From Hydrothermal Vents to Cold Seeps: How Bacteria Sustain Ocean Life With Nicole Dubilier

Meet the Microbiologist

Nicole Dubilier, Ph.D., Director and head of the Symbiosis Department at the Max Planck Institute for Marine Microbiology, has led numerous reserach cruises and expeditions around the world studying the symbiotic relationships of bacteria and marine invertebrates. She discusses how the use of various methods, including deep-sea in situ tools, molecular, 'omic' and imaging analyses, have illuminated remarkable geographic, species and habitat diversity amongst symbionts and emphasizes the importance of discovery-driven research over hypothesis-driven methods.

Ashley's Biggest Takeaways:

• In 1878, German surgeon, botanist and microbiologist, Heinrich Anton de Bary, first described symbiosis as the living together of two or more different organisms in close physical intimacy for a longer period of time.
• These relationships can be beneficial, detrimental or commensal, depending on the organisms involved.
• Microbial symbiosis research holds great potential to contribute to sustainable energy production and environmental health.
