Ethanoligenens harbinense is a strictly anaerobic bacterium. 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).[2] This hydrogen producing, fermenting bacteria shows potential for bio-related application.[3]
Metabolism
[edit]Ethanoligenens harbinense metabolizes glucose and carbon sources to produce hydrogen, acetic acid, carbon dioxide, and ethanol.[4]This metabolism is catalyzed by pyruvate ferradoxin 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]
Application
[edit]Ethanoligenens harbinense has the ability to produce bio-hydrogen through its metabolism, which can be used for sustainable energy technology.[5] This is shown to be feasible for affordable bio-hydrogen production by the use of bioreactors.[6] 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.[7]
