Research Abstract

Changes in atmospheric concentrations of greenhouse gases (GHGs) and aerosols are drivers of climate change. N_2O and CH_4 are important GHGs and H_2S is related to aerosol formation. To develop the source-sink analyses of these gases using their isotopomer signals, we quantified relationships between some microbial processes and their isotopomer signals in pure culture and co-culture conditions.
