Description and significance

Shewanella woodyi is a gram negative bacilli shaped bacterium between 1 to 2 micrometers in length. It is entirely marine and can be found in deep-sea environments therefore making it barophilic (tolerant to high pressure). Although other species within the Shewanella genus are psychrophilic, S. woodyi is instead mesophilic growing at an optimal temperature around 25°C. Each S. woodyi bacterial cell possesses a single polar flagellum making it motile, as seen in Figure ______. This bacterium is also luminescent, meaning it can emit light.

It is well known that the ocean acts as a sink for harmful compounds from both terrestrial and aquatic environments. S. woodyi is significant in that it helps reduce the levels of select toxic compounds such as RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine). Additionally, this bacterium also plays a role in carbon and nitrogen cycling through its anaerobic capabilities.
