Anaerobic reduction of manganese oxides and its effect on the carbon and nitrogen cycles
(Georgia Institute of Technology, 2012-04-04)The biogenic reduction of Mn(IV) oxides is one of the most favorable anaerobic electron transfer processes in aquatic systems and likely plays an important role in the redox cycle of both carbon and nitrogen in anaerobic ... -
Interactions between reactive nitrogen and manganese: Implications for marine nitrous oxide cycling
(Georgia Institute of Technology, 2020-04-25)Nitrous oxide (N2O) is a potent greenhouse gas that can destroy stratospheric ozone. Production and consumption of N2O has long been assumed to be controlled solely by nitrogen-metabolizing microbes. It has recently been ... -
Role of thiols in microbial metal reduction and Importance of organic-Fe(III) complexes on the benthic flux of iron from continental margin sediments
(Georgia Institute of Technology, 2018-08-24)Both Fe(III) and Mn(III,IV) oxides are ubiquitous in aquatic sediments and represent favorable terminal electron acceptors for microbial respiration. As a result, the dissimilatory reduction of Fe(III) and Mn(III,IV) ...
