ABSTRACT

Biogeochemical reactions and their rates are largely controlled by microbes. There is thus a growing interest in the inclusion of complex microbial communities, their functioning, and interactions into reactive transport models. Conventionally, these models have included thermodynamic-based approaches that describe the stoichiometry and energetics of microbial reactions. In this chapter, we describe two emergent approaches that can be used to model microbial community dynamics—trait-based approach and dynamic energy allocation model. We explain their practice, limitations, and strategies for improvement.
