Abstract
This paper proposes a new model of bacteria including not only intracellular information processing but also motor control on the basis of the molecular evidence. E. coli is chosen as a target bacterium, which has a simple molecular structure and is amenable to biochemical and genetic analysis. We focus on the bacterial intelligent behavior called chemotaxis in order to develop its computer model. Parameters included in the model are determined using an optimization technique in order to maximize a fitness representing a chemotactic ability. Results of the computer simulations are compared with the behavior of E. coli to show the effectiveness and validity of the proposed model.
