WebIn the soil, the natural environment of B. subtilis, the bacterium continuously encounters various changing environmental conditions including drastic differences in oxygen tension. For example, a rain shower reduces the accessibility of oxygen, as the diffusion rate of oxygen in water is approximately 10,000 times lower than in the gaseous phase. Webdioxide production helps oxygen to be released at a lower pressure. This means oxygen can be easily delivered to the muscles and tissues during times of increased oxygen demand, such as exercise [1,6,11,12]. These last few sections briefly cover some of the main concepts involved with oxygen transport and utilization within the realm of physiology.
