Hydrogen evolution by strictly aerobic hydrogen bacteria under anaerobic conditions [PDF]

Journal of Bacteriology, 1984
When strains and mutants of the strictly aerobic hydrogen-oxidizing bacterium Alcaligenes eutrophus are grown heterotrophically on gluconate or fructose and are subsequently exposed to anaerobic conditions in the presence of the organic substrates, molecular hydrogen is evolved.
