Dispersion of sulfur enables sulfur oxidation before iron oxidation in Acidithiobacillus ferrooxidans: A valuable formulation for the genetic engineering toolbox
Abstract:Acidithiobacillus ferrooxidans are acidophilic chemolithoautotrophs that
are commonly reported to exhibit diauxic population growth behavior
where ferrous iron is oxidized before elemental sulfur when both are
available, despite the higher energy content of sulfur. We have
discovered sulfur dispersion formulations that enables sulfur oxidation
before ferrous iron oxidation. The oxidation of dispersed sulfur can
lower the culture pH within days below the range where aerobic ferrous
iron oxidation can occur so t… Show more
