Abstract

The emergence of a so-called “superbug” which is a harmful bacterium that is resistant to existing antibiotics has led to an increasing demand for novel antibiotics. Previous studies have shown that an understanding of microbial diversity can explain bacterial coexistence and diversity which provides insight for drug discovery. To investigate the effect of interbacterial interactions on microbial diversity, a cellular automaton simulation model was first developed, then used. Different grid sizes, change of rule, spatial configuration, and different types of interaction matrices were considered and used to look at how the community structure expressed in relative presence (frequency) changes. The simulations have shown that regardless of different grid size, change of rule, and use of different types of interaction matrices, the community composition in the dynamic equilibrium obtained is constant.
