Evolutionary History Of Bacteria News Medical & Diet Health
How bacteria survive in oxygen-poor environments. Biologists have revealed a mechanism by which bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the cell. The finding could explain how some bacteria, such as Pseudomonas aeruginosa (P. Aeruginosa), are able to thrive in oxygen-poor environments like biofilms and resist antibiotics. P. Aeruginosa biofilm infections are a leading cause of death for people suffering from cystic fibrosis, a genetic condition that affects the lungs and the digestive system. Source 8p.
