Species
Bacteroides fluxus is a newly recognized bacterium that is part of the diverse human gastrointestinal microbiome, and the GI microbiome of some other mammalians. The strain of B. fluxus that was isolated from human feces is known as YIT 12057. The short lived life span of this bacterium during observation led to the nomenclature of B. fluxus.
Description and significance
Bacteroides fluxus is an obligately anaerobic, gram stain negative cell that is non-motile, non-spore forming, and rod shaped, measuring 1.0 – 1.4 μm wide and 1.0 – 2.5 μm long. The major fatty acids that make up B. fluxus are anteiso-C15: 0, summed feature 11 (comprising iso-C17: 0 3-OH and/or C18: 2 dimethylacetal), C18: 1ω9c and iso-C15: 0 and the primary respiratory quinones are Mk-10 and Mk-11. The guanine-cytosine content is 45.2 mol%. The 16s rRNA gene sequence of B. fluxus is a 95.0% match to B. uniformis. B. fluxus incubated on GAM agar appear as opaque, whitish gray, circular and domed colonies with butter like texture and a shiny sheen.
