A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]
, 2011 In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]
, 2014 Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of
