Becquerelleilla

Becquerelleilla is a genus of gram-negative, obligately anaerobic bacteria belonging to the family Tannerellaceae. First described in 2017, the genus currently contains a single species, Becquerelleilla tructa. These bacteria are typically found in the gastrointestinal tract of vertebrates, with initial isolation from the cecum of rainbow trout (Oncorhynchus mykiss).

Morphologically, Becquerelleilla are rod-shaped and motile. They are chemoorganotrophic and exhibit fermentation as their primary mode of energy production. Their metabolic capabilities include the breakdown of carbohydrates. Research into Becquerelleilla has focused on understanding its role in the gut microbiome of its host.

The classification of Becquerelleilla within the Tannerellaceae family places it alongside other genera known to inhabit the intestinal environment. Phylogenetic analysis based on 16S rRNA gene sequences has been crucial in establishing its distinct taxonomic position. Further research is ongoing to explore the ecological significance and potential interactions of Becquerelleilla with other members of the host's microbiota.
