Metalireducens

Metalireducens is a genus of bacteria belonging to the family Comamonadaceae. These microorganisms are notable for their ability to reduce metal ions, particularly iron, under anaerobic conditions. This metabolic capability plays a significant role in biogeochemical cycling within various environments, including sediments and subsurface soils. Species within this genus have been isolated from diverse locations, suggesting a widespread distribution.

The primary characteristic of Metalireducens is its dissimilatory metal reduction. This means that the reduction of metal ions serves as a terminal electron acceptor during respiration, allowing the bacteria to generate energy in the absence of oxygen. This process can influence the mobility and bioavailability of metals in the environment, potentially affecting the fate of contaminants. Research into Metalireducens contributes to our understanding of microbial metal transformations and their ecological implications. Further study is ongoing to fully elucidate the metabolic pathways and environmental significance of this bacterial genus.
