Swimming Velocity Modulates Enhanced Diffusion in Bacterial Suspensions

Key Points

• The research examines how swimming velocity of bacteria affects the transport properties of passive particles.
• Investigated the effects of swimming bacteria on particle diffusion in suspensions.
• Measured diffusion enhancement relative to bacterial activity.
• Analyzed the relationship between swimming velocity and diffusion properties.
• Swimming velocity significantly modulates the transport properties of passive particles.
• Diffusion enhancement correlated with changes in bacterial flux.
