“How to anaerobically oxidize hydrocarbons: Lessons from hydrothermal (and cold) marine sediments”Dr. Gray ChadwickDivision of Geological and Planetary Sciences, CalTechMonday, Sept. 21, 3:10 p.m. MDTvia WebExThe use of short chain hydrocarbons as growth substrates by anaerobic microorganisms is challenging from both an energetic and biochemical perspective. Much of what we have learned about these metabolisms comes from isolates and enrichments from hydrothermal marine sediments. In this talk Dr. Chadwick will discuss our prior understanding of these processes from pure cultures and recent developments in our understanding from enrichment cultures and metagenomic analysis of a range of habitats. The interesting dichotomy between fumarate-addition based hydrocarbon activation vs. methyl-coenzyme reductase (MCR) homolog reversal as biochemical strategies, and the apparent preference for syntrophic interactions in the latter, will be discussed.TBI Host: Dr. Roland HatzenpichlerIf you would like to meet with Dr. Chadwick, email Dr. Roland HatzenpichlerMeeting number: 120 380 7939Password: GrayTBI2020
