all these agents are bactericidal; i.e. lethal to most marine bacteria even in small quantities; while aerobe bacterial species are capable of growth at full oxygen tension (pO2 of air 21%) and others tolerate even hyperbaric concentrations, most marine species are micro-aerophiles or strict anaerobes. Prokaryotic members of the genus Vibrio for example are typically facultatively aerobes and possess a fermentative metabolism. Aurantimonas …. See Busse paper; Beggiatoa requires oxygen to metabolise sulfur components, whereas Desulfovibrio requires anoxic conditions to reduce sulfur; similar to members of Oscillatoria likewise prefer anoxic conditions but are autotrophs;

some microbial pathogens have developed mechanisms to neutralize the effects of oxygen-dependent phagocytic killing;
