Poultry Houses

Two Gram-stain-positive, non-motile, non-spore-forming cocci (strains MK-7T and MPA-33T) were isolated from poultry houses. Strain MK-7T was isolated on marine broth agar from coquina, a food supplement for female ducks used in a duck-fattening farm. Strain MPA-33T was isolated from the air of a turkey house on TSA after filter sampling. On the basis of 16S rRNA gene sequence similarity studies, both strains were shown to belong to the genus Jeotgalicoccus; MK-7T was most closely related to Jeotgalicoccus psychrophilus YKJ-115T (99.3 % similarity) and MPA-33T was most closely related to Jeotgalicoccus halotolerans YKJ-101T (98.8 %). The quinone system of MK-7T was composed of equal amounts of menaquinones MK-7 and MK-6 and that of MPA-33T contained 76 % MK-7 and 24 % MK-6. The polar lipid profile of strain MK-7T consisted of the major compounds diphosphatidylglycerol and phosphatidylglycerol and six unidentified lipids present in minor to moderate amounts. In strain MPA-33T, diphosphatidylglycerol was the single predominant lipid, whereas phosphatidylglycerol was detected in moderate amounts. In addition, one unidentified phospholipid and four unidentified lipids were detected. Fatty acid profiles with iso-15 : 0 and anteiso-15 : 0 as major fatty acids supported the affiliation of the strains to the genus Jeotgalicoccus. The results of physiological and biochemical tests as well as DNA–DNA hybridizations allowed clear phenotypic differentiation of strains MK-7T and MPA-33T from the most closely related species. Strains MK-7T and MPA-33T therefore represent novel species, for which the names Jeotgalicoccus coquinae sp. nov. (type strain MK-7T =DSM 22419T =CCM 7682T =CCUG 57956T) and Jeotgalicoccus aerolatus sp. nov. (type strain MPA-33T =DSM 22420T =CCM 7679T =CCUG 57953T) are proposed.

Diamino Acid

A Gram-positive, non-spore-forming actinobacterium (IMT-300T) was isolated from soil amended with humic acid in Malvern, AL, USA. This soil has been used for 50+years for the cultivation of earthworms for use as fish bait. Based on 16S rRNA gene sequence similarity studies, strain IMT-300T was shown to belong to the genus Leucobacter and was closely related to the type strain of ‘Leucobacter margaritiformis’ L1T (97.8%). Similarity to all other type strains of Leucobacter species was lower than 97.2 %. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between the IMT-300T genome assembly and those of the closest relative Leucobacter type strain were 81.4 and 23.3 % ( Leucobacter chironomi ), respectively. The peptidoglycan of strain IMT-300T contained l-2,4-diaminobutyric acid as the diagnostic diamino acid. In addition, glycine, d- and l-alanine and d-glutamic acid were found. The peptidoglycan type represents a variant of B2δ (B11). The major quinones were menaquinones MK-10 and MK-11. The polar lipid profile consisted of the major lipids diphosphatidylglycerol, phosphatidylglycerol and moderate to minor amounts of two unidentified phospholipids, two unidentified glycolipids and an unidentified aminophospholipid. The polyamine pattern contained major amounts of spermidine and spermine. Strain IMT-300T contained the major fatty acids C15 : 0 anteiso, C16 : 0 iso and C17 : 0 anteiso, like other members of the genus Leucobacter . The results of ANI and dDDH analyses and physiological and biochemical tests allowed a genotypic and phenotypic differentiation of strain IMT-300T from the most closely related Leucobacter species. Strain IMT-300T represents a novel Leucobacter species, for which we propose the name Leucobacter soli sp. nov., with the type strain IMT-300T (CIP 111803T=DSM 110505T=CCM 9020T=LMG 31600T).

A Gram-stain-positive, rod-shaped, non-endospore-forming, orange-pigmented (coloured) actinobacterium (01-Je-003T) was isolated from the wall of an indoor environment primarily colonized with moulds. On the basis of 16S rRNA gene sequence similarity studies, strain 01-Je-003T was shown to belong to the genus Brevibacterium and was most similar to the type strains of Brevibacterium picturae (98.8 % similarity), Brevibacterium marinum (97.3 %) and Brevibacterium aurantiacum (97.2 %). Chemotaxonomic data [predominant quinone menaquinone MK-8(H2); polar lipid profile consisting of major compounds diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid; characteristic cell-wall diamino acid meso-diaminopimelic acid; polyamine pattern showing major compounds putrescine and cadaverine; major fatty acids anteiso-C15 : 0 and anteiso-C17 : 0] supported the affiliation of strain 01-Je-003T to the genus Brevibacterium. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 01-Je-003T from the two most closely related species, B. picturae and B. marinum. Strain 01-Je-003T therefore represents a novel species, for which the name Brevibacterium sandarakinum sp. nov. is proposed, with the type strain 01-Je-003T (=DSM 22082T =CCM 7649T).

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.

A Gram-stain-positive, coccoid, non-endospore-forming actinobacterium (Sj14aT) was isolated from the air of a duck barn on tryptone soy agar after filter sampling. On the basis of 16S rRNA gene sequence similarity studies, strain Sj14aT was shown to belong to the genus Dietzia and was most closely related to Dietzia schimae (98.7 %), Dietzia cercidiphylli (98.4 %) and Dietzia maris (98.6 %). The major menaquinone was MK-8 (H2). The polar lipid profile included the major components diphosphatidylglycerol, phosphatidylglycerol, an unknown polar lipid and two unknown glycolipids. Phosphatidylinositol and two phosphatidylinositol mannosides, as well as several other unknown lipids, were also detected. The polyamine pattern contained the major compounds spermine and spermidine. The fatty acid profile, containing C16 : 0, C17 : 0, C18 : 1 ω9c and 10-methyl C18 : 0 as major fatty acids, supported the affiliation of strain Sj14aT to the genus Dietzia. The results of physiological and biochemical tests and DNA–DNA hybridizations allowed a clear phenotypic differentiation of strain Sj14aT from the most closely related species of the genus Dietzia. Strain Sj14aT represents a novel species, for which the name Dietzia aerolata sp. nov. is proposed, with the type strain Sj14aT (=DSM 45334T =CCM 7659T).

A novel Gram-stain-negative, aerobic, rod-shaped bacterium, designated strain 522T, was isolated from surface-sterilized root tissue of maize planted in Fangshan District of Beijing, China. A polyphasic taxonomic study was performed on the new isolate. On the basis of 16S rRNA gene sequence similarity studies, this isolate belonged to the genus Flavobacterium and showed less than 93.9 % similarity to the type strains of all recognized species of the genus Flavobacterium. The predominant respiratory quinone was menaquinone-6 and the polar lipid profile was composed of the major lipids phosphatidylethanolamine, phosphatidylserine and two unidentified amino lipids. The major fatty acids were C15 : 0, iso-C15 : 0, iso-C15 : 1 G and iso-C16 : 0.The G+C content of the DNA was 37.7 mol%. The results of physiological and biochemical tests and the differences in fatty acid profiles allowed the clear phenotypic differentiation of strain 522T from closely related species of the genus Flavobacterium. Strain 522T therefore represents a novel species within the genus Flavobacterium, for which the name Flavobacterium endophyticum sp. nov. is proposed. The type strain is 522T ( = ACCC 19708T = DSM 29537T).

A Gram-stain-positive bacterium, strain RV15T, forming an extensively branched substrate mycelium and aerial hyphae that differentiate into spiral chains of spores, was isolated from a marine sponge Dysidea tupha collected from Rovinj (Croatia). Comparison of 16S rRNA gene sequences showed that strain RV15T is a member of the genus Streptomyces with highest sequence similarity to the type strains of Streptomyces caeruleatus (98.8 %), Streptomyces cyaneochromogenes (98.6 %) and Streptomyces shaanxiensis (98.5 %). Sequence similarities to all other Streptomyces types strains were below 98.5 %. The multilocus sequence analysis-based evolutionary distance, the average nucleotide identity value and the genome-to-genome distance of strain RV15T and the type strain of S. caeruleatus were clearly below the species cut-off values. Strain RV15T exhibited a quinone system composed of the major menaquinones MK-9(H4), MK-9(H6) and MK-9(H2), typical for the genus Streptomyces . The polar lipid profile of strain RV15T consisted of the predominant compounds diphosphatidylglycerol and phosphatidylethanolamine, moderate amounts of phosphatidylinositol, phosphatidylinositol mannoside, an unidentified lipid and an unidentified phospholipid. Major polyamines were spermine and spermidine. The diagnostic diaminoacid of the peptidoglycan was meso-diaminopimelic acid. The major fatty acids were iso C16 : 0, anteiso C17 : 1 ω9c and anteiso C17 : 0. The results of physiological and biochemical tests allowed further phenotypic differentiation of strain RV15T from its most-related species and hence clearly merits species status. We propose the name Streptomyces dysideae sp. nov. with the type strain RV15T (=DSM 42110T=LMG 27702T).

A Gram-positive, coccoid-shaped organism (strain 02-Je-010T), forming yellow-pigmented colonies was isolated from the wall of an indoor environment. On the basis of 16S rRNA gene sequence similarity studies, it was shown that strain 02-Je-010T belongs to the genus Citricoccus with sequence similarities of 98.9 % to Citricoccus alkalitolerans DSM 15665T and 98.6 % to Citricoccus muralis DSM 14442T. Cell-wall sugars were mannose and glucose. The diagnostic diamino acid of the peptidoglycan was lysine. The major menaquinones detected were MK-9(H2) and MK-8(H2). The polar lipid profile consisted of the major lipids diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol and moderate amounts of two unknown phospholipids and two unknown glycolipids. The fatty acid profile comprised major amounts of anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0. All these data supported the affiliation of strain 02-Je-010T to the genus Citricoccus. The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 02-Je-010T from the two recognized Citricoccus species. For these reasons, strain 02-Je-010T represents a novel species, for which the name Citricoccus parietis sp. nov. is proposed, with the type strain 02-Je-010T (=CCUG 57388T=CCM 7609T).

A Gram-positive bacterium (strain CC-YMP-6T) was isolated from soil samples collected from Yang-Ming Mountain, Taiwan. On the basis of 16S rRNA gene sequence analysis, strain CC-YMP-6T clearly belonged to the genus Virgibacillus and was most closely related to the type strains of Virgibacillus halophilus (96.2 % similarity) and Virgibacillus kekensis (96.3 %). The predominant isoprenoid quinone was menaquinone MK-7 and the polar lipid profile was composed of the major components diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and one unidentified phospholipid plus moderate amounts of two unidentified aminophospholipids and a phospholipid. The polyamine pattern comprised spermidine as the single major component with spermine and putrescine present in minor amounts. The major fatty acids of strain CC-YMP-6T were iso-C15 : 0 and anteiso-C15 : 0. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of strain CC-YMP-6T from all recognized species of the genus Virgibacillus. Strain CC-YMP-6T is therefore considered to represent a novel species of the genus Virgibacillus, for which the name Virgibacillus soli sp. nov. is proposed. The type strain is CC-YMP-6T (=DSM 22952T=CCM 7714T).

Novel Bacteria

Two novel bacteria, designated strains Gsoil 634T and Dae 20T, were isolated in South Korea from soil of a ginseng field and freshwater sediment, respectively and were characterized by a polyphasic approach to clarify their taxonomic positions. Phylogenetic analysis based on 16S rRNA gene sequences indicated that, although they probably represented two distinct species (indicated by a sequence similarity of 96.6 %), both strain Gsoil 634T and strain Dae 20T belonged to the genus Sphingomonas and were most closely related to ‘Sphingomonas humi’ PB323 (97.8 % and 96.7 % sequence similarity, respectively), Sphingomonas kaistensis PB56T (96.8 % and 96.7 %), Sphingomonas astaxanthinifaciens TDMA-17T (96.6 % and 95.4 %) and Sphingomonas jaspsi TDMA-16T (95.6 % and 95.8 %). For both novel strains, the major ubiquinone was Q-10, the major polyamine was homospermidine, the major cellular fatty acids included summed feature 7 (C18 : 1ω7c, C18 : 1ω9t and/or C18 : 1ω12t), C17 : 1ω6c and C16 : 0, and the polar lipids included sphingoglycolipid. These chemotaxonomic data supported the affiliation of both strains to the genus Sphingomonas . However, the DNA–DNA relatedness value between strain Gsoil 634T and ‘Sphingomonas humi’ PB323T was 31 %. Moreover, the results of physiological and biochemical tests allowed the phenotypic differentiation of strains Gsoil 634T and Dae 20T from established members of the genus Sphingomonas . Based on these data, the two isolates represent two novel species in the genus Sphingomonas , for which the names Sphingomonas ginsengisoli sp. nov. (type strain Gsoil 634T = KCTC 12630T = DSM 18094T = LMG 23739T) and Sphingomonas sediminicola sp. nov. (type strain Dae 20T  = KCTC 12629T = DSM 18106T = LMG 23592T) are proposed.

Sequence Similarities

Two novel strains belonging to the phylum Bacteroidetes [formerly the Cytophaga–Flexibacter–Bacteroides (CFB) group], designated Gsoil 040T and Gsoil 052T, were isolated from the soil of a ginseng field in Pocheon province, South Korea. A polyphasic approach was used to characterize the taxonomic position of the novel strains. Both strains were Gram-negative, aerobic, non-motile, non-spore-forming and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel isolates belong to the genus Chitinophaga but are clearly separated from the recognized species of this genus; gene sequence similarities between the novel isolates and type strains of recognized species ranged from 91.2 to 96.5 %. One exception was found; strain Gsoil 052T and the type strain of Chitinophaga filiformis had a gene sequence similarity of 99.6 % but had a DNA–DNA relatedness value of 38 %. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; major fatty acids, iso-C15 : 0 and C16 : 1 ω5c; major hydroxy fatty acid, iso-C17 : 0 3-OH and major polyamine, homospermidine) supported the affiliation of both strains Gsoil 040T and Gsoil 052T to the genus Chitinophaga. The results of physiological and biochemical tests enabled the genotypic and phenotypic differentiation of the novel strains from the other recognized species of the genus Chitinophaga. Therefore, it is suggested that the new isolates represent two novel species, for which the names Chitinophaga ginsengisegetis sp. nov. [type strain Gsoil 040T (=KCTC 12654T=DSM 18108T)] and Chitinophaga ginsengisoli sp. nov. [type strain Gsoil 052T (=KCTC 12592T=DSM 18017T)] are proposed.
