Beverage Industry

A facultatively anaerobic, alkaliphilic, Gram-stain-positive, rod-shaped bacterium, designated strain 12/1T, isolated from alkaline wastewater drained sludge of a beverage industry facility located near New Delhi, India, was subjected to a polyphasic taxonomic study. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain 12/1T belonged to the genus Exiguobacterium and was most closely related to Exiguobacterium aurantiacum DSM 6208T (99.46 %), E. aquaticum IMTB-3094T (99.18 %), E. mexicanum 8NT (99.06 %), E. profundum 10CT (98.17 %), E. aestuarii TF-16T (98.1 %) and E. marinum TF-80T (98.03 %). The DNA G+C content of strain 12/1T was 55.6 mol%, major respiratory isoprenoid quinone was MK-7, major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine and the cell-wall peptidoglycan was of the A3α l-Lys–Gly type, characteristics consistent with its affiliation to the genus Exiguobacterium . Strain 12/1T showed levels of DNA–DNA hybridization of less than 70 % with the closely related species of the genus Exiguobacterium . Overall, the phenotypic, chemotaxonomic and phylogenetic data presented in this study suggest that strain 12/1T represents a novel species of the genus Exiguobacterium , for which the name Exiguobacterium alkaliphilum sp. nov. is proposed. The type strain is 12/1T ( = CCM 8459T = DSM 21148T).

Diamino Acid

A novel Gram-stain-positive actinobacterium, designated PS-14-7T, was isolated from the rhizosphere of a mangrove on Pramuka Island, Indonesia, and its taxonomic position was investigated using a polyphasic approach. The peptidoglycan type of strain PS-14-7T was A4α and lysine was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-8(H4) and the major fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The DNA G+C content was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain PS-14-7T was closely related to Serinibacter salmoneus Kis4-28T (99.6 %). However, DNA–DNA hybridization and phenotypic characteristics revealed that strain PS-14-7T differed from Serinibacter salmoneus . Therefore, strain PS-14-7T represents a novel species of the genus Serinibacter , for which the name Serinibacter tropicus sp. nov. is proposed. The type strain is PS-14-7T ( = NBRC 110108T = InaCC A 515T). An emended description of the genus Serinibacter is also proposed.

Taxonomic Description

Strain ATCC 31180T was isolated from soil collected in Hyde Park, Massachusetts (USA), and found to produce the polyether antibiotic lasalocid. The name ‘Streptomyces lasaliensis’ has been in common use since 1974, without a recognized taxonomic description. The most closely related type cultures determined by rRNA gene sequence similarity were Streptomyces longwoodensis DSM 41677T (100 %) and Streptomyces galbus DSM 40089T (100 %). OrthoANI values with S. longwoodensis and S. galbus were 95.50 and 94.41 %, respectively. Chemotaxonomic characteristics supported inclusion within the genus Streptomyces . The cell wall peptidoglycan contained ll-diaminopimelic acid, and the major whole-cell sugars were glucose and ribose. Polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylglycerol, one unidentified lipid and one unidentified glycolipid. The major menaquinones detected were MK9(H4), MK9(H6) and MK9(H8). The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0, iso-C15 : 0 and anteiso-C17 : 1. Its DNA had a G+C content of 72.6 %. Differentiation of ATCC 31180T from the closely related species was evident from digital DNA–DNA hybridization values of 61.80 and 56.90 % for S. longwoodensis and S. galbus respectively. Significant differences were seen in the polyphasic phenotypic analyses. ATCC 31180T produced lasalocid, grew from 10 to 45 °C, pH4-8 and in the presence of 0–10 % NaCl, 0.01 % NaN3 and 1 % phenol. Melanin was produced; H2S and indole were not. Nitrate was not reduced. Spore chains were retinaculum-apertum and spore surfaces were smooth. Spore colour, mycelia colour and soluble pigment production were medium-dependent. The proposed name is Streptomyces lasalocidi sp. nov.; the type strain being ATCC 31180T (=NRRL 3382T=DSM 46487T).

A novel actinomycete, designated Z4T, was isolated from soil in Yaan, Sichuan Province, south China. The taxonomic status of this strain was established using a polyphasic approach. The morphological and chemotaxonomic characteristics of the organism are typical of the members of the genus Streptomyces . Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that strain Z4T belonged to the genus Streptomyces , branching off next to Streptomyces durhamensis ATCC 23194T (98.7 %), Streptomyces puniciscabiei KACC 20253T (98.7 %) and Streptomyces filipinensis ATCC 23905T (98.6 %). However, DNA–DNA hybridization studies and phenotypic differences between strain Z4T and closely related species of the genus Streptomyces suggested that strain Z4T represented a different genomic species. It is therefore proposed that Z4T ( = CGMCC 4.7035T = KCTC 29111T) represents the type strain of a novel species of the genus Streptomyces , for which the name Streptomyces yaanensis sp. nov. is proposed.

Cells of bacterial strains 4 G-K06T and 4MSK11T, isolated from soil samples collected from monsoon evergreen broad-leaved forest of the Dinghushan Mountain (112° 31′ E 23° 10′ N), Guangdong Province, PR China, were Gram-stain-negative, aerobic, non-spore-forming, non-motile and rod-shaped. Strain 4 G-K06T grew at 10–37 °C, pH 3.5–7.5 and 0–3.5 % (w/v) NaCl; while 4MSK11T grew at 4–42 °C, pH 3.5–7.5 and 0–2.5 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed strain 4 G-K06T formed a clade with Dyella flagellata 4 M-K16T, Dyella acidisoli 4M-Z03T, Dyella humi DHG40T and Dyella nitratireducens DHG59T, while strain 4MSK11T formed a clade with Dyella caseinilytica DHOB09T and Dyella mobilis DHON07T, both within the genus Dyella . The result of the partial atpD, gyrB and lepA gene sequence analysis supported the conclusion based on 16S rRNA gene sequence analysis, which showed that these two strains represent two novel species of Dyella . The average nucleotide identity and digital DNA–DNA hybridization value for the whole genomes were 75.0–79.0 and 20.3–22.6 % between strains 4 G-K06T, 4MSK11T and those described Dyella species with genome sequences; while the DNA–DNA hybridization rates between strains 4 G-K06T, 4MSK11T and closely related Dyella species (without genome sequence) were 29.5–41.8 %. The major cellular fatty acids of these two strains were iso-C15 : 0, iso-C16 : 0 and iso-C17 : 1 ω9c, while the major polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several unidentified phospholipids and aminophospholipids. The only ubiquinone of these two strains was ubiquinone-8. The DNA G+C contents of 4 G-K06T and 4MSK11T were 60.4 and 61.3 mol%, respectively. On the basis of the evidence presented here, strains 4 G-K06T and 4MSK11T represent two novel species of the genus Dyella , for which the names Dyella monticola sp. nov. (type strain 4 G-K06T=LMG 30268T=GDMCC 1.1188T) and Dyella psychrodurans sp. nov. (type strain 4MSK11T=KCTC 62280T=GDMCC 1.1185T) are proposed.

Moderately Halophilic Bacterium

An aerobic, Gram-stain-positive, endospore-forming, rod-shaped and moderately halophilic strain SKP4-6T, was isolated from shrimp paste (Ka-pi) collected from Samut Sakhon Province, Thailand. Phylogenetic analysis revealed that strain SKP4-6T belonged to the genus Halobacillus and was most closely related to Halobacillus salinus JCM 11546T (98.6 %), Halobacillus locisalis KCTC 3788T (98.6 %) and Halobacillus yeomjeoni KCTC 3957T (98.6 %) based on 16S rRNA gene sequence similarity. The digital DNA–DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strain SKP4-6T and its related species were 18.2–19.3 % and 69.84–84.51 %, respectively, which were lower than the threshold recommended for species delineation. The strain grew optimally at 30–40 °C, at pH 7.0 and with 10–15 % (w/v) NaCl. It contained l-Orn–d-Asp in the cell wall peptidoglycan. The DNA G+C content was 44.8 mol%. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The predominant isoprenoid quinone was MK-7. Phosphatidylglycerol and diphosphatidylglycerol were present as major polar lipids. Based on this polyphasic approach, digital DNA–DNA relatedness and ANI values, strain SKP4-6T represents a novel species of the genus Halobacillus , for which the name Halobacillus fulvus sp. nov. is proposed. The type strain is SKP4-6T (=JCM 32624T=TISTR 2595T).

A Gram-stain-negative bacterium, designated strain Marseille-Q3039T, was isolated from subgingival dental plaque of a woman with gingivitis in Marseille, France. Strain Marseille-Q3039T was found to be an anaerobic, motile and spore-forming crescent-shaped bacterium that grew at 25–41.5 °C (optimum, 37 °C), pH 5.5–8.5 (optimum, pH 7.5) and salinity of 5.0 g l−1 NaCl. The results of 16S rRNA gene sequence analysis revealed that strain Marseille-Q3039T was closely related to Selenomonas infelix ATCC 43532T (98.42 % similarity), Selenomonas dianae ATCC 43527T (97.25 %) and Centipedia periodontii DSM 2778T (97.19 %). The orthologous average nucleotide identity and digital DNA–DNA hybridization relatedness between strain Q3039T and its closest phylogenetic neighbours were respectively 84.57 and 28.2 % for S. infelix ATCC 43532T and 83.93 and 27.2 % for C. periodontii DSM 2778T. The major fatty acids were identified as C13 : 0 (27.7 %), C15 : 0 (24.4 %) and specific C13 : 0 3-OH (12.3 %). Genome sequencing revealed a genome size of 2 351 779 bp and a G+C content of 57.2 mol%. On the basis of the results from phenotypic, chemotaxonomic, genomic and phylogenetic analyses and data, we concluded that strain Marseille-Q3039T represents a novel species of the genus Selenomonas , for which the name Selenomonas timonae sp. nov. is proposed (=CSUR Q3039=CECT 30128).

Phospholipid Profile

A Gram-reaction-positive aerobic actinomycete, designated strain MN08-A0118T, which produced short chains of non-motile spores on the tips of long sporophores and formed yellow–brown colonies with branched substrate mycelium, was studied in detail to determine its taxonomic position. On the basis of 16S rRNA gene sequence analyses, strain MN08-A0118T was grouped into the genus Herbidospora , being most closely related to Streptosporangium claviforme (98.2 %), Herbidospora osyris (98.2 %), Herbidospora daliensis (98.2 %), Herbidospora cretacea (97.9 %) and Herbidospora yilanensis (97.4 %). Chemotaxonomic data supported allocation of the strain to the genus Herbidospora . MK-10(H4) was the predominant menaquinone with minor amounts of MK-10(H6), MK-10(H2) and MK-9(H4); the fatty acid profile contained major amounts of iso-C16 : 0, C17 : 0 10-methyl, iso-C14 : 0 and iso-C16 : 0 2-OH; the phospholipid profile contained phosphatidylethanolamine, phosphatidylmethylethanolamine and glucosamine-containing phospholipids; and the whole-cell sugars included ribose, glucose, galactose, madurose and rhamnose (trace). The phylogenetic data, phenotypic and genotypic properties and DNA–DNA hybridization differentiated this strain from its closely related strains, S. claviforme (35–54 % DNA–DNA relatedness), H. osyris (39–51 %), H. daliensis (3–16 %), H. cretacea (34–39 %) and H. yilanensis (34–42 %). Thus, MN08-A0118T represents a novel species of the genus Herbidospora , for which the name Herbidospora mongoliensis sp. nov. is proposed, with MN08-A0118T ( = NBRC 105882T  = VTCC D9-22T) as the type strain. In addition, DNA–DNA hybridization results showed that S. claviforme and H. osyris are synonyms of H. cretacea .

Two strains (JA643T and JA755) of Gram-stain-negative, facultatively anaerobic phototrophic, bacteria capable of growth at low temperatures (10–15 °C) were isolated from freshwater streams from different geographical regions of India. Both strains contain bacteriochlorophyll a and carotenoids of the spirilloxanthin series. Phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid (PL), unidentified amino lipids (AL1–AL6, AL9) and an unidentified lipid (L1) were the polar lipids present in both strains. The major cellular fatty acid was C18 : 1ω7c (76–79 % of the total). Bacteriohopane derivatives (BHD1,2), unidentified hopanoids (UH1–5), diplopterol (DPL) and diploptene (DPE) were the major hopanoids of both strains. The DNA G+C content was 64.2–64.5 mol%. 16S rRNA gene sequence-based phylogenetic analysis showed that both strains are closely related to the genus Rhodomicrobium and clustered with Rhodomicrobium vannielii DSM 162T (99 % sequence similarity). However, both strains exhibited only 46.1 % DNA–DNA hybridization with R. vannielii DSM 162T. Strains JA643T and JA755 shared >99 % 16S rRNA gene sequence similarity and were >85 % related on the basis of DNA–DNA hybridization; they are therefore considered to represent a novel species in the genus Rhodomicrobium , for which the name Rhodomicrobium udaipurense sp. nov. is proposed. The type strain is JA643T ( = KCTC 15219T = NBRC 109057T).

A novel Gram-stain-negative, aerobic, heterotrophic, stalked and capsulated bacterium with potential denitrification ability, designated strain TAR-002T, was isolated from deep seafloor sediment in Japan. Colonies lacked lustre, and were viscous and translucent white. The ranges of temperature, pH and salt concentration for growth were 8–30 °C, pH 6.0–10.0 and 1–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain TAR-002T belongs to the genus Brevundimonas of the class Alphaproteobacteria . Levels of similarity between the 16S rRNA gene sequence of strain TAR-002T and those of the type strains of species of the genus Brevundimonas were 93.5–98.9 %; the most closely related species was Brevundimonas basaltis . In DNA–DNA hybridization assays between strain TAR-002T and its phylogenetic neighbours, Brevundimonas lenta DS-18T, B. basaltis J22T, Brevundimonas subvibrioides ATCC 15264T and Brevundimonas alba DSM 4736T, mean hybridization levels were 6.4–27.7 %. The G+C content of strain TAR-002T was 70.3 mol%. Q-10 was the major respiratory isoprenoid quinone. The major fatty acids were C18 : 1ω7c and C16 : 0, and the presence of 1,2-di-O-acyl-3-O-[d-glucopyranosyl-(1→4)-α-d-glucopyranuronosyl]glycerol (DGL) indicates the affiliation of strain TAR-002T with the genus Brevundimonas . On the basis of biological characteristics and 16S rRNA gene sequence comparisons, strain TAR-002T is considered to represent a novel species of the genus Brevundimonas , for which the name Brevundimonas denitrificans sp. nov. is proposed; the type strain is TAR-002T ( = NBRC 110107T = CECT 8537T).
