Xylanibacterium ulmi gen. nov., sp. nov., a novel xylanolytic member of the family Promicromonosporaceae.

A bacterial strain designated XIL08(T) was isolated from an elm tree affected by Dutch elm disease. Strain XIL08(T) is Gram-positive, aerobic, rod-shaped and non-motile. The complete 16S rDNA sequence of this micro-organism was obtained and phylogenetic analysis based on the neighbour-joining method indicated that the closest related organism belongs to the genus Xylanimonas of the family Promicromonosporaceae, suborder Micrococcineae. Cell-wall analyses revealed the presence of type A4alpha, L-lys-L-ala-D-Glu peptidoglycan. The cell-wall sugars found were rhamnose in large amounts, fucose, mannose and galactose and traces of arabinose and glucose. HPLC analysis of menaquinones revealed two peaks, the main peak corresponding to MK-9(H(4)) and the smaller one to MK-8(H(4)). The major fatty acid found was anteiso-C(15 : 0). Mycolic acids were absent. The polar lipids detected were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The G+C content of the DNA was 72 mol%. Isolate XIL08(T) hydrolysed xylan but not cellulose. Growth was observed with many carbohydrates including acetate and xylan as the only carbon source. Catalase activity was not detected. The data from this polyphasic study suggest that this bacterium belongs to a novel genus of the family Promicromonosporaceae. It is proposed that isolate XIL08(T) (=LMG 21721(T)=CECT 5731(T)) be classified in a new genus, Xylanibacterium gen. nov., as the type strain of Xylanibacterium ulmi sp. nov.

Nocardiopsis aegyptia sp. nov., isolated from marine sediment.

An actinomycete, strain SNG49(T), was isolated from marine sediment of Abu Qir Bay, on the western seashore of Alexandria, Egypt. The bacterium was aerobic and Gram-positive. It produced beige to light-yellow aerial mycelium, brown substrate mycelium and straight to flexuous hyphae, but no specific spore chains. 16S rDNA sequence analysis and chemotaxonomic markers were consistent with classification of strain SNG49(T) in the genus Nocardiopsis, i.e. meso-diaminopimelic acid; no diagnostic sugars; phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylglycerol and diphosphatidylglycerol as polar lipids; menaquinones of the MK-10 series from MK-10(H(0)) to MK-10(H(8)); and iso/anteiso-branched and 10-methyl-branched fatty acids, the principal fatty acids being anteiso-17 : 0 and tuberculostearic acid. Nocardiopsis lucentensis and Nocardiopsis alba are the phylogenetic neighbours of strain SNG49(T), respectively showing 98.8 and 98.7 % 16S rRNA gene sequence similarity; however, moderate DNA-DNA reassociation values between these two species and strain SNG49(T) (44 and 60 %, respectively) showed that strain SNG49(T) could be clearly separated from them. These data, together with distinct physiological traits, led to the conclusion that this isolate represents a novel species within the genus Nocardiopsis, for which the name Nocardiopsis aegyptia is proposed. The type strain is SNG49(T) (=DSM 44442(T)=NRRL B-24244(T)).

Psychrophilic pseudomonads from Antarctica: Pseudomonas antarctica sp. nov., Pseudomonas meridiana sp. nov. and Pseudomonas proteolytica sp. nov.

Thirty-one bacteria that belonged to the genus Pseudomonas were isolated from cyanobacterial mat samples that were collected from various water bodies in Antarctica. All 31 isolates were psychrophilic; they could be divided into three groups, based on their protein profiles. Representative strains of each of the three groups, namely CMS 35(T), CMS 38(T) and CMS 64(T), were studied in detail. Based on 16S rRNA gene sequence analysis, it was established that the strains were related closely to the Pseudomonas fluorescens group. Phenotypic and chemotaxonomic characteristics further confirmed their affiliation to this group. The three strains could also be differentiated from each other and the closely related species Pseudomonas orientalis, Pseudomonas brenneri and Pseudomonas migulae, based on phenotypic and chemotaxonomic characteristics and the level of DNA-DNA hybridization. Therefore, it is proposed that strains CMS 35(T) (=MTCC 4992(T)=DSM 15318(T)), CMS 38(T) (=MTCC 4993(T)=DSM 15319(T)) and CMS 64(T) (=MTCC 4994(T)=DSM 15321(T)) should be assigned to novel species of the genus Pseudomonas as Pseudomonas antarctica sp. nov., Pseudomonas meridiana sp. nov. and Pseudomonas proteolytica sp. nov., respectively.

Jeotgalicoccus pinnipedialis sp. nov., from a southern elephant seal (Mirounga leonina).

A previously unknown Gram-positive, catalase-positive, facultatively anaerobic, non-spore-forming, coccus-shaped bacterium (A/G14/99/10(T)), originating from the mouth of a female southern elephant seal, was subjected to a taxonomic analysis. Comparative 16S rRNA gene-sequencing showed that the organism formed a hitherto unknown subline within the catalase-positive, low-G+C, Gram-positive cocci, exhibiting a specific association with species of the genus Jeotgalicoccus. Sequence divergence values of approximately 7 %, together with phenotypic differences, showed the unknown bacterium to be distinct from the two described species of this genus, Jeotgalicoccus halotolerans and Jeotgalicoccus psychrophilus. Based on phenotypic and phylogenetic considerations, it is proposed that strain A/G14/99/10(T)=CCUG 42722(T)=CIP 107946(T) from the mouth of a seal be classified as the type strain of a novel species of the genus Jeotgalicoccus, Jeotgalicoccus pinnipedialis sp. nov.

Reinekea marinisedimentorum gen. nov., sp. nov., a novel gammaproteobacterium from marine coastal sediments.

A Gram-negative, oxidase- and catalase-positive, rod-shaped bacterium, designated strain KMM 3655(T), was isolated from a coastal marine sediment sample. The novel bacterium required sodium ions for growth and grew between 0.5 and 5 % NaCl and at 4-37 degrees C, but not at 40 degrees C. It reduced nitrate, formed acids from glucose under aerobic and anaerobic conditions, utilized a limited spectrum of organic substrates and did not produce gelatinase, caseinase, amylase or chitinase. The major isoprenoid quinone was Q8. Polar lipids consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and an unknown phospholipid. Fatty acid analysis of strain KMM 3655(T) revealed C(16 : 0), C(16 : 1)omega7c and C(18 : 1)omega7c as predominant components. The G+C content of the DNA was 51.1 mol%. Phylogenetic analysis of the 16S rDNA sequence placed the new isolate within the gamma-Proteobacteria as a separate deep branch, with about 90 % sequence similarity to representatives of the genus Oceanospirillum and other remotely related genera. Combined phylogenetic and physiological data show that the new marine sediment isolate, KMM 3655(T), represents a novel genus and species, for which the name Reinekea marinisedimentorum gen. nov., sp. nov. is proposed. The type strain is KMM 3655(T) (=DSM 15388(T)).

Yania halotolerans gen. nov., sp. nov., a novel member of the suborder Micrococcineae from saline soil in China.

A novel coccoid, halotolerant actinobacterium, designated strain YIM 70085(T), was isolated from a soil sample that was collected in Xinjiang Province, China, and characterized by using a polyphasic approach. Optimum growth temperature was 28 degrees C and growth occurred optimally in culture media that contained 10 % KCl. The peptidoglycan type was A4alpha, L-lys-gly-L-Glu. Whole-cell sugars consisted of xylose, mannose and galactose. Phospholipids were diphosphatidylglycerol, phosphatidylglycerol, one unknown phospholipid, one unknown glycolipid and traces of phosphatidylinositol. Menaquinones were MK-8 (83 %), MK-7 (12 %) and MK-9 (15 %). Predominant fatty acids were i-C(15 : 0) (44.29 %), ai-C(15 : 0) (35.60 %) and ai-C(17 : 0) (9.74 %). The DNA G+C content was 53.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 70085(T) occupies a branch that is distinct from, although very close to, the family Micrococcaceae in the suborder Micrococcineae. Based on its phenotypic characteristics, phylogenetic position (as determined by 16S rRNA gene sequence analysis) and 16S rDNA signature nucleotide data, it is concluded that the isolate represents a novel member of the suborder Micrococcineae, for which the name Yania halotolerans gen. nov., sp. nov. is proposed. The type strain is YIM 70085(T) (=CCTCC AA001023(T)=DSM 15476(T)).

Reclassification of Cellulosimicrobium variabile Bakalidou et al. 2002 as Isoptericola variabilis gen. nov., comb. nov.

As already depicted in the original publication, the type strain of the species Cellulosimicrobium variabile Bakalidou et al. 2002, DSM 10177(T), does not cluster unambiguously with the type species, Cellulosimicrobium cellulans DSM 43879(T), in phylogenetic analysis. Strain DSM 10177(T) is moderately related to the recently described species Xylanimonas cellulosilytica, Promicromonospora pachnodae and Xylanibacterium ulmi, forming a lineage that branches between C. cellulans and members of the genus Promicromonospora in most dendrograms generated on the basis of different algorithms and reference strains. The type strains of the two Cellulosimicrobium species resemble each other in morphology, composition of fatty acids, DNA G+C content, phospholipids and the presence of lysine in position 3 of the peptide subunit of peptidoglycan. However, the two strains differ from each other in cell-wall sugars and in the amino acid composition of the A4alpha-type peptidoglycan, which contains serine and aspartic acid in C. cellulans, whereas only aspartic acid is present in the interpeptide bridge of C. variabile. This type is also present in Xylanimonas cellulosilytica XIL07(T), but not in the neighbouring species P. pachnodae DSM 12657(T), which exhibits the L-lys-L-ser-D-Glu type. On the basis of distinct phylogenetic position and the amino acid composition of peptidoglycan, a novel genus and combination for C. variabile, Isoptericola variabilis gen. nov., comb. nov., is proposed.

Erysipelothrix inopinata sp. nov., isolated in the course of sterile filtration of vegetable peptone broth, and description of Erysipelotrichaceae fam. nov.

Based on 16S rRNA gene sequence comparison, an isolate that was detected in sterile-filtered vegetable broth was classified as a novel member of the Erysipelothrix line of descent of the Firmicutes. Strain MF-EP02T resembles members of the two species of Erysipelothrix with validly published names, Erysipelothrix rhusiopathiae and Erysipelothrix tonsillarum, in morphology, fatty acid composition, lack of menaquinones in aerobically and anaerobically grown cultures, DNA G+C content and peptidoglycan amino acid composition. Distinct differences in physiological characteristics, however, support the allocation of this isolate to a novel species of the genus Erysipelothrix, for which the name Erysipelothrix inopinata sp. nov. (type strain, MF-EP02T=DSM 15511T=CIP 107935T) is proposed. Members of the Erysipelothrix line of descent are included in the family Erysipelotrichaceae fam. nov.

Arsenicicoccus bolidensis gen. nov., sp. nov., a novel actinomycete isolated from contaminated lake sediment.

An unknown Gram-positive, catalase-positive, facultatively anaerobic, non-spore-forming, coccus-shaped bacterium originating from sediment was characterized using phenotypic, molecular chemical and molecular phylogenetic methods. Chemical studies revealed the presence of a cell-wall murein based on LL-diaminopimelic acid (type LL-Dpm-glycine(1)), a complex mixture of saturated, monounsaturated and iso- and anteiso-methyl-branched, non-hydroxylated, long-chain cellular fatty acids and tetrahydrogenated menaquinones with eight isoprene units [MK-8(H(4))] as the major respiratory lipoquinone. This combination of characteristics somewhat resembled members of the suborder Micrococcineae, but did not correspond to any currently described species. Comparative 16S rRNA gene sequencing confirmed that the unidentified coccus-shaped organism is a member of the Actinobacteria and represents a hitherto-unknown subline related to, albeit different from, a number of taxa including Intrasporangium, Janibacter, Terrabacter, Terracoccus and Ornithinicoccus. Based on phenotypic and phylogenetic considerations, it is proposed that the unknown bacterium originating from lake sediment be classified as a new genus and species, Arsenicicoccus bolidensis gen. nov., sp. nov. (type strain CCUG 47306(T)=DSM 15745(T)).

Arthrobacter nitroguajacolicus sp. nov., a novel 4-nitroguaiacol-degrading actinobacterium.

Three bacterial isolates from soil, capable of degradation or transformation of nitroaromatic compounds and displaying a rod-coccus growth cycle, were studied by a polyphasic approach. On the basis of 16S rRNA sequence analysis and of chemotaxonomic characteristics, such as type A3alpha peptidoglycan with an interpeptide bridge Ala-Thr-Ala, the major menaquinone MK-9(H(2)) and fatty acid composition, the isolates were assigned to the genus Arthrobacter. DNA-DNA hybridization, riboprinting and phenotypic studies revealed that the three strains constitute a single species, distinct from phylogenetically neighbouring Arthrobacter aurescens and Arthrobacter ilicis. A novel species, Arthrobacter nitroguajacolicus sp. nov., with the type strain G2-1(T) (=CCM 4924(T)=DSM 15232(T)) is proposed.

Nesterenkonia halotolerans sp. nov. and Nesterenkonia xinjiangensis sp. nov., actinobacteria from saline soils in the west of China.

The taxonomic position of two Gram-positive strains, YIM 70084(T) and YIM 70097(T), isolated from hypersaline soils was determined by a polyphasic approach. Cells of strain YIM 70084(T) are motile cocci, whereas those of strain YIM 70097(T) are non-motile rods. The G+C contents of their DNA are 64.4 and 66.7 mol%. Both strains had chemotaxonomic markers typical of the genus Nesterenkonia and formed a coherent cluster with Nesterenkonia species in a phylogenetic inference based on 16S rDNA sequence analysis, exhibiting less than 97 % similarity to each other and to the other two type strains of the genus. Phylogenetic distinction and differences in the peptidoglycan type, composition of cell-wall sugars, phospholipid patterns, the major menaquinones and other phenotypic characteristics indicate that the strains under study represent two novel species, Nesterenkonia halotolerans sp. nov. (type strain YIM 70084(T)=CCTCC AA 001022(T)=DSM 15474(T)) and Nesterenkonia xinjiangensis sp. nov. (type strain YIM 70097(T)=CCTCC AA 001025(T)=DSM 15475(T)).

Mycobacterium psychrotolerans sp. nov., isolated from pond water near a uranium mine.

An acid-fast, rapidly growing, psychrotolerant short rod was isolated from pond water near a uranium mine. Phylogenetic analysis of the 16S rRNA gene sequence grouped this strain with the rapidly growing mycobacteria. The 16S rRNA gene sequence of isolate WA101T showed highest similarity to that of Mycobacterium sphagni DSM 44076T; however, DNA-DNA relatedness between the two strains was less than 30 %. Chemotaxonomic analyses, which included fatty acid and mycolic acid patterns, confirmed the classification of strain WA101T in the genus Mycobacterium. Physiological data, including antibiotic resistance, NaCl tolerance, carbon sources, temperature growth range and enzyme activities, were also determined. Based on the genotypic and phenotypic results it is proposed that isolate WA101T represents a novel Mycobacterium species. The name Mycobacterium psychrotolerans sp. nov. is proposed, with type strain WA101T (= DSM 44697T = LMG 21953T).

Serinicoccus marinus gen. nov., sp. nov., a novel actinomycete with L-ornithine and L-serine in the peptidoglycan.

A Gram-positive bacterial strain containing L-ornithine as the diagnostic diamino acid was isolated from a sea-water-sample from the East Sea, Korea. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain JC1078T represents a phyletic line within the suborder Micrococcineae of the order Actinomycetales, adjacent to the genus Ornithinimicrobium. The highest sequence similarity values to the isolate were observed against Ornithinimicrobium humiphilum (94.3 %) and Kytococcus sedentarius (94.1 %). The strain was strictly aerobic and moderately halophilic with optimal growth at 2-3 % (w/v) NaCl. Cells were non-motile, non-sporulating and coccoid-shaped. The cell wall contains L-ornithine, glutamic acid, alanine, glycine and serine. The major menaquinone was MK-8(H4). The predominant cellular fatty acids were of the iso- and anteiso-methyl-branched types. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unknown glycolipid. The acyl type of the glycan chain of peptidoglycan is acetyl. The DNA G + C content was 72 mol%. The combination of physiological, biochemical and chemotaxonomical data clearly separated the marine isolate from other members of the suborder Micrococcineae. On the basis of polyphasic evidence, it is proposed to classify strain JC1078T in a novel genus and species, for which the name Serinicoccus marinus gen. nov., sp. nov. is proposed. The type strain is JC1078T (= IMSNU 14026T = KCTC 9980T = DSM 15273T).

Myceligenerans xiligouense gen. nov., sp. nov., a novel hyphae-forming member of the family Promicromonosporaceae.

Strain XLG9A10.2T was isolated from an alkaline salt marsh soil in western China. 16S rRNA gene sequence analysis indicated that strain XLG9A10.2T constitutes a distinct lineage within the family Promicromonosporaceae, sharing 94.8-95.1% gene similarity with members of the genus Promicromonospora and 94.4-95.7% similarity with those of Xylanimonas and related genera. The general colony and cell morphology of strain XLG9A10.2T is similar to that of members of Promicromonospora, but differs from members of the genus Xylanimonas in forming a well-developed branching mycelium and production of coccoid spores. Strain XLG9A10.2T shows the peptidoglycan type A4alpha (L-lys<--L-thr<--D-Glu), contains glucose, mannose and galactose as whole cell sugars and has MK-9(H4) and MK-9(H6) as major menaquinones, while phospholipids are phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, three unidentified phospholipids and one unidentified glycolipid. The DNA base composition is 71.9 mol% G+C. On the basis of morphological, chemotaxonomic, metabolic and phylogenetic differences from other species of Promicromonosporaceae, a new genus and species, Myceligenerans xiligouense gen. nov., sp. nov., is proposed. The type strain is XLG9A10.2T (=DSM 15700T=CGMCC 1.3458T.)

Reclassification of Promicromonospora pachnodae Cazemier et al. 2004 as Xylanimicrobium pachnodae gen. nov., comb. nov.

The recently described facultatively anaerobic Promicromonospora pachnodae is phylogenetically only moderately related to authentic members of Promicromonospora. P. pachnodae is closely related to Xylanibacterium ulmi and slightly less closely related to Xylanimonas cellulosilytica and Isoptericola variabilis (basonym Cellulosimicrobium variabile). Members of the different genera of Promicromonosporaceae have similar chemotaxonomic properties; they share the same peptidoglycan type (A4alpha) and have similar profiles of polar lipids, menaquinones, fatty acids and whole cell sugars. However, they differ from each other in the detailed amino acid composition of peptidoglycan, a taxonomically significant character that has previously been used in the delineation of actinobacterial genera. Recognized Promicromonospora species and Xylanibacterium ulmi exhibit the L-Lys-L-Ala-D-Glu type, Xylanimonas cellulosilytica and I. variabilis show the L-Lys-D-Asp type, whereas P. pachnodae has the L-Lys-L-Ser-D-Glu type. This property, together with the distinct phylogenetic position of Promicromonospora pachnodae, suggests a novel genus for the xylanolytic organism Xylanimicrobium pachnodae (Cazemier et al. 2004) gen. nov., comb. nov.

Arthrobacter psychrophenolicus sp. nov., isolated from an alpine ice cave.

On the basis of phenotypic, genotypic and chemotaxonomic characteristics, a novel species belonging to the genus Arthrobacter is described. A facultatively psychrophilic bacterium, strain AG31(T), was isolated from an alpine ice cave. The aerobic, Gram-positive, non-spore-forming, non-motile strain exhibited a rod-coccus growth cycle and produced a yellow pigment. Good growth and phenol biodegradation occurred at a temperature range of 1-25 degrees C. Up to 10 mM phenol was utilized as a sole carbon source. Glucose was not assimilated. Analysis of the 16S rRNA gene revealed that strain AG31(T) represents a distinct lineage within the genus Arthrobacter, being most closely related to Arthrobacter sulfureus. The level of DNA-DNA relatedness to the type strain of A. sulfureus was 29.9 %. Anteiso-C(15 : 0) was the predominant fatty acid (72 %). Strain AG31(T) exhibited A4alpha l-lys-l-Glu-type peptidoglycan and contained glucose as the only cell-wall sugar. MK-10 was the predominant menaquinone, and the polar lipid pattern consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unidentified glycolipid. Strain AG31(T) (=DSM 15454(T)=LMG 21914(T)) is assigned as the type strain of a novel Arthrobacter species, Arthrobacter psychrophenolicus sp. nov.

Brevibacterium picturae sp. nov., isolated from a damaged mural painting at the Saint-Catherine chapel (Castle Herberstein, Austria).

Three strains showing highly similar (GTG)5-PCR patterns were isolated from a heavily damaged mural painting at the Saint-Catherine chapel (Castle Herberstein, Austria). On the basis of 16S rRNA gene sequence similarity, the strains were attributed to Brevibacterium, with Brevibacterium casei (96.7 %), Brevibacterium iodinum (96.7 %) and Brevibacterium linens (96.6 %) as the closest related species. Chemotaxonomic data [peptidoglycan contains meso-diaminopimelic acid; mycolic acids absent; MK-8(H2) as the major menaquinone; polar lipids phosphatidylglycerol and diphosphatidylglycerol present; anteiso-C(15 : 0) and anteiso-C(17 : 0) as major fatty acids] supported the affiliation of the strains to the genus Brevibacterium. Additional physiological and biochemical tests confirmed the taxonomic position of the strains and allowed phenotypic differentiation from Brevibacterium species with validly published names. The isolates from the mural painting, therefore, represent a novel species, for which the name Brevibacterium picturae sp. nov. is proposed, with LMG 22061T (= DSM 16132T) as the type strain.
