Dissimilatory iron reduction by hyperthermophilic archaea occurs in many geothermal environments and generally relies on microbe-mineral interactions that transform various iron oxide minerals. In this study, the physiology of dissimilatory iron and nitrate reduction was examined in the hyperthermop...
Haloalkaliphilic microorganisms are double extremophiles functioning optimally at high salinity and pH. Their typical habitats are soda lakes, representing geologically ancient ecosystems which are still widespread on Earth and supposedly harbor relict microbial communities. We compared metabolic fe...
Desulfitobacterium hafniense DCB-2, a halo-respirer and versatile inorganic ion reducer, grows in hazardous waste contaminated environments. M-BM- Gene expression changes were determined when the strain was grown in the presence of high concentrations of Fe(+3), Se(+6), U(+6), or NO3(-) as alternati...
