Two novel anaerobic, mesophilic, bio-hydrogen producing bacteria, designated strains ZGM211T and G1T, were isolated from lake sediment. 16S rRNA and ATP synthase beta subunit (atpD) gene sequences phylogenetic analysis of strains ZGM211T and G1T revealed an affiliation to the genus Clostridium sensu stricto (cluster I of the clostridia), with Clostridium acetobutylicum as the closest characterized species, showing the same sequence similarity of 96.4% to the type strain (98.9% between the two isolates). Cells of the two strains were rod-shaped...

A Gram-negative, aerobic, yellow-pigmented, non-flagellated, non-gliding, oxidase- and catalase- positive bacterium, designated CY01T, was isolated from seawater of the Yellow Sea. Strain CY01T grew at 15-37 C (optimum, 30 C), at pH 5-8 (optimum, 6.5-7.5) and with 0.5-12 % (w/v) NaCl (optimum, 0.5-3.5 %). It could not produce flexirubin-type pigment or reduce nitrate to nitrite. Strain CY01T showed the highest 16S rRNA gene sequence similarity to type strain of Euzebyella saccharophila (97.0 %) and clustered tightly with the Euzebyella species in the phylogenetic trees based on the 16S rRNA gene sequences...

One hundred and ninety-eight isolates of soil yeasts were isolated from mixed temperate forests in the Czech Republic, and their abundance and distribution in the litter and soil were evaluated using amplicon sequencing of soil fungal communities. Abundant taxa with no close identified hits were selected for further characterization as potential novel species of yeasts. Phylogenetic analyses using sequences of the D1/D2 domains, the ITS region and RPB1 and TEF1 genes support the recognition of the following three new species belonging to the subphylum Pucciniomycotina, class Microbotryomycetes: Leucosporidium krtinense f...

Aharon Oren
According to the current version of Rule 12c of the International Code of Nomenclature of Prokaryotes, one of the ways in which a specific epithet can be treated is as an adjective that must agree in gender with the generic name. I propose emending this part of Rule 12c to specify that such adjectives must be in the singular form in the nominative case.

Seven isolates recovered from diseased fine flounders (Paralichthys adspersus) and red conger eel (Genypterus chilensis) experimentally reared in Quintay (Chile) were confirmed as V. tapetis on the basis of the MALDI-TOF MS, 16S rRNA gene, DNA-DNA hybridization values and G+C content. The ERIC-PCR and REP-PCR patterns were homogeneous among those isolates recovered from a same host, but distinct to the type strains V. tapetis subsp. tapetis CECT 4600T and V. tapetis subsp. britannicus CECT 8161T. On the basis of atpA, rpoA, rpoD, recA and pyrH gene similarities (99...

The strain KT0803T was isolated from coastal eutrophic surface waters of Helgoland Roads near the island of Helgoland, North Sea, Germany. The taxonomic position of the strain, previously known as 'Gramella forsetii' KT0803, was investigated by a polyphasic approach. The strain was Gram-stain negative, chemo-organotrophic, heterotrophic, strictly aerobic, oxidase and catalase positive, rod-shaped, motile by gliding and had orange-yellow carotenoid pigments, but was negative for flexirubin-type pigments. It grew optimally at 22-25 °C, pH 7...

The bacterial strain 2-92T isolated from a field plot under long-term (>40 years) mineral fertilization exhibited in vitro antagonistic properties against fungal pathogens. A polyphasic approach was undertaken to verify its taxonomic status. Strain 2-92T is gram-negative, aerobic, non-spore-forming, motile by one or more flagella, and oxidase-, catalase- and urease-positive. Optimal growth temperature of strain 2-92T is 30 °C. 16S rRNA gene sequence analysis demonstrated that the strain is related to species of the genus Pseudomonas...

Acidobacteria represent one of the highly diverse but poorly characterized phylogenetic groups of the domain Bacteria. The taxonomically described acidobacteria belong to 27 genera and 49 species, which represent subdivisions 1, 3, 4, 6, 8, 10 and 23 of this phylum. However, the corresponding family ranks have been defined only for some of these characterized microorganisms. Here, we suggest the establishment of a novel family, Bryobacteraceae fam. nov., to accommodate taxonomically described members of subdivision 3 Acidobacteria...
