Abstract: Models of dilute systems of bacteria swimming in a nematic liquid crystal are developed and analyzed. The motion and orientation of the bacteria are simulated using ordinary differential equations coupled with the partial differential equations modeling the nematic liquid crystal (Ericksen Leslie equations). The analysis and numerical simulations of this system are shown to predict interesting phenomena observed experimentally.
