Degrading Bacterium

A yellow-pigmented, Gram-negative, aerobic, non-motile, non-spore-forming, rod-shaped-bacterium, LE124T, was isolated from a hexachlorocyclohexane (HCH) dumpsite located in Lucknow, India. The type strain LE124T grew well with hexachlorocyclohexane as a sole carbon source, degrading it within 24 h of incubation. Phylogenetic analysis of strain LE124T showed highest 16S rRNA gene sequence similarity to Novosphingobium barchaimii LL02T (98.5 %), Novosphingobium panipatense SM16T (98.1 %), Novosphingobium soli CC-TPE-1T (97.9 %), Novosphingobium naphthalenivorans TUT562T (97.6 %), Novosphingobium mathurense SM117T (97.5 %) and Novosphingobium resinovorum NCIMB 8767T (97.5 %) and lower sequence similarity (<97 %) to all other members of the genus Novosphingobium . The DNA–DNA relatedness between strain LE124T and N. barchaimii LL02T and other related type strains was found to vary from 15 % to 45 % confirming that it represents a novel species. The genomic DNA G+C content of strain LE124T was 60.7 mol%. The predominant fatty acids were summed feature 8 (C18 : 1ω7c, 49.1 %), summed feature 3 (C16 : 1ω7c/C16 : 1ω6c, 19.9 %), C16 : 0 (6.7 %), C17 : 1ω6c (4.9 %) and a few hydroxyl fatty acids, C14 : 0 2-OH (9.4 %) and C16 : 0 2-OH (2.1 %). Polar lipids consisted mainly of phosphatidyldimethylethanolamine, phosphatidylcholine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, sphingoglycolipid and some unidentified lipids. The major respiratory quinone was ubiquinone Q-10. Spermidine was the major polyamine observed. Phylogenetic analysis, DNA–DNA hybridization, chemotaxonomic and phenotypic analysis support the conclusion that strain LE124T represents a novel species within the genus Novosphingobium for which we propose the name Novosphingbium lindaniclasticum sp. nov. The type strain is LE124T ( = CCM 7976T = DSM 25409T).

Four unknown strains belonging to the genus Arthrobacter were isolated from plateau wildlife on the Qinghai–Tibet Plateau of PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four isolates were separated into two clusters. Cluster I (strains 785T and 208) had the greatest 16S rRNA gene sequence similarity to Arthrobacter citreus (98.6 and 98.7 %, respectively), Arthrobacter luteolus (98.0 and 98.1%, respectively), Arthrobacter gandavensis (97.9 and 98.0 %, respectively) and Arthrobacter koreensis (97.6 and 97.7 %, respectively). Likewise, cluster II (strains J391T and J915) had the highest sequence similarity to Arthrobacter ruber (98.6 and 98.3 %, respectively) and Arthrobacter agilis (98.1 and 97.9  %, respectively). Average nucleotide identity and the digital DNA–DNA hybridization values illustrated that the two type strains, 785T and J391T, represented two separate novel species that are distinct from all currently recognized species in the genus Arthrobacter . These strains had DNA G+C contents of 66.0–66.1 mol% (cluster I) and 68.0 mol% (cluster II). The chemotaxonomic properties of strains 785T and J391T were in line with those of the genus Arthrobacter : anteiso-C15:0 (79.3 and 40.8 %, respectively) as the major cellular fatty acid, MK-8(H2) (65.8 %) or MK-9(H2) (75.6 %) as the predominant respiratory quinone, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycolipids and phospholipid, and A3α or A4α as the cell wall peptidoglycan type. On the basis of our results, two novel species in the genus Arthrobacter are proposed, namely Arthrobacter yangruifuii sp. nov. (type strain, 785T=CGMCC 1.16725T=GDMCC 1.1592T=JCM 33491T) and Arthrobacter zhaoguopingii sp. nov. (type strain, J391T=CGMCC 1.17382T=GDMCC 1.1667T=JCM 33841T).

A non-motile, yellow–orange-pigmented bacterial strain, designated HME6664T, was isolated from Lake Soyang, Republic of Korea. The major fatty acids of strain HME6664T were summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 44.7 %) and iso-C15 : 0 (20.2 %). The DNA G+C content was 40.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME6664T formed a lineage within the genus Mucilaginibacter . Strain HME6664T was closely related to Mucilaginibacter ximonensis (96.7 %), Mucilaginibacter dorajii (96.5 %) and Mucilaginibacter lappiensis (96.3 %). On the basis of the evidence presented in this study, strain HME6664T represents a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter soyangensis sp. nov., is proposed. The type strain is HME6664T ( = KCTC 23261T = CECT 7824T).

A polyphasic analysis was undertaken of seven independent isolates of Gram-negative cocci collected from pathological clinical samples from New York, Louisiana, Florida and Illinois and healthy subgingival plaque from a patient in Virginia, USA. The 16S rRNA gene sequence similarity among these isolates was 99.7–100 %, and the closest species with a validly published name was Neisseria lactamica (96.9 % similarity to the type strain). DNA–DNA hybridization confirmed that these isolates are of the same species and are distinct from their nearest phylogenetic neighbour, N. lactamica . Phylogenetic analysis of 16S and 23S rRNA gene sequences indicated that the novel species belongs in the genus Neisseria . The predominant cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C18 : 1ω7c. The cellular fatty acid profile, together with other phenotypic characters, further supports the inclusion of the novel species in the genus Neisseria . The name Neisseria oralis sp. nov. (type strain 6332T  = DSM 25276T  = LMG 26725T) is proposed.

Two strains, 8-4-E12T and 8-4-E13T, were isolated from a biowaste composting reactor. Based on 16S rRNA gene sequences, both strains belong to the genus Bacillus . Strain 8-4-E12T was most closely related to the type strains of Bacillus shackletonii , B. acidicola , B. sporothermodurans and B. oleronius (96.4, 96.3, 96.0 and 95.6 % 16S rRNA gene similarity, respectively), whereas strain 8-4-E13T was most closely related to the type strain of Bacillus humi (96.5 % sequence similarity). Strains 8-4-E12T and 8-4-E13T shared 94 % 16S rRNA gene sequence similarity. The fatty acid profile of strain 8-4-E12T was dominated by saturated iso- and anteiso-branched fatty acids (iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0), and also contained considerable amounts of C16 : 0. The fatty acid profile of strain 8-4-E13T showed a predominance of iso-C15 : 0 (65 %), with smaller amounts of other saturated branched-chain fatty acids along with an unsaturated alcohol. Both strains contained diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as major polar lipids. Additionally, strain 8-4-E12T contained an unknown lipid and strain 8-4-E13T two unknown (amino-)phospholipids. The diagnostic diamino acid found in the cell-wall peptidoglycan of 8-4-E12T and 8-4-E13T was meso-diaminopimelic acid. The predominant menaquinone was MK-7. The results of physiological and biochemical tests also allowed phenotypic differentiation of the two strains from each other and from related Bacillus species. On the basis of their phylogenetic, phenotypic and chemotaxonomic properties, strains 8-4-E12T and 8-4-E13T represent novel species of the genus Bacillus , for which the names Bacillus pervagus sp. nov. (type strain 8-4-E12T = DSM 23947T = LMG 27601T) and Bacillus andreesenii sp. nov. (type strain 8-4-E13T = DSM 23948T = LMG 27602T) are proposed.

A moderately halophilic bacterial strain, designated XH204T, was isolated from deep-sea sediment core (45° 58′ S 163° 11′ W) of the South Pacific Gyre during the Integrated Ocean Drilling Program Expedition 329. The strain was Gram-stain-positive, rod-shaped, motile by peritrichous flagella and produced ellipsoidal endospores subterminally positioned within swollen sporangia. Growth of strain XH204T occurred at 15–42 °C (optimum 37 °C), in the presence of 0–14 % (w/v) NaCl (optimum 4 %) and at pH 7.0–10.0 (optimum pH 8.0). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain XH204T belonged to the genus Oceanobacillus and showed the highest sequence similarity to Oceanobacillus profundus CL-MP28T (95.6 %); strain XH204T exhibited 93.4 % 16S rRNA gene sequence similarity to the type strain of the type species of the genus Oceanobacillus , Oceanobacillus iheyensis HTE831T. The dominant fatty acids of strain XH204T were anteiso-C15 : 0, iso-C14 : 0 and iso-C16 : 0. The cell wall of strain XH204T contained meso-diaminopimelic acid as the diagnostic diamino acid, and ribose, glucose and galactose as the major whole-cell sugars. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. Menaquinone-7 (MK-7) was the only isoprenoid quinone and the DNA G+C content was 38.8 mol%. Based on the phenotypic, chemotaxonomic and phylogenetic analysis, strain XH204T represents a novel species of the genus Oceanobacillus , for which the name Oceanobacillus pacificus sp. nov. is proposed. The type strain is XH204T ( = DSM 25873T = JCM 18381T).

Two novel Gram-staining-negative, aerobic, cocci-shaped, non-motile, non-spore forming, pink-pigmented bacteria designated strains T6T and T18T, were isolated from a biocrust (biological soil crust) sample from the vicinity of the Tabernas Desert (Spain). Both strains were catalase-positive and oxidase-negative, and grew under mesophilic, neutrophilic and non-halophilic conditions. According to the 16S rRNA gene sequences, strains T6T and T18T showed similarities with Belnapia rosea CGMCC 1.10758T and Belnapia moabensis CP2CT (98.11 and 98.55% gene sequence similarity, respectively). The DNA G+C content was 69.80 and 68.96% for strains T6T and T18T, respectively; the average nucleotide identity by blast (ANIb) and digital DNA–DNA hybridization (dDDH) values confirmed their adscription to two novel species within the genus Belnapia . The predominant fatty acids were summed feature 8 (C18 : 1ω7c/C18 : 1ω6c), C16 : 0, C18 : 1 2-OH and summed feature 3 (C16 : 1ω7c/C16 : 1ω6c). According to he results of the polyphasic study, strains T6T and T18T represent two novel species in the genus Belnapia (which currently includes only three species), for which names Belnapia mucosa sp. nov. (type strain T6T = CECT 30228T=DSM 112073T) and Belnapia arida sp. nov. (type strain T18T=CECT 30229T=DSM 112074T) are proposed, respectively.

As part of a study investigating the microbiome of bee hives and honey, two novel strains (TMW 2.1880T and TMW 2.1889T) of acetic acid bacteria were isolated and subsequently taxonomically characterized by a polyphasic approach, which revealed that they cannot be assigned to known species. The isolates are Gram-stain-negative, aerobic, pellicle-forming, catalase-positive and oxidase-negative. Cells of TMW 2.1880T are non-motile, thin/short rods, and cells of TMW 2.1889T are motile and occur as rods and long filaments. Morphological, physiological and phylogenetic analyses revealed a distinct lineage within the genus Bombella . Strain TMW 2.1880T is most closely related to the type strain of Bombella intestini with a 16S rRNA gene sequence similarity of 99.5 %, and ANIb and in silico DDH values of 94.16 and 56.3 %, respectively. The genome of TMW 2.1880T has a size of 1.98 Mb and a G+C content of 55.3 mol%. Strain TMW 2.1889T is most closely related to the type strain of Bombella apis with a 16S rRNA gene sequence similarity of 99.5 %, and ANIb and in silico DDH values of 85.12 and 29.5 %, respectively. The genome of TMW 2.1889T has a size of 2.07 Mb and a G+C content of 60.4 mol%. Ubiquinone analysis revealed that both strains contained Q-10 as the main respiratory quinone. Major fatty acids for both strains were C16 : 0, C19 : 0 cyclo ω8c and summed feature 8, respectively, and additionally C14 : 0 2-OH only for TMW 2.1880T and C14 : 0 only for TMW 2.1889T. Based on polyphasic evidence, the two isolates from honeycombs of Apis mellifera represent two novel species of the genus Bombella , for which the names Bombella favorum sp. nov and Bombella mellum sp. nov. are proposed. The designated respective type strains are TMW 2.1880T (=LMG 31882T=CECT 30114T) and TMW 2.1889T (=LMG 31883T=CECT 30113T).

Two facultatively anaerobic mesophilic bacteria, strains MEBiC 07026T and MEBiC 08903T, were isolated from two different tidal flat sediments and both strains showed approximately 92.2 % 16S rRNA gene sequence similarity with [Cytophaga] fermentans DSM 9555T. 16S rRNA gene sequence similarity between the two new isolates was 97.5 % but levels of DNA–DNA relatedness between the two were 31.3–31.8 %. Phylogenetic analysis revealed that the two isolates and [Cytophaga] fermentans DSM 9555T were affiliated with the family Marinilabiliaceae in the class Bacteroidia . The dominant fatty acids of strains MEBiC 07026T, MEBiC 08903T and [Cytophaga] fermentans DSM 9555T were branched-type or hydroxylated C15 : 0, but [Cytophaga] fermentans DSM 9555T contained a higher proportion of anteiso-branched fatty acids. The two new isolates contained a markedly higher proportion of monounsaturated fatty acids than other members of the family Marinilabiliaceae . The major respiratory quinone of the strains was MK-7. Strains MEBiC07026T and MEBiC08903T utilized a wide range of carboxylic acids whereas [Cytophaga] fermentans DSM 9555T utilized carbohydrates rather than carboxylic acids. The DNA G+C content of the novel strains was about 44 mol% but that of [Cytophaga] fermentans DSM 9555T revealed from the genome sequence was 37.6 mol%. Based on evidence from this polyphasic taxonomic study, a novel genus, Carboxylicivirga gen. nov., is proposed in the family Marinilabiliaceae with two novel species, Carboxylicivirga mesophila sp. nov. with type strain MEBiC 07026T ( = KCCM 42978T = JCM 18290T) and Carboxylicivirga taeanensis sp. nov. with type strain MEBiC 08903T ( = KCCM 43024T = JCM 19490T). Additionally, [Cytophaga] fermentans DSM 9555T ( = ATCC 19072T) is reclassified as Saccharicrinis fermentans gen. nov., comb. nov.

A strain of thermotolerant actinomycete, designated YIM 75948T, was isolated from a soil sample in Yunnan province, China. The strain grew at 25–55 °C (optimum 37 °C). The substrate mycelium and aerial mycelium produced on Czapek’s agar were both pale yellow to white. The diagnostic diamino acid of the cell-wall peptidoglycan was meso-diaminopimelic acid, and the whole-cell sugars were mannose, ribose, glucose, galactose and arabinose. The major fatty acids were iso-C15 : 0, iso-C16 : 0 and C16 : 0 and the predominant respiratory quinone was MK-9(H4). The polar lipids consisted of phosphatidylethanolamine, phosphatidylethanolamine with hydroxy fatty acids, diphosphatidylglycerol, phosphatidylinositol and two unidentified phospholipids. The genomic DNA G+C content was 73.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YIM 75948T belonged in the genus Actinokineospora and that its closest relative among recognized species was Actinokineospora fastidiosa DSM 43855T (97.6 % sequence similarity). The mean level of DNA–DNA relatedness between the novel strain and A. fastidiosa DSM 43855T was, however, only 47.8 %. Based on the phenotypic, chemotaxonomic and phylogenetic data and the results of the DNA–DNA hybridizations, strain YIM 75948T represents a novel species of the genus Actinokineospora for which the name Actinokineospora soli sp. nov. is proposed. The type strain is YIM 75948T ( = JCM 17695T = DSM 45613T). The description of the genus Actinokineospora is emended to reflect the fact that the genomic DNA G+C contents of A. fastidiosa DSM 43855T and the type strain of Actinokineospora soli sp. nov. recorded in the present study fell above the range given in previous descriptions of this genus.
