Biofilms are multicellular communities formed by densely-packed microbes that are often associated with persistent infections. Steep gradients of nutrients and oxygen form in these crowded structures. The human pathogen Pseudomonas aeruginosa produces molecules called phenazines that help it to cope with the oxygen-limited conditions within biofilms. Columbia researchers have uncovered new roles for proteins of the electron transport chain that implicate them in utilization of phenazines. Illustration by Nicoletta Barolini.

Columbia University biologists have revealed a mechanism by which bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the cell.
