Abstract. A microscopic model for a bacterial individual is proposed, and applied investigation of the bacterial colony. B. Subtilis is considered as a sample, which is regarded as a rod molecule moving and rotating on the substrate including the diffusive nutrients. The model is analyzed by Monte Carlo simulations, and several patterns observed in experiments have been generally reproduced.
