[Cellular automata approach to biological pattern formation. (II): The growth pattern of bacterial colonies].

The investigation of the mechanism of biological pattern has been an important topic of life sciences, especially of developmental biology, for a long time. We have established a cellular automata model of biological pattern formation, which defines how to form a biological pattern from individual cells and their behaviors, cell-cell interactions, and cell-environment interactions. In this paper, we use that model to simulate the growth pattern of the bacterial colonies in consideration of the effects of both nutrient and metabolite on the cell's reproduction.
