Major Respiratory Quinone

A Gram-stain-negative bacterium, designated XIN-1T, was isolated from a farmland river sludge sample in Suzhou, China. Cells of strain XIN-1T were strictly aerobic, non-motile and rod-shaped. Strain XIN-1T grew optimally at pH 7.0 and 28 °C. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain XIN-1T was most closely related to Flavobacterium hauense BX12T (98.2 % sequence similarity), followed by Flavobacterium beibuense F44-8T (96.3 %). The major respiratory quinone was menaquinone-6 and the major polar lipid was phosphatidylethanolamine. The major fatty acids (>5 %) were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), summed feature 4 (comprising iso-C17 : 1 I and/or anteiso-C17 : 1 B), iso-C15 : 0, C16 : 0 and iso-C17 : 0 3-OH. The genomic DNA G+C content of strain XIN-1T was 39.8 mol%. Strain XIN-1T showed low DNA–DNA relatedness with F. hauense BX12T (38.7±0.5 %). On the basis of genotypic and phenotypic data, strain XIN-1T is considered to represent a novel species of the genus Flavobacterium , for which the name Flavobacterium suzhouense sp. nov. is proposed. The type strain is XIN-1T ( = CCTCC AB 2014200T = KCTC 42107T).

Two Gram-stain-negative, non-motile, rod-shaped bacterial strains were isolated from the surfaces of rice roots. They were designated as strains 1303T and 1310. Their colonies were circular, entire, opaque, convex and yellow. They were chitinase- and catalase-positive, reduced nitrate and grew at 16–37 °C (optimum, 30 °C), pH 5.0–10.0 (optimum, pH 7.0) and 0–2.0% NaCl (optimum, 1.0 %). Based on the 16S rRNA gene sequence analysis, they were classified as members of the genus Chitinophaga . Results of phylogenetic and phylogenomic analyses indicated that they formed a cluster with Chitinophaga eiseniae YC6729T, Chitinophaga qingshengii JN246T, Chitinophaga varians 10-7 W-9003T and Chitinophaga fulva G-6-1-13T. When the genomic sequences of strains 1303T and 1310 were compared with their close relatives, the average nucleotide identity and digital DNA–DNA hybridization values were below the cut-off levels. Phosphatidylethanolamine was the major polar lipid. MK-7 was the major respiratory quinone. iso-C15 : 0, C16 : 1  ω5c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c) were the predominant fatty acids. Differential characteristics between both strains and their close relatives were also observed. Based on the distinctions in genotypic, phenotypic and chemotypic features, strains 1303T and 1310 represent members of a novel species of the genus Chitinophaga , for which the name Chitinophaga oryzae sp. nov. is proposed. The type strain is 1303T (=KACC 22075T=TBRC 12926T).

Two Gram-stain-negative, yellow-pigmented and strictly aerobic bacteria, designated strains SE-s27T and SE-s28T, were isolated from forest soil. Both strains were non-motile rods that were catalase-positive and oxidase-negative and grew optimally at 25–30 °C, pH 8.0 and with 0 % (w/v) NaCl. Strain SE-s28T produced flexirubin-type pigments, but strain SE-s27T did not produce them. Both strains contained menaquinone-6 as the sole respiratory quinone and phosphatidylethanolamine as a major polar lipid. As the major cellular fatty acids (>10 %), SE-s27T contained iso-C15 : 1 and iso-C15 : 1G, whereas SE-s28T contained iso-C15 : 0 and summed feature 3 comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH. The DNA G+C contents of strains SE-s27T and SE-s28T were 33.1 and 44.3 mol%, respectively. The results of phylogenetic analysis based on 16S rRNA gene sequences revealed that SE-s27T and SE-s28T formed respective distinct phylogenetic lineages within the genus Flavobacterium . Strains SE-s27T and SE-s28T were most closely related to Flavobacterium macrobrachii an-8T and Flavobacterium piscinae ICH-30T with 98.0 and 94.5 % 16S rRNA gene sequence similarities, respectively. In conclusion, strains SE-s27T and SE-s28T represent novel species of the genus Flavobacterium , for which the names Flavobacterium solisilvae sp. nov. and Flavobacterium silvaticum sp. nov. are proposed. The type strains of F. solisilvae and F. silvaticum are SE-s27T (=KACC 18802T=JCM 31544T) and SE-s28T (=KACC 18803T=JCM 31545T), respectively.

Taxonomic Approach

A bacterial strain, designated NSW-5T, was isolated from a water sample taken from Niao-Song Wetland Park in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain NSW-5T were strictly aerobic, Gram-stain-negative, non-motile and polymorphic, being straight, vibrioid, curved and spiral-shaped rods surrounded by a thick capsule and forming light pink-coloured colonies. Some rings consisting of several cells were present. Growth occurred at 10–40 °C (optimum, 25 °C), with 0–3.0 % NaCl (optimum, 0 %) and at pH 6.0–8.0 (optimum, pH 7.0). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain NSW-5T belonged to the genus Arcicella with sequence similarities of 98.6, 98.0 and 97.3 % with Arcicella aquatica NO-502T, Arcicella rosea TW5T and Arcicella aurantiaca TNR-18T, respectively. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 20.8 %), C16 : 0 (14.6 %), iso-C15 : 0 (13.8 %), C16 : 1ω5c (12.5 %) and C18 : 0 (11.4 %), and the only respiratory quinone was MK-7. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized glycolipids, aminolipids, phospholipids and aminophospholipids. The DNA G+C content of strain NSW-5T was 44.1 mol%. The DNA–DNA relatedness of strain NSW-5T with respect to recognized species of the genus Arcicella was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain NSW-5T should be classified as a representative of a novel species, for which the name Arcicella rigui sp. nov. is proposed. The type strain is NSW-5T ( = KCTC 23307T = BCRC 80260T). Emended descriptions of the genus Arcicella and of Arcicella aquatica , Arcicella rosea and Arcicella aurantiaca are also proposed.

A strictly aerobic, Gram-negative, yellow-pigmented, non-spore-forming rod, designated 15C3T, was isolated from aerobic leaf-and-branch compost at EXPO Park in Osaka, Japan. Growth was observed at 9–33 °C (optimum 25 °C) and pH 5.6–7.9 (optimum pH 6.1–7.0). No growth occurred with >2 % (w/v) NaCl. Strain 15C3T reduced nitrate to nitrogen and showed catalase activity but not oxidase activity. The predominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH). The isolate contained phosphatidylethanolamine as the major polar lipid and menaquinone-6 as the major respiratory quinone. The G+C content of the genomic DNA of strain 15C3T was 33.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 15C3T belonged to the genus Flavobacterium and was most closely related to Flavobacterium hercynium WB 4.2-33T (96.9 % sequence similarity). On the basis of phenotypic and phylogenetic distinctiveness, strain 15C3T is considered to represent a novel species in the genus Flavobacterium , for which the name Flavobacterium compostarboris sp. nov. is proposed. The type strain is 15C3T ( = KACC 14224T  = JCM 16527T). Emended descriptions of F. hercynium , Flavobacterium resistens and Flavobacterium johnsoniae are also given.

A polyphasic taxonomic study was carried out on strains CHu50b-3-2T and CHu40b-3-1 isolated from a 67 cm-long sediment core collected from the Daechung Reservoir at a water depth of 17 m, Daejeon, Republic of Korea. The cells of the strains were Gram-stain-negative, non-spore-forming, non-motile and rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of two strains with γ-Proteobacteria, which showed the highest pairwise sequence similarities to Lysobacter hankyongensis KTce-2T (96.5 %), Lysobacter pocheonensis Gsoil193T (96.3 %), Lysobacter ginsengisoli Gsoil 357T (96.1 %), Lysobacter solanacearum T20R-70T (96.1 %), Lysobacter brunescens KCTC 12130T (95.4 %) and Lysobacter capsici YC5194T (95.3 %). The phylogenetic analysis based on 16S rRNA gene sequences showed that the strains formed a clear phylogenetic lineage with the genus Lysobacter . The major fatty acids were identified as summed feature 9 (iso-C17 : 1  ω9c and/or C18 : 1 10-methyl), iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0. The respiratory quinone was identified as ubiquinone Q-8. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The genomic DNA G+C content was determined to be 66.8 mol% (genome) for strain CHu50b-3-2T and 66.4 mol% (HPLC) for strain CHu40b-3-1. Based on the combined genotypic and phenotypic data, we propose that strains CHu50b-3-2T and CHu40b-3-1 represent a novel species of the genus Lysobacter , for which the name Lysobacter profundi sp. nov. is proposed. The type strain is CHu50b-3-2T (=KCTC 72973T=CCTCC AB 2019129T). Besides Lysobacter panaciterrae Gsoil 068T formed a phylogenetic group together with strain Luteimonas aquatica RIB1-20T (EF626688) that is clearly separated from all other known Lysobacter strains. Based on the phylogenetic relationships together with fatty acid compositions, Lysobacter panaciterrae Gsoil 068T should be reclassified as a member of the genus Luteimonas: Luteimonas aquatica comb. nov. (type strain Gsoil 068T=KCTC 12601T=DSM 17927T).

A strictly aerobic, bacteriochlorophyll (BChl) a-containing alphaproteobacterium, designated strain K6T, was isolated from seawater around an aquaculture site in the Uwa Sea in Japan. The novel strain grew optimally at 30 °C at pH 7.0–7.5 and in the presence of 2.0 % (w/v) NaCl. The nonmotile and coccoid or rod-shaped cells formed pink-pigmented colonies on agar plates containing organic compounds. Cells showed an in vivo absorption maximum at 870 nm in the near-infrared region, indicating the presence of BChl a in the light-harvesting 1 complex. The new bacterial strain was Gram-stain-negative and oxidase- and catalase-positive. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain K6T was closely related to species in the genus Litoreibacter . The closest phylogenetic relatives of strain K6T were Litoreibacter ponti GJSW-31T (98.56 % sequence similarity), Litoreibacter janthinus KMM 3842T (97.63 %) and Litoreibacter albidus KMM 3851T (96.88 %). The G+C content of the genomic DNA was 58.26 mol%. The average nucleotide identity value of strain K6T with the type strain of L. ponti was 77.16 % (SD 4.79 %). The digital DNA−DNA hybridization value of strain K6T with the type strain of L. ponti was 19.40 %. The respiratory quinone was ubiquinone-10. The major cellular fatty acids were C18 : 1 ω7c, C16 : 0 and 11-methyl C18 : 1 ω7c. The dominant polar lipids were phosphatidylcholine and phosphatidylglycerol. On the basis of the genetic and phenotypic data obtained in the present study, we propose a new species in the genus Litoreibacter : Litoreibacter roseus sp. nov., whose type strain is K6T (=DSM 110109T=NBRC 114114T). Strain K6T represents the first confirmed species that produces BChl a within the genus Litoreibacter .
