A bright-yellow, Gram-stain-negative, rod-shaped, gliding and aerobic bacterium, designated strain AQ6-291T, was isolated from the Fildes Peninsula, Antarctica, and its taxonomic position was investigated by genotypic, phenotypic and chemotaxonomic analyses. Growth occurred at 4-28 °C (optimum 20 °C) and at pH 5.0-8.0 (optimum pH 7.0). Strain AQ6-291T contained iso-C15 : 1 G, iso-C15 : 0, C16 : 1ω5c, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) as the major cellular fatty acids...

A Gram-stain-negative, obligatory anaerobic spirochete, CHPAT, was isolated from the rectal tissue of a Holstein-Friesian cow. On the basis of 16S rRNA gene comparisons, CHPAT was most closely related to the human oral spirochete, Treponema parvum, with 88.8 % sequence identity. Further characterisation on the basis of recA gene sequence analysis, cell morphology, pattern of growth and physiological profiling identified marked differences with respect to other recognised species of the genus Treponema. Microscopically, the helical cells measured approximately 1-5 µm long and 0...

Three strains representing a novel species of the Ogataea clade were isolated by W. T. Starmer and H. J. Phaff from rotting tissue of Opuntia phaeacantha in Arizona, USA. Analyses of the sequences of the D1/D2 LSU rRNA gene, ITS1-5.8S-ITS2, and translation elongation factor-1α (EF-1 α) showed that this novel species belongs to the Ogataea polymorpha complex formed by Ogataea angusta, Ogataea parapolymorpha and Ogataea polymorpha. The novel species differs from these species by 4-5 nucleotide substitutions in the D1/D2 domain, by 28-29 nucleotide substitutions in the EF-α gene and by 18-24 nucleotide substitutions and 2-5 indels in the ITS-5...

A facultatively anaerobic, endospore forming, alkali-tolerant, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK61T, was isolated from a sediment sample collected from Coringa mangrove forest, India. Colonies were circular, 1.5 mm in diameter, shiny, smooth, yellowish and convex with entire margins after 48 h growth at 30 °C. Growth occurred at 15-42 °C, with 0-3 % (w/v) NaCl and at pH 6-9. AK61T was positive for amylase activity and negative for oxidase, catalase, aesculinase, caseinase, cellulase, DNase, gelatinase, lipase and urease activities...

Two Gram-stain-positive, aerobic, pink, curved, rod-shaped, non-motile bacterial strains, designated MI-28T and SKY-11, were isolated from freshwater samples taken from a river and fish pond, respectively. Based on characterization using a polyphasic approach, the two strains showed highly similar phenotypic, physiological and genetic profiles. They demonstrated 99.9 % 16S rRNA gene sequence similarity and a 93-95 % DNA-DNA relatedness value, suggesting that they represent a single genomic species. Phylogenetic analyses, based on 16S rRNA gene sequences, showed that strains MI-28T and SKY-11 form a distinct lineage with respect to closely related genera within the family Microbacteriaceae of the class Actinobacteria, which is most closely related to Rhodoluna and Pontimonas, and levels of 16S rRNA gene sequence similarity with the type species of related genera were less than 95 %...

Three light-brown-coloured, Gram-stain-negative, small rod- to oval-shaped, motile bacteria were isolated from lagoon sediments collected from North Carolina, USA. The strains (S1T, AS3 and AS6) grew aerobically at 13-42 °C (optimum, 30-35 °C) and pH 6.5-9.1 (optimum, pH 7.0-7.5). All three strains were positive for catalase and oxidase activity, and no added NaCl was required for growth. C18 : 1ω6c/C18 : 1ω7c, C16 : 1ω6c/C16 : 1ω7c, C18 : 1ω7c 11-methyl and C16 : 0 were the predominant fatty acids (>5 %)...

Fresh samples of intestinal contents of three wild pigs originating from the Central Bohemia region were examined for the presence of bifidobacterial strains. During the study, we isolated many fructose-6-phosphate phosphoketolase-positive, strictly anaerobic, irregular rod-shaped bacterial isolates. Three of them were preliminarily identified as representing a novel species of the genus Bifidobacterium because their 16S rRNA gene sequence similarity with the closest relatives of thermophilic bifidobacteria (Bifidobacterium boum DSM 20432T, Bifidobacterium thermophilum DSM 20210T, Bifidobacterium thermacidophilumsubsp...

A taxonomic study was conducted on strain soj2014T, which was isolated from the surface water of a polynya in the Antarctic Sea. Comparative 16S rRNA gene sequence analysis showed that strain soj2014T belongs to the family Kiloniellaceae and is closely related to Kiloniella spongiae MEBiC09566T, 'Kiloniella litopenaei' P1-1T and Kiloniella laminariae LD81T (98.0 %, 97.8 % and 96.2 % 16S rRNA gene sequence similarity, respectively).

A Gram-reaction-negative, aerobic, oxidase- and catalase-positive, yellow-pigmented, non-flagellated, rod-shaped bacterium, designed strain SM1501T, was isolated from surface seawater of the South China Sea. SM1501T grew at 7-42 °C and with 0-11 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that SM1501T represented a member of the genus Erythrobacter, sharing the highest 16S rRNA gene sequence similarity (97.4 %) with Erythrobacter luteus and 94.2-96.5 % 16S rRNA gene sequence similarities to other species of the genus Erythrobacterwith validly published names...

Strain N5SSJ16T, a Gram-negative-staining, non-spore-forming, rod-shaped, non-motile bacterium, was isolated from Haloxylon ammodendron stems. The strain grew in the presence of 0-4 % (w/v) NaCl (optimum growth in the absence of NaCl), at pH 7-9 (optimum: pH 8) and at 12-50 °C. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain N5SSJ16T was related phylogenetically to Parapedobacter composti 4M40T (96.5 %) and Parapedobacter luteus 4M29T (95.9 %). The cellular fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), summed feature 9 (C16 : 0 10-methyl and/or iso-C17 : 1ω9c) and iso-C17 : 0 3-OH...

A novel Gram-stain-negative, aerobic and rod-shaped marine bacterium, designated strain HMF4135T, was isolated from a sand sample which was collected from the seashore of the South Sea, Republic of Korea. It required NaCl for growth and exhibited optimal growth at 30 °C, with 2 % (w/v) NaCl and at pH 7-8. Cellular fatty acids were dominated by C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 1ω9c and C12 : 0 3-OH. The predominant isoprenoid quinone was ubiquinone-8 (Q-8)...

We herein report the isolation and characterization of 21 Gram-stain-negative strains cultivated from the oropharynx of healthy children in Israel and Switzerland. Initially described as small colony variants of Kingella kingae, phenotypic analysis, biochemical analysis, phylogenetic analysis based on sequencing of the partial 16S rRNA gene and five housekeeping genes (abcZ, adk, G6PD, groEL and recA), and whole genome sequencing and comparison between members of the genera Kingella and Neisseria provided evidence for assigning them to the genus Kingella...

A Gram-stain-negative, facultatively anaerobic coccobacilli approximately 0.4-0.5×0.5-1.1 µm, non-motile, orange-pigmented bacterial strain, designated am2T, was isolated from the coastal area of Weihai, PR China (121° 57' E, 37° 29' N). The temperature, pH and NaCl ranges for growth were 4-40 °C, pH 6.5-8.5 and 0.0-6.0 % (w/v) NaCl. The results of phylogenetic analyses based on 16S rRNA gene sequences revealed that am2T was phylogenetically related to members of the genus Algoriphagus and was closely related to Algoriphagus boritolerans, Algoriphagus namhaensis and Algoriphagus antarcticus with 96...

A bacterial strain designated CRZM18RT was isolated from a root of Zea mays in Spain. The analysis of the 16S rRNA gene sequence showed that this strain belongs to the genus Rhizobium, with Rhizobium cellulosilyticum ALA10B2T and Rhizobium yantingense H66T being the most closely related species with 98.3 and 97.9 % sequence similarity, respectively. The analysis of the concatenated recA and atpD genes showed that strain CRZM18RT forms a cluster with these species and also with Rhizobiumsmilacinae PTYR-5T, but the recA and atpD genes of strain CRZM18RT were phylogenetically distant, with identities lower than 90 and 96 %, respectively...
