Oxygen-dependent growth of the obligate anaerobe Desulfovibrio vulgaris Hildenborough.

By M S Johnson, I B Zhulin, M E Gapuzan and B L Taylor

Abstract

Desulfovibrio vulgaris Hildenborough, a sulfate-reducing bacterium classified as an obligate anaerobe, swam to a preferred oxygen concentration of 0.02 to 0.04% (0.24 to 0.48 microM), a level which also supported growth. Oxygen concentrations of 0.08% and higher arrested growth. We propose that in zones of transition from an oxic to an anoxic environment, D. vulgaris protects anoxic microenvironments from intrusion of oxygen
