Mathematical Modeling of Microbial Community Dynamics: A Methodological Review
Microorganisms in nature form diverse communities that dynamically change in structure and function in response to environmental variations. As a complex adaptive system, microbial communities show higher-order properties that are not present in individual microbes, but arise from their interactions. Predictive mathematical models not only help to understand the underlying principles of the dyn...

متن کاملNutrient cross-feeding in the microbial world
The stability and function of a microbial community depends on nutritional interactions among community members such as the cross-feeding of essential small molecules synthesized by a subset of the population. In this review, we describe examples of microbe-microbe and microbe-host cofactor cross-feeding, a type of interaction that influences the forms of metabolism carried out within a communi...
متن کاملMicrobial community dynamics in MFCs
38 The performance and dynamics of the bacterial communities in the biofilm and suspended 39 culture in the anode chamber of sucrose-fed microbial fuel cells (MFCs) were studied by using 40 Denaturing Gradient Gel Electrophoresis (DGGE) of PCR-amplified partial 16S rRNA genes 41 followed by species identification by sequencing. The power density of MFCs was correlated to 42 the relative proport...
متن کاملEstimating the probability of coexistence in cross-feeding communities.
The dynamics of many microbial ecosystems are driven by cross-feeding interactions, in which metabolites excreted by some species are metabolised further by others. The population dynamics of such ecosystems are governed by frequency-dependent selection, which allows for stable coexistence of two or more species. We have analysed a model of cross-feeding based on the replicator equation, with t...
