Water Cooling System

A motile, rod-shaped, yellow-pigmented bacterium, designated strain CW1T, was isolated from a water-cooling system in the Republic of Korea. Cells were Gram-stain-positive, aerobic, catalase-positive and oxidase-negative. Strain CW1T formed slender rods with unusual bulbous protuberances. The major fatty acids were iso-C16 : 1 (33.7 %), anteiso-C15 : 0 (27.2 %), iso-C14 : 0 (13.3 %) and C16 : 0 (10.8 %). The cell-wall peptidoglycan was of type B2β, containing lysine as the diamino acid. The respiratory quinones were menaquinones with 12, 13 and 14 isoprene units. A phylogenetic tree based on 16S rRNA gene sequences showed that strain CW1T formed an evolutionary lineage within the radiation enclosing members of the family Microbacteriaceae and was related to, but distant from, members of the genera Microcella and Yonghaparkia. On the basis of the evidence presented, strain CW1T is considered to represent a novel species of a new genus in the family Microbacteriaceae, for which the name Chryseoglobus frigidaquae gen. nov., sp. nov. is proposed. The type strain of Chryseoglobus frigidaquae is CW1T (=KCTC 13142T =JCM 14730T).

A novel actinobacterium, designated strain C4-31T, was isolated from soil collected from a cave. Cells were aerobic, Gram-reaction-positive, oxidase-negative, catalase-positive and non-motile cocci. Comparison of 16S rRNA gene sequences showed that the organism occupied a distinct phylogenetic position within the suborder Frankineae, with sequence similarity values of less than 93.2 % to members of this suborder. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, an unknown aminophospholipid and an unknown phospholipid. The major fatty acids were iso-C16 : 0, C17 : 1ω6c and C16 : 0. The G+C content of the DNA was 62.8 mol%. On the basis of morphological and chemotaxonomic data as well as phylogenetic evidence, strain C4-31T ( = KCTC 39556T = DSM 100065T) is considered to represent the type strain of a novel species of a new genus in the suborder Frankineae, for which the name Antricoccus suffuscus gen. nov., sp. nov. is proposed.

A novel Gram-positive, non-motile, rod-shaped bacterium, designated strain RB-62T, was isolated during a study of culturable bacteria from the gut of Moechotypa diphysis (Pascoe) and its taxonomic position was investigated. Strain RB-62T grew at 15–30 °C and pH 5.0–8.5. The isoprenoid quinones were menaquinones MK-11 (77.1 %), MK-10 (11.7 %) and MK-12 (11.2 %). The major cellular fatty acids were anteiso-C15 : 0 (34.6 %), anteiso-C17 : 0 (29.8 %), iso-C16 : 0 (17.0 %) and cyclohexyl-C17 : 0 (11.4 %). The diagnostic diamino acid of the cell-wall peptidoglycan was 2,4-diaminobutyric acid. The G+C content of the genomic DNA of strain RB-62T was 70.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RB-62T was affiliated with the genus Herbiconiux cluster within the family Microbacteriaceae, and was related most closely to Herbiconiux ginsengi wged11T (98.08 % similarity). The level of DNA–DNA relatedness between strain RB-62T and H. ginsengi wged11T was 43.2 % (reciprocal 66.7 %). Phenotypic and phylogenetic characteristics clearly distinguished strain RB-62T from recognized species of the genus Herbiconiux. Based on data from the present polyphasic study, strain RB-62T is considered to represent a novel species of the genus Herbiconiux, for which the name Herbiconiux moechotypicola sp. nov. is proposed. The type strain is RB-62T ( = KCTC 19653T = JCM 16117T).

Three bacterial strains, designated CCUG 51397T, CCUG 53736 and CCUG 53920, isolated from water samples taken at different locations in southern Sweden were studied to determine their taxonomic position using a polyphasic approach. Comparative analysis of 16S rRNA gene sequences showed that these bacteria had <93 % sequence similarity to all described species of the genera Sediminibacterium, Lacibacter, Flavihumibacter, Flavisolibacter, Niabella, Niastella, Segetibacter, Parasegetibacter, Terrimonas, Ferruginibacter, Filimonas and Chitinophaga. The three organisms grouped most closely with Sediminibacterium salmoneum NJ-44T but showed only 92.5 % sequence similarity to this strain, the only recognized species of this genus. The fatty acid profiles showed large amounts of iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G with smaller amounts of iso-C15 : 0 3-OH, iso-C16 : 0 3-OH and other fatty acids, which differentiated the novel strains from related genera. Biochemical tests performed on strains CCUG 51397T, CCUG 53736 and CCUG 53920 also gave different results from those of Sediminibacterium salmoneum NJ-44T and other related genera. Based on this evidence, strains CCUG 51397T, CCUG 53736 and CCUG 53920 represent a novel species of a new genus, for which the name Hydrotalea flava gen. nov., sp. nov. is proposed. The type strain of Hydrotalea flava is CCUG 51397T (=CCM 7760T). A formal allocation of the genera Sediminibacterium, Lacibacter, Flavihumibacter, Flavisolibacter, Niabella, Niastella, Segetibacter, Parasegetibacter, Terrimonas, Ferruginibacter, Filimonas and Chitinophaga to the family Chitinophagaceae fam. nov. is also proposed.

Distinct Lineage

A taxonomic study was performed on three strains isolated from microbial mats in Lake Fryxell, McMurdo Dry Valleys, Antarctica. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these strains belong to the family Flavobacteriaceae, in which they form a distinct lineage. The isolates are Gram-negative, chemoheterotrophic, aerobic, rod-shaped cells. They are psychrophilic and yellow-pigmented, with DNA G+C contents in the range 37·8–38·9 mol%. Whole-cell fatty acid profiles revealed mainly branched fatty acids and 17 : 0 2-OH. On the basis of genotypic, phenotypic, chemotaxonomic and phylogenetic results, it is proposed that the isolates represent a novel species in a new genus, Gillisia limnaea gen. nov., sp. nov. The type strain is LMG 21470T (=DSM 15749T).

Phyllosphere Bacteria

In the context of studying the effects of transgenic fructan-producing potatoes on the community structure of phyllosphere bacteria, a group of strains closely related to the species Leifsonia ginsengi was isolated. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the new isolates and L. ginsengi DSM 19088T formed a lineage at the genus level and this finding was supported by chemotaxonomic characterization. The peptidoglycan type of the representative isolate, K134/01T, and L. ginsengi DSM 19088T was B2γ, with d- and l-diaminobutyric acid as the diagnostic diamino acid and glycine, alanine and threo-3-hydroxyglutamic acid. The almost-complete substitution of glutamic acid by threo-3-hydroxyglutamic acid supported the differentiation of the new strains from recognized species of the genus Leifsonia. Furthermore, the detection of substantial amounts of the fatty acid cyclohexyl-C17 : 0 in the new isolates and L. ginsengi DSM 19088T was a prominent chemotaxonomic feature for a clear demarcation of these strains from all genera of the family Microbacteriaceae that display the B2γ cell-wall type. Comparative phylogenetic and phenotypic analyses of the isolates and L. ginsengi DSM 19088T revealed the separate species status of the isolates. On the basis of these results, it is proposed that L. ginsengi should be classified as the type species of a novel genus, Herbiconiux gen. nov., with the name Herbiconiux ginsengi gen. nov., comb. nov. (type strain wged11T = CGMCC 4.3491T = JCM 13908T = DSM 19088T = NBRC 104580T). The phyllosphere isolates are assigned to a novel species, Herbiconiux solani sp. nov. (type strain K134/01T = DSM 19813T = LMG 24387T = NBRC 106740T).

A Gram-reaction-negative, aerobic, non-flagellated, rod-shaped bacterium, designated strain SM1211T, was isolated from Antarctic seawater. The isolate grew at 4–35 °C and with 0–10 % (w/v) NaCl. It could produce bacteriochlorophyll a, but did not reduce nitrate to nitrite or hydrolyse DNA. Phylogenetic analysis of 16S rRNA gene sequences revealed that strain SM1211T constituted a distinct phylogenetic line within the family Rhodobacteraceae and was closely related to species in the genera Litorimicrobium , Leisingera , Seohaeicola and Phaeobacter with 95.1–96.0 % similarities. The predominant cellular fatty acid was C18 : 1ω7c. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid and two unidentified phospholipids. The genomic DNA G+C content of strain SM1211T was 60.7 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data obtained in this study, strain SM1211T is considered to represent a novel species in a new genus within the family Rhodobacteraceae , for which the name Puniceibacterium antarcticum gen. nov., sp. nov. is proposed. The type strain of Puniceibacterium antarcticum is SM1211T ( = CCTCC AB 2013147T = KACC 16875T).

A Gram-positive, aerobic, non-motile actinobacterium, designated strain 6014T, was isolated from a soil sample collected from Qinghai province, north-west China, and subjected to a polyphasic taxonomic study. The isolate formed elementary branching hyphae and abundant aerial mycelia with globose sporangia on ISP 4 and R2A media. Whole-cell hydrolysates of strain 6014T contained arabinose, galactose and ribose as diagnostic sugars and meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipids consisted of phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, N-acetylglucosamine-containing phospholipids, two unknown phospholipids and an unknown glycolipid. The menaquinone system contained MK-9(H2) and MK-9(H4). The major fatty acids were C14 : 0, i-C15 : 0, C16 : 0 and 10-methyl-C16 : 1. The genomic DNA G+C content of the isolate was 69.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 6014T fell within the radius of the suborder Streptosporangineae, in which the strain formed a distinct lineage next to genera of the family Streptosporangiaceae. Based on data from this polyphasic study, strain 6014T can be readily distinguished from previously described organisms and represents a member of a novel species within a new genus in the suborder Streptosporangineae. The name Sinosporangium album gen. nov., sp. nov. is proposed with 6014T (=DSM 45181T =KCTC 19655T) as the type strain.
