Comparability from the sexual penetration detail of five actual channel sealers: A confocal laser beam checking minute review.
A Gram-stain-negative, aerobic, asporogenous, motile by gliding, dull-yellow, long rod-shaped bacterial strain, designated SNL9T, was isolated from a flooded paddy field near Dongguk University, Republic of Korea. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that SNL9T represents a member of the genus Flavobacterium and is most closely related to Flavobacterium ummariense DS-12T (96.2%) and Flavobacterium viscosum YIM 102796T (96.3%). The average nucleotide identity and in silico DNA-DNA hybridization (DDH) values with F. ummariense DS-12T and F. viscosum YIM 102796T were 89.3/39.1 and 87.1/33 %, respectively. The major fatty acids of SNL9T were identified as iso-C15  0, summed feature 3 (comprising C16    1ω6c and/or C16    1ω7c) and summed feature 9 (comprising iso-C17  1ω9c and/or 10 methyl C16  0). SNL9T contained MK-6 as the major respiratory quinone. The polar lipids were phoshatidylethanolamine, one unidentified aminophosphoglycolipid, three unidentified aminoglycolippe is SNL9T (=KACC 21170T=NBRC 113746T).Strains of the genus Bradyrhizobium associated with agronomically important crops such as soybean (Glycine max) are increasingly studied; however, information about symbionts of wild Glycine species is scarce. Australia is a genetic centre of wild Glycine species and we performed a polyphasic analysis of three Bradyrhizobium strains-CNPSo 4010T, CNPSo 4016T, and CNPSo 4019T-trapped from Western Australian soils with Glycine clandestina, Glycine tabacina and Glycine max, respectively. The phylogenetic tree of the 16S rRNA gene clustered all strains into the Bradyrhizobium japonicum superclade; strains CNPSo 4010T and CNPSo 4016T had Bradyrhizobium yuanmingense CCBAU 10071T as the closest species, whereas strain CNPSo 4019T was closer to Bradyrhizobium liaoningense LMG 18230T. The multilocus sequence analysis (MLSA) with five housekeeping genes-dnaK, glnII, gyrB, recA and rpoB-confirmed the same clusters as the 16S rRNA phylogeny, but indicated low similarity to described species, with nucleotide identities ranging from 93.6 to 97.6% of similarity. Considering the genomes of the three strains, the average nucleotide identity and digital DNA-DNA hybridization values were lower than 94.97 and 59.80 %, respectively, with the closest species. In the nodC phylogeny, strains CNPSo 4010T and CNPSo 4019T grouped with Bradyrhizobium zhanjiangense and Bradyrhizobium ganzhouense, respectively, while strain CNPSo 4016T was positioned separately from the all symbiotic Bradyrhizobium species. Other genomic (BOX-PCR), phenotypic and symbiotic properties were evaluated and corroborated with the description of three new lineages of Bradyrhizobium. We propose the names of Bradyrhizobium agreste sp. nov. for CNPSo 4010T (=WSM 4802T=LMG 31645T) isolated from Glycine clandestina, Bradyrhizobium glycinis sp. nov. for CNPSo 4016T (=WSM 4801T=LMG 31649T) isolated from Glycine tabacina and Bradyrhizobium diversitatis sp. nov. for CNPSo 4019T (=WSM 4799T=LMG 31650T) isolated from G. max.A novel member of the actinobacteria, designated strain A-T 0013T, was isolated from humic soil on a bird's nest fern (Asplenium nidus L.) collected from Khao Yai National Park in Thailand. According the results of a polyphasic taxonomic study, A-T 0013T had characteristics typical of members of the genus Gordonia. The 16S rRNA gene sequence indicated that A-T 0013T shared ≤98 % sequence similarity with all members of the genus Gordonia. The most closely related species was Gordonia effusa IFM 10200T (97.92 % sequence similarity). The average nucleotide identity based on blast (ANIb) value with G. Lanifibranor order effusa IFM 10200T was 76.81 %. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars contained ribose, arabinose and galactose. The predominant menaquinone was MK-9(H2). The predominant fatty acids were C16  0, C18  1ω9c, summed feature 3 (C16  1ω7c/C16  1ω6c), and C18  0 10-methyl. Mycolic acid was present. The polar lipid profile for this strain ncluded diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides. The G+C content of the genomic DNA was 66.1 mol%. Differentiation of A-T 0013T from the most closely related species, Gordonia effusa IFM 10200T, was evident from digital DNA-DNA hybridization values of 21.8 %. On the basis of the results of comparative analysis of phenotypic, chemotaxonomic and genotypic data, strain A-T 0013T is concluded to represent a novel species of the genus Gordonia, for which the name Gordonia asplenii sp. nov. is proposed. The type strain is A-T 0013T (=TBRC 11910T=NBRC 114549T).A novel aerobic bacterial strain, designated MK012T, was isolated from the phycosphere of Microcystis aeruginosa. MK012T appears to be Gram-stain-negative, non-motile and rod-shaped and has yellow pigments. Phylogenetic analysis using 16S rRNA revealed that this bacterium was most closely related to Flavobacterium buctense T7T (=JCM 30750T; 97.5 %), Flavobacterium dankookense ARSA-19T (=KCTC 23179T; 97.5 %) and Flavobacterium macrobrachii an-8T (=DSM 22219T; 97.3 %). The genome size and genomic DNA G+C content of MK012T were estimated at 3.3 Mbp and 37.6 mol%, respectively. The average nucleotide identity (ANI), average amino acid identity (AAI) and in silico DNA-DNA hybridization (dDDH) values of MK012T and the members of the genus Flavobacterium were found to be 71.8-78.3 %, 65.1-79.6% and 19.1-21.5 %, respectively. MK012T exhibited oxidase but no catalase activity. The cells grew at 14-36 °C (optimum, 25 °C), pH 5-10 (optimum, pH 7) and 0-0.4 % (w/v) NaCl (optimum, 0 % NaCl) in R2A medium. MK012T did not produce flexirubin-type pigments. The predominant cellular fatty acids of MK012T were determined to be iso-C15  0, iso-C15  0 3-OH, iso-C17  0 3-OH, and summed feature 9 (10-methyl C16  0 and/or iso-C17  1ω9c); MK-6 was identified as its only respiratory quinone. Its major polar lipids were determined to be phosphatidylethanolamine, two unidentified aminolipids, and two unidentified polar lipids. The genotypic and phenotypic characteristics indicate that MK012T (=KACC 21509T=JCM 33879T) represents a novel species of the genus Flavobacterium; therefore, the name Flavobacterium phycosphaerae sp. nov. is proposed.
