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

Biodiversity of culturable psychrotrophic microbiota in raw milk attributable to refrigeration conditions, seasonality and their spoilage potential
Nuwan R. Vithanage,Muditha Dissanayake,Greg Bolge,Enzo A. Palombo,Thomas Yeager,Nivedita Datta +5 more
TL;DR: Refrigerated storage of raw milk promotes the growth of psychrotrophic bacteria, some of which produce heat-stable exoenzymes causing dairy product spoilage.

Inflammation Fuels Colicin Ib-Dependent Competition of Salmonella Serovar Typhimurium and E. coli in Enterobacterial Blooms
Lubov Petkova Nedialkova,Rémy Denzler,Martin B. Koeppel,Manuel Diehl,Diana Ring,Thorsten Wille,Roman G. Gerlach,Bärbel Stecher +7 more
TL;DR: A so-far unappreciated role of inflammation-inflicted blooms as an environment favouring ColIb-dependent competition of pathogenic and commensal representatives of the Enterobacteriaceae family is uncovers.

Conditional toxicity and synergy drive diversity among antibacterial effectors.
Kaitlyn D. LaCourse,S. Brook Peterson,Hemantha D. Kulasekara,Matthew C. Radey,Jungyun Kim,Joseph D. Mougous +5 more
TL;DR: It is shown that the multiple effectors delivered to competitor bacteria by the type VI secretion system of Pseudomonas aeruginosa display conditional efficacy and act synergistically, which elucidates why some bacteria carry multiple toxins with distinct activities.

Cellular cooperation: insights from microbes
Hasan Celiker,Jeff Gore +1 more
TL;DR: Recent advances made in understanding how cooperation and multicellularity can evolve in microbial populations in the face of such conflicts are summarized and parallels with cell populations within multICEllular organisms are discussed.

TL;DR: This work sampled soils and saprolite from three sites in a northern California Critical Zone Observatory with various vegetation and bedrock characteristics and reconstructed 1,334 metagenome-assembled genomes containing diverse biosynthetic gene clusters (BGCs) for secondary metabolite production.

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.
