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

The spatial and metabolic basis of colony size variation.
TL;DR: This work tested how proximity influences colony size when either Escherichia coli or Salmonella enterica are grown on various carbon sources and found the importance of location was smaller than expected for experiments with S. enterica growing on glucose.
Journal ArticleDOI
Refining the stress gradient hypothesis in a microbial community.
TL;DR: It is demonstrated that environmental stress in the form of toxic biocides causes interactions between 4 microbial species to become positive, and the stress gradient hypothesis (SGH) provides a framework to predict when positive or negative interactions should be observed.

Multifactorial Competition and Resistance in a Two-Species Bacterial System.
Anupama Khare,Saeed Tavazoie +1 more
TL;DR: This study reveals the molecular complexity of a simple two-species interaction, an important first-step in the application of systems biology to detailed molecular dissection of interactions within native microbiomes.
Journal ArticleDOI
Soil carbon controlled by plant, microorganism and mineralogy interactions.
TL;DR: In this article, the authors focus on the competition for available carbon in soil, limiting their analyses to the interaction at rhizospheric space, where most processes between microorganisms and mineral phase occurs.

TL;DR: A new layer of interaction is revealed, whereby AM symbiosis promotes rhizobia accumulation in the rhizosphere of M. truncatula, and quantitative microbial co-abundance network analyses revealed that the AM symbiotic impacts Rhizobiales-hubs among the plant microbiota and benefit the plant holobiont.

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.
