Roseomonas rosea (formerly Muricoccus roseus) is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pink-colored bacteria.
[1] Further work on the isolate led to the proposal of a new genus and species, Muricoccus roseus in 2003.
[2] Further work on M. roseus found that the species belonged in the genus Roseomonas, and also led to Teichococcus ludipueritiae being reclassified as Roseomonas ludipueritiae in 2009.
[3] The species name is derived from Latin rosea (pink), referring to the pink color the bacterial colonies will form, which is also a present in most Roseomonas species.
The optimum growth temperature for R. rosea is 30 °C, but can grow in the 15-45 °C range.
