Title: Chemotactic bacteria

Description: An isolated patch of nutrient (green) is injected into a forced, homogeneous and isotropic turbulent flow. Bacteria, which initially are uniformly distributed throughout the volume, are also advected with the flow, and have the ability to swim up concentration gradients. Relatively high (red) and low (blue) bacterial concentrations surround the nutrient filaments. Eventually the nutrient and bacteria are both homogenized by turbulent mixing.
