Emended Description

A novel Gram-negative, non-motile, facultative anaerobic and rod-shaped bacterium, designated strain LEN33T, was isolated from the intestinal tract of a butterfly (Mycalesis gotama). Strain LEN33T grew optimally at 37 °C in the presence of 1 % (w/v) NaCl and at pH 9. The novel strain was oxidase-negative and catalase-positive. The major cellular fatty acids were C14 : 0, C16 : 0 and cyclo-C17 : 0. Strain LEN33T contained two unidentified lipids, three unidentified amino-phospholipids, phosphatidylethanolamine (PE) and phosphatidylglycerol (PG). The major isoprenoid quinone was ubiquinone-8 (Q-8). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain LEN33T was most closely related to Gibbsiella quercinecans FRB 97T and Gibbsiella dentisursi NUM 1720T, with 98.7 % similarities. DNA–DNA hybridization experiments indicated less than 40.7±2 % relatedness to the closest phylogenetic species, G. quercinecans FRB 97T. The G+C content of genomic DNA was 58.7 mol%. Phenotypic, phylogenetic and genotypic analysis indicated that strain LEN33T represents a novel species within the genus Gibbsiella , for which the name Gibbsiella papilionis is proposed. The type strain is referred to as LEN33T ( = KACC 16707T = JCM 18389T). An emended description of the genus Gibbsiella is also proposed.

Emended Description

A Gram-negative, aerobic, copper-resistant bacterium, designated strain CU4T, was isolated from copper mine soil in Daye, China. Phylogenetic analysis based on 16S rRNA gene sequences showed highest similarity to Sphingobium rhizovicinum CC-FH12-1T (98.4 %), followed by Sphingobium francense Sp+T (97.2 %), Sphingobium japonicum UT26T (97.1 %), Sphingobium abikonense NBRC 16140T (97.0 %), Sphingobium xenophagum DSM 6383T (96.9 %) and Sphingobium yanoikuyae DSM 7462T (95.5 %). The major fatty acids (>5 %) were summed feature 7 (C18 : 1ω7c, C18 : 1ω9t and/or C18 : 1ω12t), summed feature 4 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and C14 : 0 2-OH, and the predominant quinone was ubiquinone Q-10. Spermidine was the major polyamine component. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, phosphatidyldimethylethanolamine and phosphatidylcholine. The genomic DNA G+C content of strain CU4T was 64.9 mol%. Comparison of DNA–DNA hybridization, phenotypic and chemotaxonomic characteristics between strain CU4T and phylogenetically related strains revealed that the new isolate represents a novel species of the genus Sphingobium , for which the name Sphingobium cupriresistens sp. nov. is proposed. The type strain is CU4T ( = KCTC 23865T = CCTCC AB 2011146T). An emended description of the genus Sphingobium is also proposed.

Emended Description

Strains 1-1NT and GYSZ_1T were isolated from marine sediments collected from the coast of Xiamen, PR China. Cells of the two strains were Gram-stain-negative, rod-shaped or slightly curved. Strain 1-1NT was non-motile, whereas strain GYSZ_1T was motile by means of one polar flagellum. The temperature, pH and salinity concentration ranges for growth of 1-1NT were 10–45 °C (optimum 30 °C), pH 5.5–8.0 (optimum 7.0) and 0–90 g l−1 NaCl (optimum 50 g l−1), while the growth of GYSZ_1T occurred at 4–45 °C (optimum 33 °C), pH 5.0–8.5 (optimum 6.5) and 5–90 g l−1 NaCl (optimum 20 g l−1). The two novel isolates were obligate chemolithoautotrophs capable of growth using hydrogen, thiosulfate, sulfide or elemental sulfur as the sole energy source, and nitrate, elemental sulfur or molecular oxygen as an electron acceptor. The major fatty acids of 1-1NT were C16 : 1ω7c, C16 : 0, C18 : 1ω7c and C18 : 0, while the predominant fatty acids of strain GYSZ_1T were C16 : 1ω7c, C16 : 0, C18 : 1ω7c and C14 : 0 3-OH. The DNA G+C contents of 1-1NT and GYSZ_1T were 34.5 mol% and 33.2 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that 1-1NT and GYSZ_1T represented members of the genus Sulfurimonas , with the highest sequence similarities to Sulfurimonas crateris SN118T (97.4 %) and Sulfurimonas denitrificans DSM 1251T (94.7 %), respectively. However, 1-1NT and GYSZ_1T shared 95.5 % similarity of 16S rRNA gene sequences, representing different species of the genus Sulfurimonas . On the basis of the physiological properties and the results of phylogenetic analyses, including average nucleotide identity and in silico DNA–DNA hybridization values, strains 1-1NT and GYSZ_1T represent two novel species within the genus Sulfurimonas , for which the names Sulfurimonas xiamenensis sp. nov. and Sulfurimonas lithotrophica sp. nov. are proposed, with the type strains 1-1NT (=MCCC 1A14514T=KCTC 15851T) and GYSZ_1T (=MCCC 1A14739T=KCTC 15853T), respectively. Our results also justify an emended description of the genus Sulfurimonas .

Type Strains

Four strains (JA310T, JA531T, JA447 and JA490) of red to reddish brown pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from soil and freshwater sediment samples from different geographical regions of India. All strains contained bacteriochlorophyll a and carotenoids of the spirilloxanthin series. The major cellular fatty acid of strains JA310T and JA531T was C18 : 1ω7c, the quinone was Q-10 and polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an aminohopanoid and an unidentified aminolipid. Phylogenetic analysis based on 16S rRNA gene sequences showed that all strains clustered with species of the genus Rhodopseudomonas in the class Alphaproteobacteria . Strains JA531T, JA447 and JA490 were genotypically (>80 % related based on DNA–DNA hybridization) and phenotypically closely related to each other and the three strains were distinct from strain JA310T (33 % related). Furthermore, all four strains had less than 48 % relatedness (DNA–DNA hybridization) with type strains of members of the genus Rhodopseudomonas , i.e. Rhodopseudomonas palustris ATCC 17001T, Rhodopseudomonas faecalis JCM 11668T and Rhodopseudomonas rhenobacensis DSM 12706T. The genomic DNA G+C contents of strains JA310T and JA531T were 63.8 and 62.4 mol%, respectively. On the basis of phenotypic, chemotaxonomic and molecular genetic evidence, it is proposed that strains JA310T ( = NBRC 106083T = KCTC 5839T) and JA531T ( = NBRC 107575T = KCTC 5841T) be classified as the type strains of two novel species of the genus Rhodopseudomonas , Rhodopseudomonas parapalustris sp. nov. and Rhodopseudomonas harwoodiae sp. nov., respectively. In addition, we propose that strain DSM 123T ( = NBRC 100419T) represents a novel species, Rhodopseudomonas pseudopalustris sp. nov., since this strain differs genotypically and phenotypically from R. palustris ATCC 17001T and other members of the genus Rhodopseudomonas . An emended description of R. palustris is also provided.

Two novel strains, T9T and T10, were isolated from water samples collected from Chishui River flowing through Maotai town, Guizhou, south-west China. The isolates were yellow-pigmented, Gram-reaction-negative, rod-shaped, non-motile and aerobic. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolates belonged to the genus Flavobacterium , and showed highest similarities to Flavobacterium hibernum DSM 12611T (97.0 %), followed by Flavobacterium granuli Kw05T (96.7 %) and Flavobacterium pectinovorum DSM 6368T (96.7 %). The novel strains were able to grow at 20–37 °C (optimum 25 °C), pH 7.0–10.0 (optimum pH 7.0–8.0) and with 0–0.5 % (w/v) NaCl (optimum 0.5 %). The predominant fatty acids were iso-C15 : 0, C16 : 1ω7c, anteiso-C15 : 0, C15 : 0, iso-C15 : 0 3-OH and iso-C15 : 1ω10c, and menaquinone-6 (MK-6) was the main respiratory quinone. The major polar lipids were phosphatidylethanolamine, one unknown glycolipid, two unknown aminolipids and two unidentified lipids. The DNA G+C contents of strains T9T and T10 were 37.7 and 36.4 mol%, respectively. According to the phenotypic and genetic data, strains T9T and T10 represent a novel species in the genus Flavobacterium , for which the name Flavobacterium maotaiense sp. nov. is proposed. The type strain is T9T ( = CGMCC 1.12712T = JCM 19927T).

A non-motile and rod-shaped bacterium, designated strain 02SUJ3T, was isolated from freshwater collected from the Juam Reservoir (Republic of Korea). Cells were Gram-stain-negative, aerobic, oxidase-negative and catalase-positive. The major fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The strain contained MK-7 as the major isoprenoid quinone. The main polar lipid was phosphatidylethanolamine. The DNA G+C content was 46.4 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 02SUJ3T forms an independent lineage within the genus Flavisolibacter with low sequence similarity to Flavisolibacter ginsengiterrae Gsoil 492T and Flavisolibacter ginsengisoli Gsoil 643T (95.7 %). Phenotypic characteristics distinguished strain 02SUJ3T from members of the genus Flavisolibacter . On the basis of the evidence presented in this study, strain 02SUJ3T is considered to represent a novel species, for which the name Flavisolibacter rigui sp. nov. is proposed. The type strain is 02SUJ3T ( = JCM 17515T = KCTC 23328T). An emended description of the genus Flavisolibacter is also provided.

A Gram-stain-negative, aerobic, non-motile and rod- or coccoid-shaped novel bacterial strain, designated MAH-25T, was isolated from soil sampled in a pine garden. The colonies were observed to be light pink-coloured, smooth, spherical and 1–2 mm in diameter when grown on nutrient agar for 2 days. Strain MAH-25T was found to be able to grow at 15–35 °C, at pH 5.0–8.0 and at 0–2.0 % NaCl. Cell growth occurred on Reasoner's 2A agar and nutrient agar. The strain was found to be positive in both oxidase and catalase tests. According to 16S rRNA gene sequence comparisons, the isolate was identified as a member of the genus Ramlibacter and closely related to Ramlibacter solisilvae 5-10T (98.0 % similarity), Ramlibacter henchirensis TMB834T (97.7 %), Ramlibacter tataouinensis TTB310T (97.6 %) and Ramlibacter rhizophilus YS3.2.7T (97.3 %). The average nucleotide identity and digital DNA–DNA hybridization values between strain MAH-25T and the four closely related type strains were in the range of 78.8–81.3 % and 22.3–24.1 %, respectively. The novel strain MAH-25T has a draft genome size of 5 505 957 bp (11 contigs), annotated with 5210 protein-coding genes, 46 tRNA and three rRNA genes. The genomic DNA G+C content was determined to be 70.3 mol%. The predominant isoprenoid quinone was ubiquinone 8 (Q-8). The major fatty acids were identified as C16 : 0, summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c). The main polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. On the basis of DNA–DNA hybridization, genotypic analysis, chemotaxonomic and physiological data, strain MAH-25T represents a novel species within the genus Ramlibacter , for which the name Ramlibacter pinisoli sp. nov. is proposed, with MAH-25T (=KACC 19839T=CGMCC1.13660T) as the type strain.

Two endophytic strains, coded MOVP5T and MOPV6, were isolated from nodules of Phaseolus vulgaris plants grown on agricultural soil in Southeastern Spain, and were characterized through a polyphasic taxonomy approach. Their 16S rRNA gene sequences showed 99.3 and 99.4 %, 98.9 and 99.6 %, and 99.0 and 98.7% similarity to ‘ A. deltaense ’ YIC 4121T, A. radiobacter LGM 140T, and A. pusense NRCPB10T, respectively. Multilocus sequence analysis based on sequences of recA and atpD genes suggested that these two strains could represent a new Agrobacterium species with less than 96.5 % similarity to their closest relatives. PCR amplification of the telA gene, involved in synthesis of protelomerase, confirmed the affiliation of strains MOPV5T and MOPV6 to the genus Agrobacterium . Whole genome average nucleotide identity and digital DNA–DNA hybridization average values were less than 95.1 and 66.7 %, respectively, with respect to its closest related species. Major fatty acids in strain MOPV5T were C18 : 1 ω7c/C18 : 1 ω6c in summed feature 8, C19 : 0 cyclo ω8c, C16 : 0 and C16 : 0 3-OH. Colonies were small to medium, pearl-white coloured on YMA at 28 °C and growth was observed at 10–42 °C, pH 5.0–10.0 and with 0.0–0.5 % (w/v) NaCl. The DNA G+C content was 59.9 mol%. These two strains differ from all other genomovars of Agrobacterium found so far, including those that have not yet given a Latin name. The combined genotypic, phenotypic and chemotaxonomic data support the classification of strain MOPV5T as representing a novel species of Agrobacterium , for which the name Agrobacterium leguminum sp. nov. is proposed. The type strain is MOPV5T (=CECT 30096T=LMG 31779T).

A Gram-stain-positive, novel actinobacterium, designated strain JL-6T, was isolated from the litter of a bamboo (Sasa borealis) forest in Damyang, Korea. Strain JL-6T had white‐grey, smooth, cylindrical spores that were borne in straight, long spore-chains. The novel strain grew aerobically at 15–28 °C (optimum, 28 °C), pH 4.0–8.0 (optimum, pH 5.5) and with 0–1.5 % (w/v) NaCl. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glutamic acid, alanine and glycine. The predominant menaquinones were MK-9(H6) and MK-9(H8). Whole-cell hydrolysates mainly contained glucose and ribose. Phosphatidylinositol and phosphatidylcholine were the diagnostic phospholipids. The G+C content of the genomic DNA was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JL-6T belonged to the genus Streptomyces with sequence similarities ranging from 97.3 % to 98.3 %. However, DNA–DNA hybridization between JL-6T and the closest related strain, Streptomyces turgidiscabies , ATCC 700248T and other closely related species in the genus Streptomyces showed <50 % relatedness. Based on these observations, strain JL-6T is proposed to represent a novel species of the genus Streptomyces , for which the name Streptomyces graminilatus sp. nov. is proposed. The type strain is JL-6T ( = KACC 16470T = NBRC 108882T).
