The 16S Rrna Gene

Strain DYT, which was isolated from garden soil in Japan, was subjected to a polyphasic taxonomic study. Sequence analysis of the 16S rRNA gene and the GyrB protein revealed that the closest relative of strain DYT was [Flavobacterium] ferrugineum Sickles and Shaw 1934, with 94.8 and 90.1 % similarity, respectively. The two strains had similar chemotaxonomic characteristics, with menaquinone 7 as the major quinone system, 47.2–48.9 mol% DNA G+C content and 15 : 0 iso, 15 : 1 iso, 17 : 0 iso 3-OH and summed feature 3 as the major fatty acids. Based on genotypic and phenotypic characteristics, [Flavobacterium] ferrugineum IAM 15098T could be clearly differentiated from other members of the genus Flavobacterium. Strain DYT and [Flavobacterium] ferrugineum IAM 15098T could be easily distinguished from neighbouring taxa by morphological features (non-motile, non-gliding and non-filamentous single cells). Therefore, it is proposed that [Flavobacterium] ferrugineum IAM 15098T and strain DYT represent two separate species of a new genus, Terrimonas gen. nov., with the names Terrimonas ferruginea comb. nov. (type species; type strain IAM 15098T=ATCC 13524T) and Terrimonas lutea sp. nov. (type strain DYT=IAM 15284T=CCTCC AB205006T), respectively.

In the course of phylogenetic analyses of the taxa within the suborder Pseudonocardineae, it was observed that Saccharothrix tangerinus MK27-91F2T was misplaced in the genus Saccharothrix. After a detailed examination of nucleotide signatures in the 16S rRNA gene sequence along with the morphological and chemotaxonomic characteristics of this strain, which are different from those of all species of Saccharothrix as well as the other genera within the suborder, it was concluded that this strain represents a new genus, for which the name Umezawaea gen. nov. is proposed. Pseudosporangia are produced on the aerial mycelium, the whole-cell sugar pattern consists of galactose, mannose and ribose, phosphatidylethanolamine, phosphatidylinositol and lyso-phosphatidylethanolamine are the predominant phospholipids and MK-9(H4) is the predominant menaquinone. The type species of the proposed new genus is Umezawaea tangerina gen. nov., comb. nov., with the type strain MK27-91F2T (=NRRL B-24463T =DSM 44720T =FERM P-16053T =JCM 10302T =NBRC 16184T).

The 16S Rrna Gene

A novel thermophilic, strictly anaerobic, chemo-organotrophic bacterium, designated MCT, was isolated from a geothermally heated sediment of a marine hydrothermal system at Palaeochory Bay, Milos, Greece. Cells of strain MCT were rods of variable length (4–12 μm) and width (0.2–0.3 μm), occurring as single cells or forming large aggregates that were visible as flocs. Strain MCT grew optimally at pH 7.0 and 60 °C and with 3 % (w/v) NaCl. Strain MCT grew chemo-organoheterotrophically and fermented peptides and di- and polysaccharides in the presence of 0.1 g yeast extract l−1. The DNA G+C content of strain MCT was 43.3 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain MCT within the genus Caldithrix. However, strain MCT possessed certain phenotypic features that differentiated it from the type strain of the only species of the genus Caldithrix described to date. On the basis of phylogenetic and phenotypic characteristics, it is proposed that strain MCT represents a novel species, Caldithrix palaeochoryensis sp. nov. The type strain is MCT (=DSM 21940T =VKM B-2536T). In addition, an emended description of the genus Caldithrix is presented.

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

The 16S Rrna Gene

The taxonomic status of the species Clostridium methoxybenzovorans was assessed. The 16S rRNA gene sequence, whole-genome sequence and phenotypic characterizations suggested that the type strain deposited in the American Type Culture Collection ( C. methoxybenzovorans ATCC 700855T) is a member of the species Eubacterium callanderi . Hence, C. methoxybenzovorans ATCC 700855T cannot be used as a reference for taxonomic study. The type strain deposited in the German Collection of Microorganism and Cell Cultures GmbH (DSM 12182T) is no longer listed in its online catalogue. Also, both the 16S rRNA gene and the whole-genome sequences of the original strain SR3T showed high sequence identity with those of Lacrimispora indolis (recently reclassified from Clostridium indolis ) as the most closely related species. Analysis of the two genomes showed average nucleotide identity based on blast and digital DNA–DNA hybridization values of 98.3 and 87.9 %, respectively. Based on these results, C. methoxybenzovorans SR3T was considered to be a member of L. indolis .

Four novel strains isolated from the cloacal contents of snow finches (Montifringilla taczanowskii) were characterized as aerobic, Gram-stain-negative, slightly motile, and rod-shaped. Analysis of the 16S rRNA gene sequence revealed that strain CF-458T had the highest similarities of 96.9 and 96.4 % with Limnobaculum parvum HYN0051T and Pragia fontium DSM 5563T, while strain CF-1111T shared the highest similarities of 96.4 and 96.1 % with Pantoea rodasii LMG 26273T and Pectobacterium punjabense SS95T. Phylogenomic analysis showed the four isolates were separated into group Ⅰ (CF-458T and CF-917) and group Ⅱ (CF-1111T and CF-509), and clustered independently in the vicinity of the genera Limnobaculum and Pragia . Summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c, 23.9 and 17.2 %, respectively), C16 : 0 (21.8 and 22.1 %, respectively) and C14 : 0 (10.6 and 17.7 %, respectively) were the common major fatty acids, and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c, 12.3 %) was also a major fatty acid for strain CF-458T while cyclo-C17 : 0 (13.1%) was for strain CF-1111T. Both had Q-8 as the sole quinone and contained phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol as the major polar lipids. The DNA G+C content of strains CF-458T and CF-1111T was 45.7 and 45.4 mol%, respectively. Based on taxonomic position in the phylogenomic tree and phenotypic properties, two novel species of a new genus within the family Budviciaceae are thus proposed, with the name Jinshanibacter gen. nov., zhutongyuii sp. nov. (type strain CF-458T=CGMCC 1.16483T=GDMCC 1.1586T=JCM 33489T) and Jinshanibacter xujianqingii sp. nov. (type strain CF-1111T=CGMCC 1.16786T=GDMCC 1.1587T=JCM 33490T), respectively.

Five Gram-negative, motile, spiral-shaped strains were isolated from a sulfide spring (D-412T), active sludge of wastewater (D-419T, D-420, D-424) and industrial wastewater (D-416). Comparative 16S rRNA gene sequence analysis showed that the isolates belong to the family Comamonadaceae, within the class Betaproteobacteria, but fall into a distinct cluster. On the basis of phenotypic, chemotaxonomic and phylogenetic data, a new genus, Giesbergeria gen. nov., is proposed, including five species. The type species of the genus is Giesbergeria voronezhensis sp. nov. (type strain D-419T=DSM 12825T=CIP 107340T=VKM B-2350T) and other novel members of the genus are Giesbergeria kuznetsovii sp. nov. (type strain D-412T=DSM 12827T=VKM B-2352T), Giesbergeria giesbergeri comb. nov. (basonym Aquaspirillum giesbergeri), Giesbergeria sinuosa comb. nov. (basonym Aquaspirillum sinuosum) and Giesbergeria anulus comb. nov. (basonym Aquaspirillum anulus). Using the same criteria, isolate D-416 (=DSM 12826) was identified as a strain of [Aquaspirillum] metamorphum. Strain D-416, the type strain of [A.] metamorphum and the type strain of [Aquaspirillum] psychrophilum form a distinct cluster within the family Comamonadaceae (97–97·2 % 16S rRNA gene sequence similarity) and share phenotypic and chemotaxonomic properties. Therefore, it is proposed that these strains are reclassified as members of a new genus, Simplicispira gen. nov., as Simplicispira metamorpha comb. nov. (the type species) and Simplicispira psychrophila comb. nov., respectively.

An actinobacterial strain was isolated from marine sediment taken from the Troitsa Bay of the Gulf of Peter the Great, East Siberian Sea, and subjected to a taxonomic investigation. The isolate, designated KMM 3905T, was Gram-positive, aerobic, non-motile and coccoid. The strain tolerated up to 15 % NaCl in growth media, although its presence was not essential for growth. Chemotaxonomic and phylogenetic properties of the strain were consistent with its classification in the genus Kocuria. The strain formed an independent phylogenetic line in the 16S rRNA gene tree encompassed by members of Kocuria. Comparison of phenotypic characteristics also supported its assignment to a novel species within Kocuria. The name Kocuria marina sp. nov. (type strain KMM 3905T=KCTC 9943T) is proposed for this halotolerant actinobacterium from the marine environment.

Four Gram-staining-positive, catalase-negative, coccoid isolates, designated NTUH_1465T, NTUH_2196, NTUH_4957 and NTUH_5572T, were isolated from human specimens. The four isolates displayed more than 99.6 % 16S rRNA gene sequence similarity with Gemella haemolysans ATCC 10379T, and 96.7 to 98.6 % similarity with Gemella sanguinis ATCC 700632T, Gemella morbillorum ATCC 27824T or Gemella cuniculi CCUG 42726T. However, phylogenetic analysis of concatenated sequences of three housekeeping genes, groEL, rpoB and recA, suggested that the four isolates were distinct from G. haemolysans ATCC 10379T and other species. Isolates NTUH_2196, NTUH_4957 and NTUH_5572T clustered together and formed a stable monophyletic clade. DNA–DNA hybridization values among strains NTUH_1465T and NTUH_5572T and their phylogenetically related neighbours were all lower than 49 %. The four isolates could be distinguished from G. haemolysans and other species by phenotypic characteristics. Based on the phylogenetic and phenotypic results, two novel species Gemella parahaemolysans sp. nov. (type strain NTUH_1465T = BCRC 80365T = JCM 18067T) and Gemella taiwanensis sp. nov. (type strain NTUH_5572T = BCRC 80366T = JCM 18066T) are proposed.

Distinct Evolutionary Lineage

A whitish Gram-negative, motile, aerobic bacterium, designated strain H 14T, was isolated from seawater collected at St Kilda beach in Port Phillip Bay, Melbourne, Australia. Analysis of 16S rRNA gene sequences revealed that the organism belonged to the Roseobacter lineage of the class Alphaproteobacteria, forming a distinct evolutionary lineage at the genus level. Strain H 14T was distantly related to the genera Nautella, Ruegeria and Pseudoruegeria (family Rhodobacteraceae). Strain H 14T was unable to degrade gelatin, casein, chitin, agar and starch, did not produce any carotenoids, did not possess bacteriochlorophyll a and had a limited ability to utilize carbon sources. Strain H 14T grew with concentrations of 1–8 % (w/v) NaCl and over a temperature range of 5–35 °C. Phosphatidylglycerol was the major phospholipid (90 %); phosphatidylcholine (7.9 %) and phosphatidylethanolamine (2.0 %) were present in minor quantities. The predominant fatty acids were C18 : 1 ω7c (82.4 %), C18 : 1 ω9c (5.1 %) and C18 : 0 (3.8 %). The DNA G+C composition for strain H 14T was 59.1 mol%. Based on the results of physiological, biochemical, chemotaxonomic and phylogenetic investigations, a new genus, Celeribacter gen. nov., with the type species Celeribacter neptunius sp. nov. is proposed. The type strain of the type species is H 14T (=KMM 6012T=CIP 109922T).

Hydrolysis Of

A Gram-negative, helical bacterium designated PH27AT was cultivated from an anchialine pool on Pearl and Hermes Atoll, Northwestern Hawaiian Islands. The obligately halophilic strain was motile by bipolar tufts of flagella and grew optimally at pH 7, and microaerobically or aerobically. Closest neighbours based on 16S rRNA gene nucleotide sequence identity are Marinospirillum celere v1c_Sn-redT (93.31 %) and M. alkaliphilum Z4T (92.10 %) in the family Oceanospirillaceae, class Gammaproteobacteria. PH27AT is distinguished phenotypically from members of the genus Marinospirillum by its hydrolysis of gelatin, the absence of growth in media containing ≤ 1 % (w/v) NaCl and the ranges of temperature (12–40 °C) and pH (5–8) for growth. The major compound ubiquinone Q-9 distinguishes the quinone system of strain PH27AT from those in members of the genus Marinospirillum and other members of the Oceanospirillaceae, in which the major quinone is Q-8. Major polar lipids in PH27AT were phosphatidylethanolamine and phosphatidylglycerol, with moderate amounts of diphosphatidylglycerol and phosphatidylserine. Spermidine and cadaverine dominated the polyamine pattern; large proportions of cadaverine have not been reported in members of the genus Marinospirillum. Genotypic and chemotaxonomic data show that PH27AT does not belong in the genus Marinospirillum or other genera of the family Oceanospirillaceae or the Halomonadaceae. We propose a new genus, Terasakiispira gen. nov., be created to accommodate Terasakiispira papahanaumokuakeensis gen. nov., sp. nov. as the type species, with PH27AT ( = ATCC BAA-995T = DSM 16455T = DSM 23961T) as the type strain.
