Six clinical isolates of a hitherto unknown, strictly anaerobic, Gram-negative rod showing fastidious growth were subjected to a polyphasic taxonomic study, including phenotypic, genomic and phylogenetic feature analyses. 16S rRNA gene sequenced-based phylogeny revealed that the novel strains represent a homogeneous group distant from any recognized species in the candidate phylum 'Synergistetes'. The novel isolates were most closely related to species of the genus Dethiosulfovibrio, with 88.2-88.7 % 16S rRNA gene sequence similarity. Large-scale chromosome structure and DNA G+C content also differentiated the novel strains from members of the genus Dethiosulfovibrio. The novel strains were asaccharolytic. Major metabolic end products in trypticase/glucose/yeast extract broth were acetic, lactic, succinic and isovaleric acids and the major cellular fatty acids iso-C(15 : 0) and C(16 : 0). Based on the data presented here, a new genus, Jonquetella gen. nov., is proposed with one novel species, Jonquetella anthropi sp. nov. J. anthropi is the first characterized species of the candidate phylum 'Synergistetes' that includes human isolates. The G+C content of the DNA of the type strain of J. anthropi ADV 126(T) (=AIP 136.05(T)=CIP 109408(T)=CCUG 53819(T)) is 59.4 mol%.

Effects of Long-Term Fasting on Gut Microbiota, Serum Metabolome, and Their Association in Male Adults.

Background: Long-term fasting demonstrates greater therapeutic potential and broader application prospects in extreme environments than intermittent fasting.
Method: This pilot study of 10-day complete fasting (CF), with a small sample size of 13 volunteers, aimed to investigate the time-series impacts on gut microbiome, serum metabolome, and their interrelationships with biochemical indices.
Results: The results show CF significantly affected gut microbiota diversity, composition, and interspecies interactions, characterized by an expansion of the Proteobacteria phylum (about six-fold) and a decrease in Bacteroidetes (about 50%) and Firmicutes (about 34%) populations.

Oilseed rape is one of the most important oilseed crops, requiring high levels of nitrogen fertilization. Excessive nitrogen use, however, leads to numerous negative environmental impacts, spurring the search for sustainable, environmentally friendly alternatives to reduce reliance on mineral nitrogen fertilizers. One promising approach involves plant-growth-promoting bacteria (PGPB), which can support oilseed rape growth and lessen the need for traditional nitrogen fertilizers.

Primary open-angle glaucoma (POAG) is the most common form of glaucoma. This condition leads to optic nerve degeneration and eventually to blindness. Tobacco smoking, alcohol consumption, fast-food diets, obesity, heavy weight lifting, high-intensity physical exercises, and many other bad habits are lifestyle-related risk factors for POAG.

Background: While the relationship between gut microbiota and gastrointestinal cancer has been elucidated, the relationship between lung microbiota and lung cancer remains unclear. Previous study findings are inconclusive due to the possibility of contamination by upper airway microbiota in samples obtained from the oropharynx, such as saliva and sputum, and bronchoalveolar lavage fluid (BALF) collected during bronchoscopy. Therefore, this study aimed to detect pure lung microbiota in patients with lung cancer using BALF samples from resected lung specimens.
