Abstract: The use of pyrite as an electron donor for biological denitrification has the potential to reduce alkalinity consumption and sulfate by-product production compared with sulfur oxidizing denitrification. This research investigated the effects of oyster shell… read more here.

Abstract: Certain anaerobic microorganisms evolved a mechanism to use H2 as a reductant in their energy metabolisms. For these purposes, the microorganisms developed H2-activating enzymes, which are aspirational catalysts in a sustainable hydrogen economy. In the… read more here.

DOI: 10.3390/ijerph191811763
Abstract: The presence of organic co-substrate in groundwater and soils is inevitable, and much remains to be learned about the roles of organic co-substrates during pyrite-based denitrification. Herein, an organic co-substrate (acetate) was added to a… read more here.
