The research appears in the Nov. 18, 2005 issue of the Journal of Biological Chemistry, in the article "A New Type of Sulfite Reductase, a Novel Coenzyme F420-dependent Enzyme, from the ...

An optimal solution would be to find a methanogen that reduces sulfate, which is cheap, abundant, and a completely safe sulfur source," says Wagner. In fact, this methanogen already exists, it is ...

Role of transition metal ions in the formation of sulfate aerosols underestimated. Harris’ measurements showed that sulfate in clouds forms mostly through the oxidation of sulfur dioxide (SO 2) by ...
