An obligately aerobic soil bacterium activates fermentative hydrogen production to survive reductive stress during hypoxia.

Abstract

Oxygen availability is a major factor and evolutionary force determining the metabolic strategy of bacteria colonizing an environmental niche. In the soil, conditions can switch rapidly between oxia and anoxia, forcing soil bacteria to remodel their energy metabolism accordingly. Mycobacterium is a dominant genus in the soil, and all its species are… (More)
