid profile diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine are the major lipids. The fatty acid contains predominantly C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 8 (C18 : 1ω7c and/or C18 : 1 ω6c). In addition, physiological and biochemical tests revealed a clear phenotypic difference from P. matsuisoli . These cumulative data indicate that the isolate represents a novel species of the genus Pseudomonas for which the name Pseudomonas carbonaria sp. nov. is proposed with Wesi-4T (=DSM 110367T=CIP 111764T=CCM 9017T) as the type strain.

A Gram-staining-negative, non-flagellated, non-gliding and pleomorphic bacterial strain, designated DPG-25T, was isolated from seawater in a seaweed farm in the South Sea in Korea and its taxonomic position was investigated by using a polyphasic approach. Strain DPG-25T grew optimally at 25 °C, at pH 7.0–7.5 and in the presence of 2 % (w/v) NaCl. Flexirubin-type pigments were not produced. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DPG-25T formed a cluster with the type strains of Actibacter sediminis , Aestuariicola saemankumensis and Lutimonas vermicola . Strain DPG-25T exhibited 16S rRNA gene sequence similarity values of 95.3, 93.1 and 93.6 % to the type strains of Actibacter sediminis , Aestuariicola saemankumensis and L. vermicola , respectively. Strain DPG-25T contained MK-6 as the predominant menaquinone and iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain DPG-25T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content was 39.9 mol%. Differential phenotypic properties and the phylogenetic distinctiveness of strain DPG-25T demonstrated that this strain is distinguishable from Actibacter sediminis , Aestuariicola saemankumensis and L. vermicola . On the basis of the data presented here, strain DPG-25T represents a novel species in a novel genus of the family Flavobacteriaceae , for which the name Namhaeicola litoreus gen. nov., sp. nov. is proposed. The type strain of Namhaeicola litoreus is DPG-25T ( = KCTC 23702T  = CCUG 61485T).

Chakrabartia godavariana PRB40T was compared with Aestuariisphingobium litorale SYSU M10002T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of C. godavariana PRB40T had high similarity (99.8 %) to that of A. litorale SYSU M10002T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Chakrabartia . A draft genomic comparison between the two strains revealed an average nucleotide identity of 97.3 % and a digital DNA–DNA hybridization estimate of 79.5±2.9 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking differences in metabolic, physiological or chemotaxonomic features. Therefore, we propose that Aestuariisphingobium litorale is a later heterotypic synonym of Chakrabartia godavariana .

The 16S Rrna Gene

A novel actinobacterium, strain BC637T, was isolated from a biodeteriogenic biofilm sample collected in 2009 in the Saint Callixstus Roman catacomb. The strain was found to belong to the genus Kribbella by analysis of the 16S rRNA gene. Phylogenetic analysis using the 16S rRNA gene and the gyrB, rpoB, relA, recA and atpD concatenated gene sequences showed that strain BC637T was most closely related to the type strains of Kribbella lupini and Kribbella endophytica . DNA–DNA hybridization experiments confirmed that strain BC637T is a genomic species that is distinct from its closest phylogenetic relatives, K. endophytica DSM 23718T (63 % DNA relatedness) and K. lupini LU14T (63 % DNA relatedness). Physiological comparisons showed that strain BC637T is phenotypically distinct from the type strains of K. endophytica and K. lupini . Thus, strain BC637T represents the type strain of a novel species, for which the name Kribella italica sp. nov. is proposed ( = DSM 28967T = NRRL B-59155T).

The 16S Rrna Gene

Bacterial strains YM16-303T and YM16-304T were isolated from a sample of seashore sand using a medium with an artificial seawater base. Both isolates grew slowly on marine agar, and were found to be Gram-reaction-positive, aerobic, non-motile and rod-shaped. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glycine, alanine and hydroxyglutamic acid, and the acyl type of the muramic acid was glycolyl. The predominant menaquinone was MK-9(H8). The 16S rRNA gene sequences of strains YM16-303T and YM16-304T were most similar to that of Ilumatobacter fluminis YM22-133T, and phylogenetic analyses also indicated that they belong to the genus Ilumatobacter . Ilumatobacter fluminis YM22-133T and strains YM16-303T and YM16-304T should be classified as distinct species in the genus Ilumatobacter , however, since the 16S rRNA gene sequence similarity between them was low and the major cellular fatty acids and some physiological properties were different. Moreover, average nucleotide identity and maximal unique exact matches index values also supported the conclusion that they represent different species. On the basis of the above analyses, two novel species, Ilumatobacter nonamiense sp. nov. (type strain YM16-303T = NBRC 109120T = KCTC 29139T) and Ilumatobacter coccineum sp. nov. (type strain YM16-304T = NBRC 103263T = KCTC 29153T), are proposed. The order Acidimicrobiales , which contains the genus Ilumatobacter , currently includes six genera and only six species, and they are phylogenetically very far from each other. Phylogenetic analyses revealed that strains YM16-303T and YM16-304T clustered with closely related uncultured actinobacteria but not Ilumatobacter fluminis YM22-133T, suggesting that many uncultured bacteria related to these isolates exist in the environment. This is the first report on interspecies relationships in the order Acidimicrobiales .

Cellulomonas algicola KZ-21T was compared with Cellulomonas aurantiaca THG-SMD2.3T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of Cellulomonas algicola KZ-21T shared complete similarity (100.0 %) with that of Cellulomonas aurantiaca THG-SMD2.3T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Cellulomonas . Genome comparison between the two strains revealed an average nucleotide identity of 99.2 % and a digital DNA–DNA hybridization estimate of 93.7±1.8 %, strongly indicating that the two strains belong to a single species. In addition, neither strain displayed any striking differences in metabolic, physiological or chemotaxonomic features. Therefore, we propose Cellulomonas aurantiaca as a later heterotypic synonym of Cellulomonas algicola .

Sequence Similarities

A Gram-stain-negative, aerobic, non-flagellated, non-spore-forming, motile (by gliding) bacterial strain, designated M-M6T, was isolated from marine sand of Geoje island, Korea. Strain M-M6T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain M-M6T fell within the clade comprising Cellulophaga species, forming a coherent cluster with Cellulophaga lytica ATCC 23178T and Cellulophaga fucicola NN015860T, with which it shared 16S rRNA gene sequence similarities of 98.1 and 98.2 %, respectively. Sequence similarities between strain M-M6T and the type strains of other recognized Cellulophaga species were in the range 92.4–93.8 %. Strain M-M6T contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH, and C16 : 1ω7c and/or iso-C15 : 0 2-OH as the major fatty acids. The major polar lipids detected in strain M-M6T and the type strains of C. lytica and C. fucicola were two unidentified lipids, one unidentified aminolipid and one unidentified aminophospholipid. The DNA G+C content of strain M-M6T was 35.4 mol%. Levels of DNA–DNA relatedness between strain M-M6T and C. lytica JCM 8516T and C. fucicola JCM 21778T were 33 and 35 %, respectively. Differential phenotypic properties and phylogenetic and genetic distinctiveness distinguished strain M-M6T from all recognized Cellulophaga species. On the basis of the data presented, strain M-M6T is considered to represent a novel species of the genus Cellulophaga , for which the name Cellulophaga geojensis sp. nov. is proposed. The type strain is M-M6T ( = KCTC 23498T = CCUG 60801T).

A novel actinobacterium, strain BC640T, was isolated from a biofilm sample collected in 2009 in the Saint Callistus Roman catacombs. Analysis of the 16S rRNA gene sequence showed that the strain belonged to the genus Kribbella . Phylogenetic analysis using the 16S rRNA gene and concatenated gyrB, rpoB, relA, recA and atpD gene sequences showed that strain BC640T was most closely related to the type strains of Kribbella yunnanensis and Kribbella sandramycini . Based on gyrB genetic distance analysis, strain BC640T was shown to be distinct from all Kribbella type strains. DNA–DNA hybridization experiments confirmed that strain BC640T represents a genomic species distinct from its closest phylogenetic relatives, K. yunnanensis DSM 15499T (53.5±7.8 % DNA relatedness) and K. sandramycini DSM 15626T (33.5±5.0 %). Physiological comparisons further showed that strain BC640T is phenotypically distinct from the type strains of K. yunnanensis and K. sandramycini . Strain BC640T ( = DSM 26744T = NRRL B-24917T) is thus presented as the type strain of a novel species, for which the name Kribbella albertanoniae sp. nov. is proposed.

Sequence Similarities

Five beige bacterial strains (176/10T, 178/10, 182/10, 185/7 and 193/8) were isolated from white storks in Poland and found to share identical 16S rRNA gene sequences; they were also investigated in a polyphasic taxonomic study. The cells of all isolates were rod-shaped and Gram-stain-negative. A comparison of the 16S rRNA gene sequences of these organisms with the sequences of the type strains of the most closely related species of the genus Psychrobacter showed highest sequence similarities to the type strains of Psychrobacter pulmonis and Psychrobacter faecalis (both 97.1 %). The 16S rRNA gene sequence similarities to all other species of the genus Psychrobacter were below 96.3 %. All five isolates showed an identical profile of physiological reactions and almost identical fatty acid profiles consisting of mainly C18 : 1ω9c, but also C12 : 0 3-OH as a characteristic hydroxylated fatty acid. A quinone system with mainly ubiquinone Q-8 was detected and the polar lipid profile of the type strain, 176/10T, was mainly composed of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine and diphosphatidylglycerol, plus some hitherto uncharacterized phospholipids and one aminolipid. The major polyamines were spermidine and putrescine. DNA–DNA hybridizations between 176/10T and the type strains of P. pulmonis and P. faecialis resulted in relatedness values below 70 %. These results indicate that the strains represent a novel species, for which the name Psychrobacter ciconiae sp. nov. (type strain 176/10T = CIP 110777T = LMG 28175T = CCM 8519T) is proposed.

A Gram-reaction-negative, non-spore-forming, gliding, non-translucent, colourless or yellow, aerobic and elevated-colony-forming strain, designated E403T, was isolated from the Bashi Channel and subjected to a polyphasic taxonomic study. Strain E403T could grow in the presence of 0.3–8 % (w/v) NaCl, at 16–43 °C and at pH 6–9, and grew optimally at 28 °C, pH 8, in natural seawater medium. The respiratory quinones were MK-6 and MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), iso-C15 : 0 3-OH and C16 : 0. The DNA G+C content of strain E403T was 37.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences of members of the family Flavobacteriaceae showed that strain E403T formed a distinct evolutionary lineage within the stable cluster containing type strains Zhouia amylolytica HN-171T (92.2 % similarity) and Joostella marina En5T (92.4 % similarity). In addition to the large 16S rRNA gene sequence differences, E403T can also be distinguished from the reference type strains J. marina En5T and Sinomicrobium oceani SCSIO 03483T by several phenotypic characteristics and chemotaxonomic properties. On the basis of phenotypic, chemotaxonomic and phylogenetic properties, strain E403T is suggested to represent a novel species of a new genus in the family Flavobacteriaceae , for which the name Pustulibacterium marinum gen. nov., sp. nov. is proposed. The type strain is E403T ( = CCTCC AB2012862T = CGMCC 1.12333T = KCTC 32192T).

Parvularcula flava was proposed as a novel member of genus Parvularcula in 2016. Some time earlier, Aquisalinus flavus has been proposed as a novel species of a novel genus named Aquisalinus . When comparing the 16S rRNA gene sequences of type strains P. flava NH6-79T and A. flavus D11M-2T, they showed 97.9 % sequence identity, much higher than the sequence identities 92.7–94.3 % between P. flava NH6-79T and type strains in the genus Parvularcula , indicating that the later proposed novel taxon Parvularcula flava need reclassification. The phylogenetic trees based on 16S rRNA gene sequences and genome sequences both showed that P. flava NH6-79T and A. flavus D11M-2T formed a separated branch away from strains in the genera Parvularcula , Marinicaulis and Amphiplicatus . The average amino acid identity and average nucleotide identity values of P. flava NH6-79T and A. flavus D11M-2T were 87.9 and 85.0 %, respectively, much higher than the values between P. flava NH6-79T and other closely related type strains (54.3 %–58.1 % and 68.6–70.4 %, respectively). P. flava NH6-79T and A. flavus D11M-2T also contained summed feature 8 (C18 : 1  ω6c and/or C18 : 1  ω7c) and C16 : 0 as major fatty acids, distinguishing them from other closely related taxa. Based on the results of the phylogenetic, comparative genomic and phenotypic analyses, Parvularcula flava should be reclassified as Aquisalinus luteolus nom. nov. and the description of genus Aquisalinus is emended.
