Brachybacterium muris is a species of Gram positive, strictly aerobic, yellow-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from the liver of a laboratory mouse. The species was first described in 2003, and the name is derived from the Latin muris (mouse).
Brachybacterium phenoliresistens is a species of Gram positive, facultatively anaerobic, yellow-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from oil-contaminated sand in Pingtung County, Taiwan. The species was first described in 2007, and its name refers to the species' ability to resist phenol. It is most closely related to B. nesterenkovii.
Brachybacterium sacelli is a species of Gram positive, strictly aerobic, cream-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from a medieval wall painting of the chapel of Schloss Herberstein in Styria, Austria. The species was proposed in 2014, and the name is derived from Latin sacelli. Another novel species B. fresconis was isolated from the same painting.
