The Firmicutes are a phylum of bacteria, most of which have gram-positive cell wall structure. A few, however, such as Megasphaera, Pectinatus, Selenomonas and Zymophilus, have a porous pseudo-outer membrane that causes them to stain gram-negative. Scientists once classified the Firmicutes to include all gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G+C group, in contrast to the Actinobacteria. They have round cells, called cocci, or rod-like forms (bacillus).
A microbial fuel cell (MFC) is a bio-electrochemical system that drives an electric current by using bacteria and a high-energy oxidant such as O2, mimicking bacterial interactions found in nature. MFCs can be grouped into two general categories: mediated and unmediated. The first MFCs, demonstrated in the early 20th century, used a mediator: a chemical that transfers electrons from the bacteria in the cell to the anode. Unmediated MFCs emerged in the 1970s; in this type of MFC the bacteria typically have electrochemically active redox proteins such as cytochromes on their outer membrane that can transfer electrons directly to the anode. In the 21st century MFCs have started to find commercial use in wastewater treatment.
Shewanella is the sole genus included in the marine bacteria family Shewanellaceae. Some species within it were formerly classed as Alteromonas. Shewanella consists of facultatively anaerobic Gram-negative rods, most of which are found in extreme aquatic habitats where the temperature is very low and the pressure is very high. Shewanella bacteria are a normal component of the surface flora of fish and are implicated in fish spoilage.
Thauera is a genus of Gram-negative bacteria in the family Zoogloeaceae of the order Rhodocyclales of the Betaproteobacteria. The genus is named for the German microbiologist Rudolf Thauer. Most species of this genus are motile by flagella and are mostly rod-shaped. The species occur in wet soil and polluted freshwater.
Thauera butanivorans is a species of Gram-negative proteobacteria capable of growth on alkanes C2-C9, but not methane, as well as other organic substrates such as lactate, acetate, succinate and citrate. To grow on alkanes, this bacterium expresses a soluble di-iron monooxygenase closely related to soluble methane monooxygenase from methanotrophs.
Mariprofundus ferrooxydans is a neutrophilic, chemolithotrophic, Gram-negative bacterium which can grow by oxidising ferrous to ferric iron. It is one of the few members of the class Zetaproteobacteria in the phylum Proteobacteria.
Akkermansia is a genus in the phylum Verrucomicrobia (Bacteria). The genus was first proposed in 2004 by Muriel Derrien and others, with the type species Akkermansia muciniphila.
Deferribacter thermophilus is an iron-reducing bacteria. It is a manganese- and iron-reducing bacterium. It is thermophilic and anaerobic bacterium, its type strain being designated as strain BMAT. The cells are straight to bent rods.
Thauera linaloolentis is a gram-negative, mesophilic, motile bacterium from the genus of Thauera.
Thauera mechernichensis is a bacterium from the genus of Thauera which was isolated from a landfill leachate treatment plant.
Thauera selenatis is a gram-negative rod-shaped motile bacterium from the genus of Thauera with a single polar flagellum. Thauera selenatis has the ability to generate energy by respiring anaerobically with the enzyme selenate reductase.
Thauera terpenica is a gram-negative mesophilic motile bacterium from the genus of Thauera.
Geopsychrobacter electrodiphilus is a species of bacteria, the type species of its genus. It is a psychrotolerant member of its family, capable of attaching to the anodes of sediment fuel cells and harvesting electricity by oxidation of organic compounds to carbon dioxide and transferring the electrons to the anode.
Rhodoferax is a genus of Betaproteobacteria belonging to the purple nonsulfur bacteriarophic. Originally, Rhodoferax species were included in the genus Rhodocyclus as the Rhodocyclus gelatinous-like group. The genus Rhodoferax was first proposed in 1991 to accommodate the taxonomic and phylogenetic discrepancies arising from its inclusion in the genus Rhodocyclus. Rhodoferax currently comprises four described species: R. fermentans, R. antarcticus, R. ferrireducens, and R. saidenbachensis. R. ferrireducens, lacks the typical phototrophic character common to two other Rhodoferax species. This difference has led researchers to propose the creation of a new genus, Albidoferax, to accommodate this divergent species. The genus name was later corrected to Albidiferax. Based on geno- and phenotypical characteristics, A. ferrireducens was reclassified in the genus Rhodoferax in 2014. R. saidenbachensis, a second non-phototrophic species of the genus Rhodoferax was described by Kaden et al. in 2014.
