The Microbial Physiology Group was established on June 1 2016. Our group is dedicated to discovering new biochemical reactions, and to fundamentally understand microbial physiology and interactions of microorganisms in key elemental cycles. We enrich microorganisms in bioreactors under controlled conditions that closely mimic the environment, and analyze the resulting cultures using state-of-the-art omics, physiological and biochemical approaches. Our main focus is on discovering new pathways and investigating the metabolic flexibility of nitrogen and carbon cycle microorganisms. Reaching a detailed understanding of physiology and interactions of microorganisms that mediate key elemental cycles is vital to determine how biogeochemical cycles function on earth.
