Novel Genus And Species

An actinobacterial strain containing demethylmenaquinone DMK-9(H4) as the diagnostic isoprenoid quinone was isolated from a tidal flat sediment sample, from South Korea. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JC2054T represents a distinct phyletic line within the suborder Micrococcineae of the order Actinomycetales. The closest phylogenetic neighbour was Cellulomonas fermentans, with 94.7 % 16S rRNA gene sequence similarity. The novel isolate was strictly aerobic and slightly halophilic, with optimum growth occurring in 2–4 % (w/v) NaCl. Cells were non-motile, non-sporulating and rod-shaped. The peptidoglycan type was of the A-type of cross-linkage. l-ornithine was the diamino acid and d-glutamate represented the N-terminus of the interpeptide bridge. The predominant fatty acids were anteiso-branched and straight-chain fatty acids. The major polar lipids were phosphatidylinositol, diphosphatidylglycerol and an unknown phospholipid. The menaquinone composition of C. fermentans was determined to be MK-10(H4), MK-9(H4) and MK-8(H4) in the ratio 56 : 2 : 1. On the basis of the polyphasic evidence presented in this study, it is proposed that strain JC2054T should be classified as representing a novel genus and species of the suborder Micrococcineae, with the name Demequina aestuarii gen. nov., sp. nov. The type strain is JC2054T (=IMSNU 14027T=KCTC 9919T=JCM 12123T). In addition, it was clear from the phylogenetic analysis and chemotaxonomic data that C. fermentans does not belong to the genus Cellulomonas or any other recognized genera. Therefore, C. fermentans should be reclassified as representing a novel genus, for which the name Actinotalea fermentans gen. nov., comb. nov. is proposed, with strain DSM 3133T (=ATCC 43279T=CFBP 4259T=CIP 103003T=NBRC 15517T=JCM 9966T=LMG 16154T) as the type strain.

A Gram-negative, chemoheterotrophic, facultatively anaerobic coccus, designated IMCC1545T, was isolated from the digestive tract of a marine clamworm, Periserrula leucophryna, inhabiting a tidal flat of the Yellow Sea. Cells of strain IMCC1545T are non-motile, dividing by binary fission. The predominant fatty acids are anteiso-C15 : 0 and C18 : 0. The respiratory quinone is menaquinone-7 and the DNA G+C content is 52.1 mol%. Phylogenetic analyses based on 16S rRNA gene sequences using three treeing algorithms revealed that the strain formed a novel genus-level lineage within the phylum ‘Verrucomicrobia’. The most closely related named organisms to strain IMCC1545T are ‘Fucophilus fucoidanolyticus’ SI-1234 (86.5 % 16S rRNA gene sequence similarity), Alterococcus agarolyticus ADT3T (81.8 %) and Opitutus terrae PB90-1T (80.3 %), which belong to subdivision 4 of the ‘Verrucomicrobia’. Subdivision 4 of the ‘Verrucomicrobia’ (here named Opitutae classis nov.) was divided into two clades, a clade containing strain IMCC1545T and a clade containing Opitutus terrae. From the taxonomic data obtained in this study, it is proposed that the new marine isolate be placed into a novel genus and species named Puniceicoccus vermicola gen. nov., sp. nov. (the type strain of Puniceicoccus vermicola is IMCC1545T=KCCM 42343T=NBRC 101964T) within Puniceicoccaceae fam. nov and Puniceicoccales ord. nov in the class Opitutae. The family Opitutaceae fam. nov. and order Opitutales ord. nov. are also formally proposed.

Bacterial strains UST030701-097T and UST030701-084T were isolated from a marine sponge in the Bahamas. Both strains were pink-pigmented, Gram-negative, strictly aerobic and chemo-organotrophic. Cells of strain UST030701-097T were short, curved rods with fast-gliding motility, whereas those of strain UST030701-084T were straight rods with a less rapid gliding motion. The two strains had MK-7 as the major respiratory quinone and did not produce flexirubin-type pigments. The DNA G+C contents of strains UST030701-097T and UST030701-084T were 42.5 and 43.7 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the two strains belonged to the family ‘Flexibacteraceae’ of the phylum Bacteroidetes. 16S rRNA gene sequence similarity between strains UST030701-097T and UST030701-084T was 95.0 %; their closest relative was [Marinicola] seohaensis, with 93.3 % and 96.0 % sequence similarity, respectively. Phylogenetic tree topology indicated that the two strains belonged to the same lineage, but were on separate branches. Whilst strain UST030701-084T and [Marinicola] seohaensis were found on one branch, strain UST030701-097T was in another branch that had no species with validly published names. Based on the polyphasic taxonomic data obtained in the present study, we propose that strain UST030701-097T represents a novel genus and that strain UST030701-084T represents a novel species in the phylum Bacteroidetes. The genus Fabibacter gen. nov. is proposed, with strain UST030701-097T (=NRRL B-41220T=JCM 13334T) as the type strain of the type species, Fabibacter halotolerans sp. nov. Strain UST030701-084T (=NRRL B-41219T=JCM 13337T) is proposed as the type strain of Roseivirga spongicola sp. nov. In an earlier study, it was suggested that the genus Marinicola is a later heterotypic synonym of the genus Roseivirga. However, a formal proposal to reclassify [Marinicola] seohaensis, the only member of the genus Marinicola, has not yet been made. The results of phylogenetic analyses in this study support the reclassification of [Marinicola] seohaensis as Roseivirga seohaensis comb. nov.

Three Gram-negative, motile, mesophilic, aerobic, rod-shaped bacterial strains, designated 2O1T, 1O14 and 1O18, were isolated from Indonesian seawater after enrichment with crude oil and a continuous supply of supplemented seawater. The strains exhibited high n-alkane-degrading activity, which indicated that the strains were important degraders of petroleum aliphatic hydrocarbons in tropical marine environments. Phylogenetic analyses based on 16S rRNA gene sequences of members of the Gammaproteobacteria showed that the isolates formed a coherent and distinct cluster in a stable lineage containing Oceanobacter kriegii IFO 15467T (96.4–96.5 % 16S rRNA gene sequence similarity) and Thalassolituus oleivorans MIL-1T. DNA G +C content was 53.0–53.1 mol%. The major fatty acids were C16 : 0, C16 : 1 ω7 and C18 : 1 ω9 and the hydroxy fatty acids were C12 : 0 3-OH and C10 : 0 3-OH. The polar lipids were phosphatidylglycerol, a ninhydrin-positive phospholipid(s) and glycolipids. The major quinone was Q-9 (97–99 %), which distinguished the isolates from Oceanobacter kriegii NBRC 15467T (Q-8; 91 %). On the basis of phenotypic, genotypic and chemotaxonomic data, including DNA–DNA hybridization, the isolates represent a novel genus and species, for which the name Oleibacter marinus gen. nov., sp. nov. is proposed. The type strain of Oleibacter marinus is 2O1T (=NBRC 105760T =BTCC B-675T).

A Gram-negative, chemoheterotrophic, strictly aerobic, alkaliphilic, rod-shaped marine bacterium, designated HTCC2654T, was isolated from the western Sargasso Sea by using a dilution-to-extinction culturing method. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HTCC2654T belonged to the Roseobacter clade of the order Rhodobacterales. The 16S rRNA gene sequence similarity of the strain with respect to other members of the Roseobacter clade ranged from 90.4 to 95.1 %. In the phylogenetic analyses, the strain formed an independent phyletic line and could not be assigned to any other known genera of the Rhodobacterales. The DNA G+C content of strain HTCC2654T was 61.7 mol% by HPLC and 64.1 mol% from genome sequences. The predominant constituents of the cellular fatty acids were C16 : 0 2-OH (27.3 %), 11-methyl C18 : 1 ω7c (19.6 %) and C18 : 1 ω7c (17.3 %), and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine, which served to differentiate the strain from other members of the Roseobacter clade. On the basis of the taxonomic data obtained in this study, strain HTCC2654T represents a novel genus and species, for which the name Maritimibacter alkaliphilus gen. nov., sp. nov. is proposed. The type strain is HTCC2654T (=KCCM 42376T=NBRC 102057T).

Six new Vibrio-like isolates originating from different species of bleached and healthy corals around Magnetic Island (Australia) were investigated using a polyphasic approach. Phylogenetic analyses based on 16S rRNA, recA and rpoA gene sequences split the isolates in two new groups. Strains LMG 22223T, LMG 22224, LMG 22225, LMG 22226 and LMG 22227 were phylogenetic neighbours of Photobacterium leiognathi LMG 4228T (95·6 % 16S rRNA gene sequence similarity), whereas strain LMG 22228T was related to Enterovibrio norvegicus LMG 19839T (95·5 % 16S rRNA gene sequence similarity). The two new groups can be distinguished from closely related species on the basis of several phenotypic features, including fermentation of d-mannitol, melibiose and sucrose, and utilization of different compounds as carbon sources, arginine dihydrolase activity, nitrate reduction, resistance to the vibriostatic agent O/129 and the presence of fatty acids 15 : 0 iso and 17 : 0 iso. The names Photobacterium rosenbergii sp. nov. (type strain LMG 22223T=CBMAI 622T=CC1T) and Enterovibrio coralii sp. nov. (type strain LMG 22228T=CBMAI 623T=CC17T) are proposed to accommodate these new isolates. The G+C contents of the DNA of the two type strains are respectively 47·6 and 48·2 mol%.

Two strictly aerobic, Gram-negative bacteria, designated strains CL-SP27T and B5-6T, were isolated from the hypersaline water of a solar saltern in Korea and from the surface water of the Sargasso Sea, respectively. The two strains were rod-shaped, non-motile and grew on marine agar 2216 as beige colonies. Phylogenetic analyses of 16S rRNA gene sequences revealed a clear affiliation of the novel strains to the family Rhodobacteraceae. However, the novel strains were only distantly related to members of the Roseobacter clade, forming a distinct lineage. Although the 16S rRNA gene sequence similarity between strains CL-SP27T and B5-6T was very high (99.6 %), DNA–DNA relatedness between the strains was 48.4 %, suggesting that the strains be categorized as two genospecies. Additionally, the two novel strains could be differentiated by DNA G+C contents, fatty acid profiles, carbon source utilization patterns, antibiotic susceptibilities and biochemical characteristics. Based on taxonomic data obtained in this study, strains CL-SP27T and B5-6T represent separate species within a novel genus of the family Rhodobacteraceae, for which the names Maribius salinus gen. nov., sp. nov. (type species) and Maribius pelagius sp. nov. are proposed. The type strains of Maribius salinus and Maribius pelagius are CL-SP27T (=KCCM 42113T=JCM 13037T) and B5-6T (=KCCM 42336T=JCM 14009T), respectively.

A Gram-staining-negative, strictly aerobic bacterium, designated strain G3T, was isolated from a tidal flat of the Taean coast in South Korea. Cells were moderately halotolerant and non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain G3T was observed between 15 and 40 °C (optimum 30 °C) and between pH 5.5 and 9.0 (optimum pH 6.5–7.5). Strain G3T contained Q-8 as the predominant lipoquinone and iso-C15 : 0, iso-C17 : 1ω9c, iso-C16 : 0 and iso-C11 : 0 as the major fatty acids. The G+C content of the genomic DNA was 69.6 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain G3T formed a tight phylogenetic lineage with Luteimonas mephitis B1953/27.1T within the genus Luteimonas and was most closely related to L. mephitis B1953/27.1T with 98.0 % 16S rRNA gene sequence similarity. The DNA–DNA relatedness between strain G3T and L. mephitis B1953/27.1T was 35.2±3.3 %. On the basis of chemotaxonomic data and molecular properties, strain G3T represents a novel species of the genus Luteimonas, for which the name Luteimonas lutimaris sp. nov. is proposed. The type strain is G3T ( = KACC 14929T = JCM 16916T).

Five strains of strictly aerobic, heterotrophic bacteria that form pink–red colonies and are capable of hydrolysing pectin, xylan, laminarin, lichenan and starch were isolated from acidic Sphagnum peat bogs and were designated OB1010T, LCBR1, TPB6011T, TPB6028T and TPO1014T. Cells of these isolates were Gram-negative, non-motile rods that produced an amorphous extracellular polysaccharide-like substance. Old cultures contained spherical bodies of varying sizes, which represent starvation forms. Cells of all five strains were acidophilic and psychrotolerant, capable of growth at pH 3.0–7.5 (optimum pH 3.8–4.5) and at 2–33 °C (optimum 15–22 °C). The major fatty acids were iso-C15 : 0, C16 : 0 and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH). The major menaquinone detected was MK-8. The pigments were carotenoids. The genomic DNA G+C contents were 57.3–59.3 mol%. The five isolates were found to be members of subdivision 1 of the phylum Acidobacteria and displayed 95.3–98.9 % 16S rRNA gene sequence similarity to each other. The closest described relatives to strains OB1010T, LCBR1, TPB6011T, TPB6028T, and TPO1014T were members of the genera Terriglobus (94.6–95.8 % 16S rRNA gene sequence similarity) and Edaphobacter (94.2–95.4 %). Based on differences in cell morphology, phenotypic characteristics and hydrolytic capabilities, we propose a novel genus, Granulicella gen. nov., containing four novel species, Granulicella paludicola sp. nov. with type strain OB1010T (=DSM 22464T =LMG 25275T) and strain LCBR1, Granulicella pectinivorans sp. nov. with type strain TPB6011T (=VKM B-2509T =DSM 21001T), Granulicella rosea sp. nov. with type strain TPO1014T (=DSM 18704T =ATCC BAA-1396T) and Granulicella aggregans sp. nov. with type strain TPB6028T (=LMG 25274T =VKM B-2571T).

A Gram-stain-negative, strictly aerobic and rod-shaped motile bacterium with peritrichous flagella, designated strain LZB041T, was isolated from offshore surface seawater of the East China Sea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain LZB041T formed a lineage within the family ‘ Aurantimonadaceae ’ that was distinct from the most closely related genera Aurantimonas (96.0–96.4 % 16S rRNA gene sequence similarity) and Aureimonas (94.5–96.0 %). Optimal growth occurred in the presence of 1–7 % (w/v) NaCl, at pH 7.0–8.0 and at 28–37 °C. Ubiquinone-10 was the predominant respiratory quinone. The major fatty acids (>10 % of total fatty acids) were C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8) and cyclo-C19 : 0ω8c. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, one unknown aminolipid, one unknown phospholipid and one unknown polar lipid. The DNA G+C content of strain LZB041T was 71.3 mol%. On the basis of polyphasic analysis, strain LZB041T is considered to represent a novel species of a new genus in the class Alphaproteobacteria , for which the name Jiella aquimaris gen. nov., sp. nov. is proposed. The type strain of the type species is LZB041T ( = JCM 30119T = MCCC 1K00255T).

Four aerobic, Gram-stain-positive, rod-shaped bacteria (HY60T, HY54, HY82T and HY89) were isolated from bat faeces of Hipposideros and Rousettus species collected in PR China. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the four novel strains formed two separate but adjacent subclades close to Microbacterium agarici CGMCC 1.12260T (97.6–97.7 % similarity), Microbacterium humi JCM 18706T (97.3–97.5 %) and Microbacterium lindanitolerans JCM 30493T (97.3–97.4 %). The 16S rRNA gene sequence similarity was 98.3 % between strains HY60T and HY82T, and identical within strain pairs HY60T/HY54 and HY82T/HY89. The DNA G+C contents of strains HY60T and HY82T were 61.9 and 63.3 mol%, respectively. The digital DNA–DNA hybridization and average nucleotide identity values between each novel strain and their closest relatives were all below the 70 % and 95–96 % thresholds for species delimitation, respectively. All four novel strains contained anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0 as the main fatty acids, MK-11 and MK-12 as the major respiratory quinones, and diphosphatidylglycerol, phosphatidylglycerol and one unidentified glycolipid as the predominant polar lipids. The cell-wall peptidoglycan was of B type and contained alanine, glutamate, glycine and ornithine. The acyl type of the muramic acid was glycolyl. The whole-cell sugars were rhamnose and ribose. Based on the foregoing polyphasic analyses, it was concluded that the four uncharacterized strains represented two novel species of the genus Microbacterium , for which the names Microbacterium chengjingii sp. nov. [type strain HY60T (=CGMCC 1.17468T=GDMCC 1.1951T=KACC 22102T)] and Microbacterium fandaimingii sp. nov. [type strain HY82T (=CGMCC 1.17469T=GDMCC 1.1949T=KACC 22101T)] are proposed, respectively.
