Understanding The Molecular Mechanisms Involved In Nitrous Oxide Reduction By Deep-sea Hydrothermal Vent Bacteria

by Keith Cowing

Nitrous oxide (N2O) is the third most potent greenhouse gas after carbon dioxide and methane. It can also be oxidized by physical processes to form ozone-depleting substances. Atmospheric concentrations of […]

Non-thermodynamic Factors Affect Competition Between Thermophilic Chemolithoautotrophs From Deep-sea Hydrothermal Vents

by Keith Cowing

Various environmental factors, including H2 availability, metabolic tradeoffs, optimal growth temperature, stochasticity, and hydrology, were examined to determine if they affect microbial competition between three autotrophic thermophiles.
