Archaea adjust the number of cyclopentane rings in their glycerol dibiphytanyl glycerol tetraether (GDGT) membrane lipids as a homeostatic response to environmental stressors such as temperature, pH, and energy availability shifts. However, archaeal

Dissimilatory sulfate reduction is a microbial energy metabolism that can produce sulfur isotopic fractionations over a large range in magnitude. Calibrating sulfur isotopic fractionation in laboratory experiments allows for better interpretations of

The sulfur isotope record provides key insight into the history of Earth's redox conditions. A detailed understanding of the metabolisms driving this cycle, and specifically microbial sulfate reduction (MSR), is crucial for accurate paleoenvironmenta

Dissimilatory sulfate reduction serves as a key metabolic carbon remineralization process in anoxic marine environments. Sulfate reducing microorganisms can impart a wide range in mass-dependent sulfur isotopic fractionation. As such, the presence an

DsrC is a key protein in dissimilatory sulfur metabolism, where it works as co-substrate of the dissimilatory sulfite reductase DsrAB. DsrC has two conserved cysteines in a C-terminal arm that are converted to a trisulfide upon reduction of sulfite.

Many Archaea produce membrane-spanning glycerol dibiphytanyl glycerol tetraether (GDGTs) lipids that serve as unique biomarkers of past environments. These lipids can contain up to eight cyclopentane rings, where an increase in ring cyclization is ge

Methane generated by microorganisms is most often depleted in the doubly substituted isotopologue 12 CH2D2 relative to the stochastic reference distribution. To constrain the controls on depleted Δ 12 CH 2 D 2 values, we experimentally isolated the
