TLDR
The extent of mutually positive interaction among bacterial strains isolated from a common aquatic environment is studied and it is shown that in pairwise species combinations, the great majority of interactions are net negative and there is no evidence that strong higher-order positive effects arise when more than two species are mixed together.About:

Biofilms: an emergent form of bacterial life.
Hans-Curt Flemming,Jost Wingender,Ulrich Szewzyk,Peter D. Steinberg,Scott A. Rice,Staffan Kjelleberg +5 more
TL;DR: The fundamental role of the biofilm matrix is considered, describing how the characteristic features of biofilms — such as social cooperation, resource capture and enhanced survival of exposure to antimicrobials — all rely on the structural and functional properties of the matrix.

The ecology of the microbiome: Networks, competition, and stability
TL;DR: This finding indicates that hosts can benefit from microbial competition when this competition dampens cooperative networks and increases stability, and indicates that stability is promoted by limiting positive feedbacks and weakening ecological interactions.

Feed Your Friends: Do Plant Exudates Shape the Root Microbiome?
TL;DR: In this paper, physiological factors of plants that may govern plant-microbe interactions, focusing on root physiology and the role of root exudates, are discussed, and a possible sequence of events governing rhizobiome assembly is elaborated.

Deciphering microbial interactions and detecting keystone species with co-occurrence networks.
David Berry,Stefanie Widder +1 more
TL;DR: In this article, the authors simulate multi-species microbial communities with known interaction patterns using generalized Lotka-Volterra dynamics, construct co-occurrence networks, and evaluate how well networks reveal the underlying interactions, and how experimental and ecological parameters can affect network inference and interpretation.
Journal ArticleDOI
Spatial structure, cooperation and competition in biofilms
TL;DR: How the spatial arrangement of genotypes within a community influences the cooperative and competitive cell–cell interactions that define biofilm form and function is discussed.

QUORUM SENSING: Cell-to-Cell Communication in Bacteria
TL;DR: This review focuses on the architectures of bacterial chemical communication networks; how chemical information is integrated, processed, and transduced to control gene expression; how intra- and interspecies cell-cell communication is accomplished; and the intriguing possibility of prokaryote-eukaryote cross-communication.
Journal ArticleDOI
Biofilms as complex differentiated communities.
TL;DR: It is submitted that complex cell-cell interactions within prokaryotic communities are an ancient characteristic, the development of which was facilitated by the localization of cells at surfaces, which may have provided the protective niche in which attached cells could create a localized homeostatic environment.
Journal ArticleDOI
Bacterial competition: surviving and thriving in the microbial jungle
TL;DR: 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.

TL;DR: It is indicated that upon attack by a fungal root pathogen, plants can exploit microbial consortia from soil for protection against infections.

Social semantics: altruism, cooperation, mutualism, strong reciprocity and group selection.
TL;DR: The aim here is to address issues of semantic confusion that have arisen with research on the problem of cooperation, and to emphasize the need to distinguish between proximate (mechanism) and ultimate (survival value) explanations of behaviours.
