Biology:Ethanoligenens
Ethanoligenens harbinense is a hydrogen-producing, fermenting bacterium that shows potential for bioenergy-related applications, including biofuel production from waste streams.[1] It is the only species in the genus Ethanoligenens.[2]
Species description
It is Gram-positive, non-spore-forming, mesophilic and motile, its cells being regular rods (0.4–0.8×1.5–8.0 μm). Its type strain is YUAN-3T (=JCM 12961T =CGMCC 1.5033T).[3]
Ethanoligenens harbinense was named by Xing and co-authors in the original discovery paper, which reported that the bacterial strains had been isolated from molasses sludge wastewater. Ethanoligenens means 'ethanol-producing', and comes from 'ethanol' and the Latin verb 'genere', to produce; harbinense is a reference to Harbin, the city in China where the type strain was isolated.[3]
Ethanoligenens harbinense metabolizes glucose and carbon sources to produce hydrogen, acetic acid, carbon dioxide, and ethanol.[4] This metabolism is catalyzed by pyruvate ferredoxin oxidoreductase and genes encoding [Fe–Fe]-hydrogenase.[4] [Fe–Fe]-hydrogenase has a specific role in the hydrogen gas production in Ethanoligenens harbinense.[5] Since Ethanoligenens harbinense is a high hydrogen gas producing bacterium, it is often used as a model organism to study [Fe–Fe]-hydrogenase activity.[5]
Ethanoligenens harbinense has the ability to produce bio-hydrogen through its metabolism, which can be used for sustainable energy technology.[5] This has been shown to be feasible for affordable bio-hydrogen production by the use of bioreactors.[6][7][8] The mechanisms that give Ethanoligenens harbinense the ability to produce bio-hydrogen by fermenting organic wastes, including wastewater, allows this bacteria to be crucial for biofuel and bioenergy production.[1]
