TLDR
A growing body of theoretical and experimental population studies indicates that the interactions within and between bacterial species can have a profound impact on the outcome of competition in nature.Abstract:
Most natural environments harbour a stunningly diverse collection of microbial species. In these communities, bacteria compete with their neighbours for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microorganisms. In addition, a growing body of theoretical and experimental population studies indicates that the interactions within and between bacterial species can have a profound impact on the outcome of competition in nature. The next challenge is to integrate the findings of these laboratory and theoretical studies and to evaluate the predictions that they generate in more natural settings.read more

Optimality and robustness in quorum sensing (QS)-mediated regulation of a costly public good enzyme
TL;DR: It is shown that exoen enzyme production is overall advantageous only if initiated at a sufficiently high density, which sets the potential advantage for QS-mediated regulation when the initial density is low and the growth cycle is sufficiently long compared with the exoenzyme response time.

Trophic Interactions and the Drivers of Microbial Community Assembly
TL;DR: It is argued that networks of trophic interactions, in which the metabolic excretions of one species are the primary resource for another, constitute the central drivers of microbial community assembly.

The evolution of siderophore production as a competitive trait.
TL;DR: Although siderophores can act as a cooperative good for single genotypes, it is argued that their role in competition is fundamental to understanding their biology, which suggests that some sidersophores are upregulated in response to competition akin to competitive traits like antibiotics.

TL;DR: Genome analysis revealed a wide array of traits that may allow these strains to be successful rhizosphere colonizers, including surface polysaccharides, uptake transporters and catabolic enzymes for nutrients, diverse iron-acquisition systems, cell wall-degrading enzymes, type I and IV pili, and novel T1SS and T5SS secreted adhesins.
Journal ArticleDOI
Migration and horizontal gene transfer divide microbial genomes into multiple niches.
TL;DR: An eco-evolutionary model is developed and shows how genetic transfer, even when rare, can transform the evolution and ecology of microbes and explains how ecologically important loci can sweep through competing strains and species.

The Growth of Bacterial Cultures
TL;DR: Bacterial growth is considered as a method for the study of bacterial physiology and biochemistry, with the interpretation of quantitative data referring to bacterial growth limited to populations considered genetically homogeneous.
