Aerotaxis is the movement of an organism in response to environmental oxygen concentrations, either towards or away from a given oxygen concentration. Many bacteria are microaerophilic meaning they prefer environments with low oxygen content. Higher or lower O2 content than the optimum are considered a repellant and bacteria will navigate towards the optimum. This animation is an overview of studying aerotaxis in motile bacteria.
