Temperate phages as self-replicating weapons in bacterial competition [PDF]

Journal of the Royal Society Interface, 2017
Abstract Microbial communities are accompanied by a diverse array of viruses. Through infections of abundant microbes, these viruses have the potential to mediate competition within the community, effectively weakening competitive interactions and promoting coexistence.

Bacterial–Fungal Interactions: Mutualism, Antagonism, and Competition

Life
The interaction between bacteria and fungi is one of the key interactions of microbial ecology, including mutualism, antagonism, and competition, which profoundly affects the balance and functions of animal microbial ecosystems.

The evolution of short- and long-range weapons for bacterial competition. [PDF]

Nat Ecol Evol, 2023
AbstractBacteria possess a diverse range of mechanisms for inhibiting competitors, including bacteriocins, tailocins, type VI secretion systems and contact-dependent inhibition (CDI). Why bacteria have evolved such a wide array of weapon systems remains a mystery.

Multifaceted Interfaces of Bacterial Competition. [PDF]

J Bacteriol, 2016
ABSTRACT Microbial communities span many orders of magnitude, ranging in scale from hundreds of cells on a single particle of soil to billions of cells within the lumen of the gastrointestinal tract. Bacterial cells in all habitats are members of densely populated local environments that facilitate competition between neighboring cells ...

Essential role of membrane vesicles for biological activity of the bacteriocin micrococcin P1

Journal of Extracellular Vesicles, 2022
Bacterial membrane vesicles (MVs) have recently gained much attention and have been shown to carry a wide diversity of secreted bacterial components.

Engineering Bacterial Competitiveness and Persistence in the Phytosphere [PDF]

Molecular Plant-Microbe Interactions®, 2002
Several tactics exist to improve the survival of an introduced microorganism of interest in the plant environment. One, derived from studies on the Agrobacterium-plant interaction and the role of opines in this interaction, proposes to promote growth of the inoculant in the plant environment via the establishment of a bias in the rhizosphere.

The idiosyncrasy of spatial structure in bacterial competition. [PDF]

BMC Res Notes, 2015
The spatial structure of a habitat can have a strong impact on community dynamics. Different experimental approaches exist to explore the effect of spatial structure on bacterial communities. To investigate the effect of 'space', a single implementation of spatial structure is often contrasted to bacterial community dynamics in well-mixed cultures ...

The evolution of strategy in bacterial warfare via the regulation of bacteriocins and antibiotics

eLife, 2021
Bacteria inhibit and kill one another with a diverse array of compounds, including bacteriocins and antibiotics. These attacks are highly regulated, but we lack a clear understanding of the evolutionary logic underlying this regulation.

Competitive effects in bacterial mRNA decay

Journal of Theoretical Biology, 2020
In living organisms, the same enzyme catalyses the degradation of thousands of different mRNAs, but the possible influence of competing substrates has been largely ignored so far. We develop a simple mechanistic model of the coupled degradation of all cell mRNAs using the total quasi-steady-state approximation of the Michaelis-Menten framework ...

Competitive adherence as a mechanism of bacterial interference [PDF]

Canadian Journal of Microbiology, 1983
To determine whether competition among bacteria for specific attachment sites on host cells can explain bacterial interference, Staphylococcus aureus strain 502A was tested in turn against two different nasal coryneforms, a strain of Pseudomonas aeruginosa, and a virulent strain of S. aureus, all in the presence of nasal mucosal cells.
