Roseateles depolymerans is an aerobic photosynthetic bacterium from the genus Roseateles, which was isolated from river water (Hanamuro River, Tsukuba, Japan).
R. depolymerans is a bacteriochlorophyll a-containing obligate aerobe in the β-subclass of the Proteobacteria. The cells are motile, straight rods, and they contain poly-β-hydroxybutyrate granules.
R. depolymerans is characterised by the ability to biodegrade the material poly(hexamethylene carbonate) (PHC), and some other biodegradable plastics.[1]
