The 16S Rrna Gene

A Gram-stain-negative, aerobic, rod-shaped, non-spore-forming bacterium (SV325T) was isolated from the sediment of a hypersaline lake located 4600 m above sea level (Laguna Vilama, Argentina). Strain SV325T formed cream to pink colonies, was motile and moderately halophilic, and tolerated NaCl concentrations of 1–25 % (w/v) with an optimum of 5–10 % (w/v). Growth occurred at 5–40 °C (optimum around 30 °C) and at pH 5.0–10.0 (optimum 7.0–8.0). The bacterium did not produce exopolysaccharides and stained positively for intracellular polyphosphate granules but not for poly-β-hydroxyalkanoates. It produced catalase and oxidase, reduced nitrate to nitrite, hydrolysed gelatin, did not produce acids from sugars and utilized a limited range of substrates as carbon and energy sources: acetate, caproate, fumarate, dl-β-hydroxybutyrate, malate, maleate, malonate and succinate. The predominant ubiquinones were Q-9 (92.5 %) and Q-8 (7.5 %), the major fatty acids were C19 : 0 cyclo ω8c, C16 : 0, C17 : 0 cyclo and C16 : 1ω7c/iso-C15:0 2-OH, and the DNA G+C content was 55.0 mol%. Phylogenetic analyses based on the 16S rRNA gene indicated that strain SV325T belongs to the genus Halomonas in the class Gammaproteobacteria. Physiological and biochemical tests allowed phenotypic differentiation of strain SV325T from closely related species with validly published names. We therefore propose a novel species, Halomonas vilamensis sp. nov., with type strain SV325T ( = DSM 21020T  = LMG 24332T).

The 16S Rrna Gene

Two moderately halophilic Gram-negative bacteria were isolated from a sample taken from the brine–seawater interface of the Shaban Deep in the Red Sea. Phylogenetic analysis of the 16S rRNA gene sequence showed that these organisms represent a novel species of the genus Marinobacter. Cells of the new isolates formed non-pigmented colonies and were motile by means of a single polar flagellum. Strains SD-14BT and SD-14C grew optimally at 35–37 °C, in 5 % NaCl and at pH 7.5–8.0. The organisms were aerobic, but reduced nitrate to nitrogen under anaerobic conditions. Acid was produced from only a few carbohydrates. Ubiquinone 9 was the major respiratory quinone. The major fatty acids of strains SD-14BT and SD-14C were C16 : 0, C18 : 1 ω9c, summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c) and C12 : 0 3-OH. The DNA G+C contents were 55.9 and 55.7 mol%, respectively. On the basis of the phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strains SD-14BT and SD-14C represent a novel species of the genus Marinobacter, with the name Marinobacter salsuginis sp. nov. The type strain is strain SD-14BT (=DSM 18347T=LMG 23697T).

A Gram-negative, rod-shaped, non-spore-forming bacteria was isolated from a nitrifying inoculum. On the basis of 16S rRNA gene sequence similarity, this strain, designated LMG 22951T, was shown to belong to the ‘Alphaproteobacteria’ and to be related to Devosia neptuniae (97·4 %) and Devosia riboflavina (97·0 %). The results of DNA–DNA hybridization, analysis of fatty acid composition, SDS-PAGE, physiological and biochemical tests allowed genotypic and phenotypic differentiation of LMG 22951T from the two recognized Devosia species. LMG 22951T therefore represents a novel species within this genus, for which the name Devosia limi is proposed. The type strain is LMG 22951T (=DSM 17137T).

A Gram-negative, rod-shaped, non-spore-forming bacterium (strain NS11T) was isolated from a lichen-colonized rock surface. On the basis of 16S rRNA gene sequence similarity, strain NS11T was shown to belong to the Betaproteobacteria, and was most closely related to Herminiimonas arsenicoxydans ULPAs1T (98.8 %), Herminiimonas aquatilis CCUG 36956T (98.0 %) and Herminiimonas fonticola S-94T (98.0 %). Major whole-cell fatty acids were C16 : 0, C17 : 0 cyclo and C16 : 1 ω7c. Strain NS11T also contained high proportions of C10 : 0 3-OH and C18 : 1 ω7c. This pattern is typical for members of the genus Herminiimonas. The results of DNA–DNA hybridization experiments and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain NS11T from the three recognized Herminiimonas species. It is therefore concluded that strain NS11T represents a novel species of the genus Herminiimonas, for which the name Herminiimonas saxobsidens sp. nov. is proposed. The type strain is NS11T (=DSM 18748T=CCM 7436T).

A Gram-negative, rod-shaped, non-spore-forming bacterial strain, designated LMG 2337T, was isolated from the blood of a patient with endocarditis and characterized. The strain was affiliated with the alphaproteobacterial genus Brevundimonas, with Brevundimonas diminuta LMG 2089T (98.3 % 16S rRNA gene sequence similarity) and Brevundimonas terrae KSL-145T (97.5 %) as its closest relatives. This affiliation was supported by chemotaxonomic data: the G+C content was 66.3 mol %, the major polar lipids were phosphatidyl diacylglycerol, sulfoquinovosyl diacylglycerol and phosphatidyl glucopyranosyl diacylglycerol and the major fatty acids were summed feature 7 (one or more of C18 : 1 ω7c, C18 : 1 ω9t and C18 : 1 ω12t) and C16 : 0. Strain LMG 2337T displayed an unusually broad substrate spectrum. The results from DNA–DNA hybridization and physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain LMG 2337T from all of the type strains of hitherto-described Brevundimonas species. The strain therefore represents a novel species, for which the name Brevundimonas vancanneytii sp. nov. is proposed, with type strain LMG 2337T (=CCUG 1797T =ATCC 14736T).

In total 14 strains of Gram-stain-negative, rod-shaped bacteria were isolated from Sophora longicarinata and Sophora microphylla root nodules and authenticated as rhizobia on these hosts. Based on the 16S rRNA gene phylogeny, they were shown to belong to the genus Mesorhizobium, and the strains from S. longicarinata were most closely related to Mesorhizobium amorphae ACCC 19665T (99.8–99.9 %), Mesorhizobium huakuii IAM 14158T (99.8–99.9 %), Mesorhizobium loti USDA 3471T (99.5–99.9 %) and Mesorhizobium septentrionale SDW 014T (99.6–99.8 %), whilst the strains from S. microphylla were most closely related to Mesorhizobium ciceri UPM-Ca7T (99.8–99.9 %), Mesorhizobium qingshengii CCBAU 33460T (99.7 %) and Mesorhizobium shangrilense CCBAU 65327T (99.6 %). Additionally, these strains formed two distinct groups in phylogenetic trees of the housekeeping genes glnII, recA and rpoB. Chemotaxonomic data, including fatty acid profiles, supported the assignment of the strains to the genus Mesorhizobium and allowed differentiation from the closest neighbours. Results of DNA–DNA hybridizations, MALDI-TOF MS analysis, ERIC-PCR, and physiological and biochemical tests allowed genotypic and phenotypic differentiation of our strains from their closest neighbouring species. Therefore, the strains isolated from S. longicarinata and S. microphylla represent two novel species for which the names Mesorhizobium waimense sp. nov. (ICMP 19557T = LMG 28228T = HAMBI 3608T) and Mesorhizobium cantuariense sp. nov. (ICMP 19515T = LMG 28225T = HAMBI 3604T), are proposed respectively.

Eight strains of Gram-negative, bacteroid-shaped, prosthecate bacteria, isolated from brackish water (MCS24T, MCS17 and MCS35), the marine environment (CM260, CM272 and CM282) and activated sludge (FWC40T and FWC43T), were characterized using a polyphasic approach. Analysis of 16S rRNA gene sequences determined that all strains were affiliated to the alphaproteobacterial genus Brevundimonas, forming three distinct phyletic lineages within the genus. The strains grew best with 5–30 g NaCl l−1 at 20–30 °C. DNA G+C contents for strains MCS24T, FWC40T and FWC43T were between 65 and 67 mol%, in accordance with values reported previously for other species of the genus. Moreover, chemotaxonomic data and physiological and biochemical tests allowed the phenotypic differentiation of three novel species within the genus Brevundimonas, for which the names Brevundimonas halotolerans sp. nov. (type strain MCS24T =LMG 25346T =CCUG 58273T), Brevundimonas poindexterae sp. nov. (type strain FWC40T =LMG 25261T =CCUG 57883T) and Brevundimonas staleyi sp. nov. (type strain FWC43T =LMG 25262T =CCUG 57884T) are proposed.

Two Gram-negative, rod-shaped, non-spore-forming bacteria (CCUG 39402T and CCUG 39797), isolated from different water sources, were investigated in a polyphasic study. The two isolates shared 100 % 16S rRNA gene sequence similarity and it was shown that they belonged to the Betaproteobacteria, most closely related to Polaromonas vacuolata (97·8 %) and Polaromonas naphthalenivorans (97·8 %). A polyamine pattern with 2-hydroxyputrescine and putrescine, as well as ubiquinone Q-8, were in agreement with characteristics of Betaproteobacteria. The presence of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, and major fatty acids C16 : 1 ω7c, C16 : 0 and C17 : 0 cyclo supported the affiliation of the two strains to the genus Polaromonas. The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the two isolates from the two Polaromonas species with validly published names. They therefore represent a novel species, for which the name Polaromonas aquatica sp. nov. is proposed, with the type strain CCUG 39402T (=CIP 108776T).

A bacterial strain, designated Nsw-4T, was isolated from a water sample of Niao-Song Wetland Park in Taiwan and was characterized by using a polyphasic taxonomic approach. Strain Nsw-4T was Gram-negative, aerobic, ivory-coloured, rod-shaped and motile by means of a polar flagellum. Growth occurred at 15–37 °C, pH 6.0–8.0 and 0–2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain belonged to the genus Deefgea and that its closest neighbour was Deefgea rivuli WB 3.4-79T (96.9 %). The results of physiological and biochemical tests allowed the clear phenotypic differentiation of this isolate from D. rivuli WB 3.4-79T. The major fatty acids were C16 : 1ω7c and C16 : 0. The G+C content of the genomic DNA was 53.7 mol%. On the basis of 16S rRNA gene sequence analysis and the chemotaxonomic and physiological data, strain Nsw-4T should be classified as representing a novel species and the second member of the genus Deefgea, for which the name Deefgea chitinilytica sp. nov. is proposed. The type strain is Nsw-4T (=BCRC 17934T=LMG 24817T).

A Gram-positive, aerobic, non-motile actinomycete, strain MN08-A0203T, that formed pale yellow to orange-brown colonies and non-fragmented branched substrate mycelium is described. The strain, which produced very scanty aerial mycelium-like structures and scanty formation of spherical bodies on the aerial mycelium on Bennett’s agar medium, was studied in detail to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity studies, strain MN08-A0203T grouped with the genus Actinophytocola, being most closely related to the type strain of Actinophytocola oryzae (97.8 %). Chemotaxonomic data [menaquinone MK-9(H4); iso-C16 : 0 (27 %), iso-C15 : 0 (18 %), C16 : 1 H (8 %), C16 : 0 9-methyl (8 %) as major fatty acids; glucose, galactose, ribose, arabinose, mannose, rhamnose and xylose (trace) as whole cell sugars; diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine and ninhydrin-positive phosphoglycolipids as polar phospholipids] supported allocation of the strain to the genus Actinophytocola. Furthermore, the results of DNA–DNA hybridization of strain MN08-A0203T with the type strain of Actinophytocola oryzae revealed that the two strains were genetically distinct from each other. Moreover, physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain MN08-A0203T from closely related species. Thus, MN08-A0203T represents a novel species of the genus Actinophytocola, for which the name Actinophytocola burenkhanensis sp. nov. is proposed, with MN08-A0203T ( = NBRC 105883T  = VTCC D9-23T) as the type strain.

An actinomycete strain, NAR01T, was isolated from root nodules of a Coriaria plant. The 16S rRNA gene sequence of strain NAR01T showed most similarity to the type strains of Micromonospora endolithica (98.94 %) and Micromonospora chersina (98.4 %). The chemotaxonomic results obtained confirmed the taxonomic position of the isolate within the genus Micromonospora, and revealed differences at the species level. Physiological and biochemical tests showed that strain NAR01T could be clearly distinguished from its closest phylogenetic neighbours, while DNA–DNA hybridization results indicated that the isolate represents a novel species. On the basis of these results, strain NAR01T (=DSM 44875T=LMG 23557T) is proposed as the type strain of the novel species Micromonospora coriariae sp. nov.
