Geobacter
''Geobacter'' is a genus of bacteria. ''Geobacter'' species are anaerobic respiration bacterial species which have capabilities that make them useful in bioremediation. ''Geobacter'' was found to be the first organism with the ability to oxidize organic compounds and metals, including iron, radioactive metals, and petroleum compounds into environmentally benign carbon dioxide while using iron oxide or other available metals as electron acceptors. ''Geobacter'' species are also found to be able to respire upon a graphite electrode. They have been found in anaerobic conditions in soils and aquatic sediment. History '' Geobacter metallireducens'' was first isolated by Derek Lovley in 1987 in sand sediment from the Potomac River in Washington D.C. The first strain was deemed strain GS-15. Metabolic mechanisms For quite some time, it was thought that ''Geobacter'' species lacked c-cytochromes that can be utilized to reduce metal ions, hence it was assumed that they required d ...

Geobacter Sulfurreducens
''Geobacter sulfurreducens'' is a gram-negative metal and sulphur-reducing proteobacterium. It is rod-shaped, obligately anaerobic, non-fermentative, has flagellum and type four pili, and is closely related to '' Geobacter metallireducens''. ''Geobacter sulfurreducens'' is an anaerobic species of bacteria that comes from the family of bacteria called Geobacteraceae. Under the genus of Geobacter, ''G. sulfurreducens'' is one out of twenty different species. The Geobacter genus was discovered by Derek R. Lovley in 1987. ''G. sulfurreducens'' was first isolated in Norman, Oklahoma, USA from materials found around the surface of a contaminated ditch. Characteristics ''Geobacter sulfurreducens'' is a rod-shaped microbe with a gram-negative cell wall. Geobacter is known as a type of bacteria that is able to conduct levels of electricity, and the species ''G. sulfurreducens'' is also known as “electricigens” due to their ability to create an electric current and produce electri ...

Geobacter Metallireducens
''Geobacter metallireducens'' is a gram-negative metal-reducing proteobacterium. It is a strict anaerobe that oxidizes several short-chain fatty acids, alcohols, and monoaromatic compounds with Fe(III) as the sole electron acceptor. It can also use uranium for its growth and convert U(VI) to U(IV). ''Geobacter metallireducens'' was discovered by Derek Lovley at UMass Amherst in 1993. It is an iron-reducing bacteria and it has been thought that the microbe could be used to treat industrial sites where "cyanide-metal complexes" have formed to contaminate the site. ''Geobacter metallireducens'' becomes motile when necessary, producing a flagellum in order to relocate when environmental conditions become unfavorable. The genome of ''Geobacter metallireducens'' has a chromosome length of 3,997,420 bp. It has a circular bacterial chromosome, meaning there are no free ends of DNA. The shape is roughly like that of an egg. ''Geobacter metallireducens'' also has a GC content of 59.51 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geobacter Uraniireducens
''Geobacter uraniireducens'' (more recently known as ''Geotalea uraniireducens'') is a gram-negative, rod-shaped, anaerobicchemolithotrophic mesophilic, and motile bacterium from the genus of ''Geobacter''. G. ''uraniireducens'' has been found to reduce iron and uranium in sediment and soil. It is being studied for use in bioremediation projects due to its ability to reduce uranium and arsenic. History ''Geobacter uraniireducens'' was isolated from the subsurface sediment of a previous uranium ore processing facility undergoing uranium bioremediation in 2002. This occurred during a field study by Robert Anderson and his associates at the Old Rifle in situ test plot area in Rifle, Colorado. Shelobolina et al. (2008) further described the strain Rf4T While ''Geobacter uraniireducens'' is the basonym, David Waite and associates reclassified it to the current preferred name, ''Geotalea uraniireducens'' in their 2020 paper. Characteristics ''G. uraniireducens'' are gram negative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geobacter Anodireducens
''Geobacter anodireducens'' is a Gram-negative, aerotolerant, exoelectrogenic, anaerobic, non-spore-forming and non-motile bacterium from the genus of ''Geobacter'' Like others in its genus, it is commonly found in soil and uses iron as its electron acceptor. Due to its ability to generate current, it is an organism of note for Microbial fuel cell research. ''G. anodireducens'' was first isolated in 2014, and characterized in 2019, both by Dan Sun. Characteristics ''G. anodireducens'' is curved bacillus, most easily distinguished from its cousins Geobacter metallireducens and Geobacter sulfurreducens ''Geobacter sulfurreducens'' is a gram-negative metal and sulphur-reducing proteobacterium. It is rod-shaped, obligately anaerobic, non-fermentative, has flagellum and type four pili, and is closely related to ''Geobacter metallireducens''.
