geobacter anodireducens 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. geobacter anodireducens scientific classification domain: bacteria phylum: thermodesulfobacteriota class: desulfuromonadia order: geobacterales family: geobacteraceae genus: geobacter species: g. anodireducens binomial name geobacter anodireducenssun et al. 2014 type strain cgmcc 1.12536, sd-1, kctc 4672 synonyms geobacter anodereducens characteristics g. anodireducens is curved bacillus, most easily distinguished from its cousins geobacter metallireducens and geobacter sulfurreducens by its osmotolerance: it is able to withstand nearly twice the salt concentration in solution. genome the genome of g. anodireducens is 3,555,507 base pairs long. the bacteria also contains a plasmid at 110,507 base pairs long. both are circular. a total of 3,564 genes have been located on the plasmid and genome combined.
