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.
摘要
希登伯勒脱硫弧菌是一种硫酸盐还原菌，被归类为专性厌氧菌，它会游向0.02%至0.04%（0.24至0.48微摩尔）的适宜氧气浓度，这一浓度也能支持其生长。0.08%及更高的氧气浓度会抑制生长。我们认为，在从有氧环境向无氧环境过渡的区域，希登伯勒脱硫弧菌可保护无氧微环境免受氧气侵入。
