Many bacterial species produce toxins that inhibit their competitors. We model this phenomenon by extending classic two-species Lotka-Volterra competition in one spatial dimension to incorporate toxin production by one species. Considering solutions comprising two adjacent single-species colonies, we show how the toxin inhibits the susceptible species near the interface between the two colonies. Moreover, a sufficiently effective toxin inhibits the susceptible species to such a degree that an… Expand


Competitive interactions in Escherichia coli populations: the role of bacteriocins
In vitro, in vivo and in silico models used to study competitive interactions between bacteriocin producers suggested that localized interactions between producers of DNA-degrading toxins can lead to stable coexistence of heterogeneously distributed strains within the bacterial community and to the maintenance of diversity.

It is suggested that structured habitats are more favorable for the evolution of colicinogenic bacteria than liquid cultures, which exist as randomly distributed individuals and as single-clone colonies. Expand
Coexistence of two competitors on one resource and one inhibitor: a chemostat model based on bacteria and antibiotics.
A continuous time model of the dynamics of two species competing for a single limiting resource in the presence of a substance that inhibits the growth of one of the species suggests that coexistence of sensitive and resistant species is structurally unstable. Expand
The Ecology and Evolution of Microbial Competition.
Open questions and theoretical predictions of the long-term dynamics of competition that remain to be tested are highlighted to better predict the behaviour of microbes, and to control and manipulate microbial communities for industrial, environmental, and medical purposes. Expand
The effects of spatial structure, frequency dependence and resistance evolution on the dynamics of toxin-mediated microbial invasions
The findings suggest that manipulation of the nasal microbial community could be used to limit colonization by S. aureus, which might limit transmission and infection rates. Expand
Competition in the chemostat when one competitor produces a toxin
The usual models of the chemostat assume that the competition is purely exploitative, the competition is only through the consumption of the nutrient. However, it is known that microorganisms canExpand
Spreading speed and linear determinacy for two-species competition models
This paper derives a set of sufficient conditions for linear determinacy in spatially explicit two-species competition models, which can be interpreted as requiring sufficiently large dispersal of the invader relative to dispersals of the out-competed resident and sufficiently weak interactions between the resident and the Invader.

Interference competition and invasion: spatial structure, novel weapons and resistance zones.
Interference can significantly increase an invader's competitiveness, and its growth when rare, if interactions are structured spatially, and enhances the common, resident species' resistance to invasion independently of spatial structure, unless the propagation-cost is too great. Expand
A model of allelopathy in the context of bacteriocin production
A model of this situation in the chemostat is formed by incorporating parameters that measure relatedness and mutation rates as well as the cost of toxin production into standard competition models and shows that depending upon growth rates and toxin sensitivity, coexistence of competitors may or may not occur.

Continuous model for the rock–scissors–paper game between bacteriocin producing bacteria
For the first time, a continuous, spatially homogeneous model that describes the competitive interaction between bacteriocin-producing, resistant and sensitive bacteria is established and the dynamics generated by that model is analyzed. Expand
