A Gram-stain-positive, slightly halophilic, endospore-forming, strictly aerobic, rod-shaped bacterium, designated SKP7-4T , was isolated from shrimp paste collected from Samut Sakhon province, Thailand. Strain SKP7-4T grew at pH 6.0-9.0 (optimum, 7.5), at 20-40 °C (37 °C) and in 0-15 % (w/v) NaCl (1-3 %). The diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid. Menaquinone with seven isoprene units was the major isoprenoid quinone. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unidentified phospholipids were detected as polar lipids...

A novel Gram-stain-positive, non-motile, non-spore-forming coccus-shaped obligately anaerobic bacterium was recovered from a fecal sample obtained from an individual from a traditional community located on the southern coast of Peru. The results of analysis based on 16S rRNA gene sequencing indicated the novel bacterium to be phylogenetically distinct from other genera of members of the Peptoniphilaceae family, sharing a loose affinity with the genera Ezakiella, Finegoldia, Gallicola and Parvimonas. The major cellular fatty acids of the novel isolate were determined to be C16:0, C17:1ω8c, and C18:1ω9c...

In this study, we propose a new genus, Victoriomyces, with a new species, Victoriomyces antarcticus, isolated from soil samples collected in Victoria Land, Antarctica. To determine its taxonomic status and evolutionary relationships, phylogenetic analysis was performed on DNA sequences from the nuclear 18S rRNA, 28S rRNA and the second largest subunit of RNA polymerase II (RPB2) genes. Victoriomyces antarcticus constitutes one well-supported distinct lineage within the Cephalothecaceae (family incertae sedis in Sordariomycetes), in which the only recognised asexual morphs belong to the genus Phialemonium and to Acremonium thermophilum...

A Gram-stain-negative, rod-shaped, motile bacterial strain, designated 3-5-3T , was isolated from maize-cultivated soil artificially contaminated with cadmium, in Nanyang, Henan Province, China. Strain 3-5-3T was oxidase- and catalase-positive. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 3-5-3T was affiliated with the genus Paenibacillus and most closely related to Paenibacillus anaericanus MH2T (96.5 % similarity). The average nucleotide identity and digital DNA-DNA hybridization values between 3-5-3T and the closely related species ranged 69...

In 2016, division of the genus Propionibacterium into four distinct genera was proposed. As a consequence, the species Propionibacterium acnes was transferred to Cutibacterium gen. nov. as Cutibacterium acnes comb. nov. The three recently proposed subspecies of P. acnes were not, however, accommodated in this proposal. Following a very recent validation of a new combination for C. acnessubsp.defendens and an automatically created C. acnessubsp.acnes, we now propose the new combination, C. acnessubsp. elongatum comb...

Previous analyses based on 16S rRNA and hsp60 genes indicated that Parolsenella catena and Libanicoccus massiliensis were closely related to each other and formed a monophyletic cluster independent of the related Olsenella species. To clarify the relationship of these two species, we determined the genome sequence of P. catena JCM 31932T and compared it with that already sequenced for L. massiliensis Marseille-P3237T . Phylogenetic trees based on the concatenated 37 single-copy ribosomal proteins or RpoB robustly supported the relationship observed in the previous studies...

Strains 449T and 622 are both aerobic, Gram-stain-positive, short, rod-shaped bacilli that were recently isolated from the faeces of Tibetan antelopes on the Qinghai-Tibet Plateau in China. Their 16S rRNA gene sequences were most similar to those of Mycetocola zhadangensis ZD1-4T (97.9-98.0 %) and Mycetocola miduiensis CGMCC 1.11101T (97.3-97.4 %). Phylogenetic analysis of the 16S rRNA gene sequences further suggested that strains 449T and 622 represent a new lineage within the genus Mycetocola. The G+C content of strain 449T is 64...
