Description

There are several mathematical models describing bacterial population growth, dependent of one or of several resources. These models apply to communities of single species and in general they describe well the short-term evolution of these communities. However, nature is more complex and species depend on different nutrients for growth. In this context, more complex growth phenomena emerge. In most of these models, it is assumed that each resource is sufficient to ensure the proliferation of species.

We want to analyze and develop models where several nutrients are necessary for growth and to analyze the eventual long-term limitations on the number of species competing for the same pool of resources. We intend to develop a model and to calibrate it with observed data. Then these models could be generalized to include the case where growth is only achieved with different complimentary resources. We also pretend to analyze the case of many resources and species and to study the possibility of emergence of competitive exclusion and/or coexistence.
