What is Shewanella oneidensis used for?
oneidensis’ ability to reduce and absorb heavy metals makes it a candidate for use in wastewater treatment. DSFO+ could possibly allow the bacteria to electrically communicate with an electrode and generate electricity in a wastewater application.
Where can you find Shewanella oneidensis?
Shewanella oneidensis is a Gram-negative anaerobic bacteria which is predominantly found in deep sea anaerobic habitats; but can also reside in soil and sedentary habitats. There is a presence of lipoproteins/cytochromes (MtrC and OmcA) on the outer membrane of Shewanella oneidensis.
Who discovered Shewanella oneidensis?
Professor Ken Nealson
Shewanella oneidensis was first isolated in 1988 by Professor Ken Nealson from sediments of Lake Oneida in New York. The lake where the bacteria was first discovered accounts for its naming. Sequencing of S. oneidensis’s genome was completed in September , 2002.
How does Shewanella oneidensis produce electricity?
Shewanella keeps calm and carries on producing energy by using metals, like iron and manganese, instead. This scanning electron microscope image shows Shewanella oneidensis MR-1 bacteria. These bacteria are able to generate electric currents that can be conducted along nanowires extending from their cell membranes.
How do you pronounce Shewanella oneidensis?
She·wanel·la onei·den·sis.
Where is geobacter Sulfurreducens found?

How might bacteria help provide energy in the future?
For example, bacteria and other micro-organisms can be used to produce biofuel, in what is known as microbial biofuel cells. Of particular interest in an energy context are the photosynthesising bacteria. If they are attached to an electrode, they can generate electric energy when exposed to light.
Can we use bacteria for energy?
Who discovered Geobacter Sulfurreducens?

What kind of respiration is Shewanella oneidensis Mr 1?
High amounts of reduced manganese in the lake led to the discovery of the Shewanella model species: Shewanella oneidensis MR-1, which transfers electrons to insoluble oxidized manganese as a form of respiration. (Photo from the EPA: http://www.epa.gov/owow/NPS/success/state/ny_chitmap.htm)
How did the Shewanella oneidensis get its name?
After rRNA sequencing, the bacteria was characterized as a Shewanella , and the species was named Shewanella oneidensis MR-1 (“manganese reducer”) after the lake in which it was discovered (Slonczewski et al, 2011).
What kind of nanoparticles can Shewanella oneidensis produce?
Shewanella has been seen in laboratory settings to bioreduce a substantial amount of palladium and dechlorinate near 70% of polychlorinated biphenyls The production of nanoparticles by S. oneidensis MR-1 are closely associated to the MTR pathway (e.g. silver nanoparticles), or the hydrogenase pathway (e.g. palladium nanoparticles).
