Assessing environmental gradients in relation to dark CO <sub>2</sub> fixation in estuarine wetland microbiomes

The increasing concentration of atmospheric CO<sub>2</sub> has been identified as the primary driver of climate change and poses a major threat to human society. This work explores the mostly overlooked potential of light-independent CO<sub>2</sub> fixation by soil microbes (a.k.a. dark CO<sub>2</sub> fixation) in climate change mitigation efforts. Applying a combination of molecular microbial tools, our research provides new insights into the ecological niches where CO<sub>2</sub>-fixing pathways are most active. By identifying how environmental factors, like oxygen, salinity and organic matter availability, influence these pathways in an estuarine wetland environment, potential strategies for enhancing natural carbon sinks can be developed. The importance of our research is in advancing the understanding of microbial CO<sub>2</sub> fixation and its potential role in the global climate system.

Abstract

The increasing concentration of atmospheric CO<sub>2</sub> has been identified as the primary driver of climate change and poses a major threat to human society. This work explores the mostly overlooked potential of light-independent CO<sub>2</sub> fixation by soil microbes (a.k.a. dark CO<sub>2</sub> fixation) in climate change mitigation efforts. Applying a combination of molecular microbial tools, our research provides new insights into the ecological niches where CO<sub>2</sub>-fixing pathways are most active. By identifying how environmental factors, like oxygen, salinity and organic matter availability, influence these pathways in an estuarine wetland environment, potential strategies for enhancing natural carbon sinks can be developed. The importance of our research is in advancing the understanding of microbial CO<sub>2</sub> fixation and its potential role in the global climate system.
