Matters Microbial #39: Global flatulence: Mysterious Archaea and methane

May 9, 2024

Today, Dr. Geo Santiago-Martinez, Assistant Professor of Molecular and Cell Biology and Microbiology at the University of Connecticut joins the #QualityQuorum to discuss the mysteries of the archaeal world, and how one group of these organisms produce methane gas as a byproduct of metabolism.  These methanogens are thus involved in climate, symbioses, biotechnology, and even astrobiology!
