Genotypic Identification

Sampling of seafood and dairy processing facilities in the north-eastern USA produced 18 isolates of Listeria spp. that could not be identified at the species-level using traditional phenotypic and genotypic identification methods. Results of phenotypic and genotypic analyses suggested that the isolates represent two novel species with an average nucleotide blast identity of less than 92 % with previously described species of the genus Listeria . Phylogenetic analyses based on whole genome sequences, 16S rRNA gene and sigB gene sequences confirmed that the isolates represented by type strain FSL M6-0635T and FSL A5-0209 cluster phylogenetically with Listeria cornellensis . Phylogenetic analyses also showed that the isolates represented by type strain FSL A5-0281T cluster phylogenetically with Listeria riparia . The name Listeria booriae sp. nov. is proposed for the species represented by type strain FSL A5-0281T ( = DSM 28860T = LMG 28311T), and the name Listeria newyorkensis sp. nov. is proposed for the species represented by type strain FSL M6-0635T ( = DSM 28861T = LMG 28310T). Phenotypic and genotypic analyses suggest that neither species is pathogenic.

Phosphatidylinositol Mannosides

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

Tidal Flat Sediment

A novel Gram-stain-negative, facultatively anaerobic, rod-shaped and non-motile bacterial strain, designated as 4C16AT, was isolated from a tidal flat sediment and characterized by using a polyphasic taxonomic approach. Strain 4C16AT was found to grow at 10–40 °C (optimum, 28 °C), at pH 5.0–10.0 (optimum, pH 6.0–7.0) and in 0–6 % (w/v) NaCl (optimum, 1 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 4C16AT fell into the genus Roseibium , and shared the highest identity of 98.9 % with the closest type strain Roseibium suaedae KACC 13772T and less than 98.0 % identity with other type strains of recognized species within this genus. The phylogenomic analysis indicated that strain 4C16AT formed an independent branch within this genus. The 28.6 % digital DNA–DNA hybridization estimate and 85.0 % average nucleotide identity between strains 4C16AT and R. suaedae KACC 13772T were the highest, but still far below their respective threshold for species definition, implying that strain 4C16AT should represent a novel genospecies. The predominant cellular fatty acid was summed feature 8; the polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylmonomethylethanolamine; the respiratory quinones were Q-9 and Q-10. The genomic DNA G+C content was 59.8mol %. Based on phylogenetic analyses and phenotypic and chemotaxonomic characteristics, strain 4C16AT is concluded to represent a novel species of the genus Roseibium , for which the name Roseibium litorale sp. nov. is proposed. The type strain of the species is 4C16AT (=GDMCC 1.1932T=KACC 22078T). We also propose the reclassification of Labrenzia polysiphoniae as Roseibium polysiphoniae comb. nov. and ‘Labrenzia callyspongiae’ as Roseibium callyspongiae sp. nov.

The Family

Strains RU-16T, RU-28, RU-04T and PU-02T were isolated from the gut of the African mole cricket, Gryllotalpa africana. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strains belonged to the family Microbacteriaceae . All four strains were most closely related to Curtobacterium ginsengisoli DCY26T (below 97 % 16S rRNA gene sequence similarity). These isolates were Gram-stain-positive, motile (by gliding), rod-shaped and exhibited ivory-coloured colonies. Their chemotaxonomic properties included MK-11 as the major respiratory quinone, ornithine as the cell-wall diamino acid, acetyl as the acyl type of the peptidoglycan, cyclohexyl-C17 : 0 as the major fatty acid and phosphatidylglycerol and diphosphatidylglycerol as the major polar lipids. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, we propose a new genus in the family Microbacteriaceae , Gryllotalpicola gen. nov., with three novel species, Gryllotalpicola daejeonensis sp. nov. (type strain RU-04T  = KCTC 13809T  = JCM 17590T), Gryllotalpicola koreensis sp. nov. (type strain RU-16T  = KCTC 13810T  = JCM 17591T) and Gryllotalpicola kribbensis sp. nov. (type strain PU-02T  = KCTC 13808T  = JCM 17593T). Gryllotalpicola koreensis is the type species of the genus. Additionally, we propose that Curtobacterium ginsengisoli should be reclassified in the genus as Gryllotalpicola ginsengisoli comb. nov. (type strain DCY26T  = KCTC 13163T  = JCM 14773T).

Pink-pigmented, facultatively methylotrophic bacteria, strains 87eT and 99bT, were isolated from the bryophytes Haplocladium microphyllum and Brachythecium plumosum, respectively. The cells of both strains were Gram-reaction-negative, motile, non-spore-forming rods. On the basis of 16S rRNA gene sequence similarity, strains 87eT and 99bT were found to be related to Methylobacterium organophilum ATCC 27886T (97.1 % and 97.7 %, respectively). Strains 87eT and 99bT showed highest 16S rRNA gene similarity to Methylobacterium gnaphalii 23eT (98.3 and 99.0 %, respectively). The phylogenetic similarities to all other species of the genus Methylobacterium with validly published names were less than 97 %. Major cellular fatty acids of both strains were C18 : 1ω7c and C18 : 0. The results of DNA–DNA hybridization, phylogenetic analyses based on 16S rRNA and cpn60 gene sequences, fatty acid profiles, whole-cell matrix-assisted, laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) analysis, and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strains 87eT and 99bT from their phylogenetically closest relatives. We propose that strains 87eT and 99bT represent novel species within the genus Methylobacterium , for which the names Methylobacterium haplocladii sp. nov. (type strain 87eT = DSM 24195T = NBRC 107714T) and Methylobacterium brachythecii sp. nov. (type strain 99bT = DSM 24105T = NBRC 107710T) are proposed.

An indigo-reducing facultatively alkaliphilic and halophilic strain, designated strain A21T, was isolated from a fermented Polygonum indigo (Polygonum tinctorium Lour.) liquor sample aged for 4 days prepared in a laboratory. 16S rRNA gene sequence phylogeny suggested that strain A21T was a member of the genus Oceanobacillus with the closest relative being the type strain of Oceanobacillus chironomi (similarity: 96.0 %). The cells of the isolate stained Gram-positive and were facultatively anaerobic straight rods that were motile by peritrichous flagella. The strain grew between 18 and 48 °C with optimum growth at 39 °C. It grew in the pH range of 7–12. It hydrolysed casein, gelatin and Tween 20 but not Tweens 40, 60 and 80, starch or DNA. No isoprenoid quinone was detected and the DNA G+C content was 39.7 mol%. The whole-cell fatty acid profile mainly consisted of iso-C15 : 0, anteiso-C15 : 0 and C16 : 0. DNA–DNA hybridization experiments with O. chironomi revealed 13 % relatedness. Owing to the differences in phenotypic and chemotaxonomic characteristics, and phylogenetic analyses based on 16S rRNA gene sequences and DNA–DNA relatedness data from reported Oceanobacillus species, the isolate merits classification as a representative of a novel species, for which the name Oceanobacillus indicireducens sp. nov. is proposed. The type strain is A21T ( = JCM 17251T  = NCIMB 14685T). The description of the genus Oceanobacillus is also emended.

Four aerobic, Gram-stain-positive, rod-shaped bacteria (HY60T, HY54, HY82T and HY89) were isolated from bat faeces of Hipposideros and Rousettus species collected in PR China. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the four novel strains formed two separate but adjacent subclades close to Microbacterium agarici CGMCC 1.12260T (97.6–97.7 % similarity), Microbacterium humi JCM 18706T (97.3–97.5 %) and Microbacterium lindanitolerans JCM 30493T (97.3–97.4 %). The 16S rRNA gene sequence similarity was 98.3 % between strains HY60T and HY82T, and identical within strain pairs HY60T/HY54 and HY82T/HY89. The DNA G+C contents of strains HY60T and HY82T were 61.9 and 63.3 mol%, respectively. The digital DNA–DNA hybridization and average nucleotide identity values between each novel strain and their closest relatives were all below the 70 % and 95–96 % thresholds for species delimitation, respectively. All four novel strains contained anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0 as the main fatty acids, MK-11 and MK-12 as the major respiratory quinones, and diphosphatidylglycerol, phosphatidylglycerol and one unidentified glycolipid as the predominant polar lipids. The cell-wall peptidoglycan was of B type and contained alanine, glutamate, glycine and ornithine. The acyl type of the muramic acid was glycolyl. The whole-cell sugars were rhamnose and ribose. Based on the foregoing polyphasic analyses, it was concluded that the four uncharacterized strains represented two novel species of the genus Microbacterium , for which the names Microbacterium chengjingii sp. nov. [type strain HY60T (=CGMCC 1.17468T=GDMCC 1.1951T=KACC 22102T)] and Microbacterium fandaimingii sp. nov. [type strain HY82T (=CGMCC 1.17469T=GDMCC 1.1949T=KACC 22101T)] are proposed, respectively.

Two Gram-stain-negative, aerobic, moderately halophilic, rod-shaped bacteria (strains Ar-45T and DY470T) were isolated from seawater collected from the Southern Ocean and the Pacific Ocean, respectively. Growth of strain Ar-45T was observed with between 0.5 and 10.0 % (w/v) NaCl (optimally with 0.5–3.0 %) and between pH 5.5 and 9.5. Strain DY470T grew in the presence of 0.5–7.5 % (w/v) NaCl (optimally with 2.0 %) and at pH 5.5–8.5. Chemotaxonomic analysis showed Q-10 as the respiratory quinone for both strains. The major fatty acids (>5 %) of strain Ar-45T were C16 : 0, C19 : 0 cyclo ω8c and C18 : 1ω7c, while those of strain DY470T were C18 : 1ω7c, C16 : 0 and 11-methyl C18 : 1ω7c. The DNA G+C contents of the two strains were 62.0 and 61.8 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains Ar-45T and DY470T were related most closely to the genus Oceanicola , with sequence similarities of 97.4–94.0 and 97.7–94.7 %, respectively. The DNA–DNA hybridization value between strain Ar-45T and Oceanicola marinus LMG 23705T was 22.0 %. Levels of DNA–DNA relatedness between strain DY470T and Oceanicola nitratireducens LMG 24663T and Oceanicola batsensis DSM 15984T were 32.5 and 26.1 %, respectively. Based on phylogenetic, chemotaxonomic and phenotypic data, strains Ar-45T and DY470T are considered to represent two novel species of the genus Oceanicola , for which the names Oceanicola antarcticus (type strain Ar-45T = CGMCC 1.12662T = LMG 27868T) and Oceanicola flagellatus (type strain DY470T = CGMCC 1.12664T = LMG 27871T) are proposed.

Bacterial strains YM16-303T and YM16-304T were isolated from a sample of seashore sand using a medium with an artificial seawater base. Both isolates grew slowly on marine agar, and were found to be Gram-reaction-positive, aerobic, non-motile and rod-shaped. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glycine, alanine and hydroxyglutamic acid, and the acyl type of the muramic acid was glycolyl. The predominant menaquinone was MK-9(H8). The 16S rRNA gene sequences of strains YM16-303T and YM16-304T were most similar to that of Ilumatobacter fluminis YM22-133T, and phylogenetic analyses also indicated that they belong to the genus Ilumatobacter . Ilumatobacter fluminis YM22-133T and strains YM16-303T and YM16-304T should be classified as distinct species in the genus Ilumatobacter , however, since the 16S rRNA gene sequence similarity between them was low and the major cellular fatty acids and some physiological properties were different. Moreover, average nucleotide identity and maximal unique exact matches index values also supported the conclusion that they represent different species. On the basis of the above analyses, two novel species, Ilumatobacter nonamiense sp. nov. (type strain YM16-303T = NBRC 109120T = KCTC 29139T) and Ilumatobacter coccineum sp. nov. (type strain YM16-304T = NBRC 103263T = KCTC 29153T), are proposed. The order Acidimicrobiales , which contains the genus Ilumatobacter , currently includes six genera and only six species, and they are phylogenetically very far from each other. Phylogenetic analyses revealed that strains YM16-303T and YM16-304T clustered with closely related uncultured actinobacteria but not Ilumatobacter fluminis YM22-133T, suggesting that many uncultured bacteria related to these isolates exist in the environment. This is the first report on interspecies relationships in the order Acidimicrobiales .

Root-nodule bacteria were isolated from Inga laurina (Sw.) Willd. growing in the Cerrado Amazon region, State of Roraima, Brazil. The 16S rRNA gene sequences of six strains (BR 10250T, BR 10248, BR 10249, BR 10251, BR 10252 and BR 10253) showed low similarities with currently described species of the genus Bradyrhizobium . Phylogenetic analyses of sequences of five housekeeping genes (dnaK, glnII, gyrB, recA and rpoB) revealed Bradyrhizobium iriomotense EK05T to be the closest type strain (97.4 % sequence similarity or less). Chemotaxonomic data, including fatty acid profiles [with the major components C16 : 0 and summed feature 8 (C18 : 1ω6c/C18 : 1ω7c)], the slow growth rate and carbon compound utilization patterns supported the assignment of our strains to the genus Bradyrhizobium . Results from DNA–DNA hybridizations and physiological traits differentiated our strains from the closest related species of the genus Bradyrhizobium with validly published names. Sequences of symbiosis-related genes for nodulation (nodC) and nitrogen fixation (nifH) grouped together with those of B. iriomotense EK05T and Bradyrhizobium sp. strains BR 6610 (used as a commercial inoculant for Inga marginata in Brazil) and TUXTLAS-10 (previously observed in Central America). Based on these data, the six strains represent a novel species, for which the name Bradyrhizobium ingae sp. nov. is proposed. The type strain is BR 10250T ( = HAMBI 3600T).

Two novel strains, designated 92R-1T and 9PBR-1T, were isolated from abandoned lead–zinc ore collected in Meizhou, Guangdong Province, PR China. Phylogenetic analyses based on 16S rRNA gene sequences showed that they fell into the genus of Hymenobacte r and formed two distinct lineages. Strain 92R-1T was most closely related to Hymenobacter wooponensis JCM 19491T (98.7 %) and Hymenobacter gelipurpurascens LMG 21873T (98.5 %), while strain 9PBR-1T was most closely related to Hymenobacter chitinivorans LMG 21951T (99.0 %), Hymenobacter elongatus JCM 17223T (98.7 %) and Hymenobacter aquaticus JCM 31653T (98.1 %). Strain 92R-1Tshared average nucleotide identity values of 80.0–83.7 % and digital DNA–DNA hybridization values of 23.1–27.1 % with its closely related type strains, respectively, while strain 9PBR-1T shared corresponding values of 80.3–83.2 % and 23.6–26.7 % with its closely related type strains, respectively. The two novel strains could be clearly distinguished from their closely related type strains by enzyme activities and substrates assimilation, respectively. Both of them took iso-C15:0, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), summed feature 4 (iso-C17:1 I and/or anteiso-C17:1 B) and C16:1 ω5c as major fatty acids, and showed clear differences from their closely relatives in the contents of several components. They contained menaquinone 7 as the major respiratory quinone and phosphatidylethanolamine as the dominant polar lipid. The G+C contents of strains 92R-1T and 9PBR-1T were 56.7 and 59.5 mol%, respectively. The results clearly supported that strains 92R-1T and 9PBR-1T represent two distinct novel species within the genus Hymenobacter , for which the names Hymenobacter fodinae sp. nov. (type strain 92R-1T=GDMCC 1.1493T=JCM 32697T) and Hymenobacter metallicola sp. nov. (type strain 9PBR-1T=GDMCC 1.1491T=JCM 32698T) are proposed.
