Matters Microbial #105: Snails Farming Bacteria in the Deep Sea

Let’s take a deep dive into chemoautotrophy!  Today, Dr. Roxanne Beinart, Associate Professor of Oceanography at the University of Rhode Island, joins the #QualityQuorum to discuss how some marine creatures use bacterial symbioses to provide organic compounds for growth and reproduction.
