Area of Science:

  • Microbiology
  • Synthetic Biology
  • Ecology

Background:

  • Interbacterial antagonism significantly impacts microbiome assembly and stability.
  • These interactions can be harnessed to modulate microbial communities in diverse environments.

Purpose of the Study:

  • To highlight key mechanisms of interspecies antagonism.
  • To discuss advances in using antagonism for microbiome engineering.
  • To outline ecological design principles for synthetic microbial communities.

Main Methods:

  • Review of mechanisms of interspecies antagonism (direct contact, secreted molecules).
  • Discussion of recent advances in microbiome engineering using antagonism.
  • Application of ecological design principles for synthetic community assembly.

Main Results:

  • Identified direct cell-to-cell contact and secreted biomolecules as key antagonism mechanisms.
  • Highlighted advances in engineering altered functions and specificities for microbiome applications.
  • Outlined bottom-up assembly of synthetic microbial communities using antagonistic interactions.

Conclusions:

  • Manipulating microbial communities via negative interactions is critical for understanding microbiome processes.
  • Exploiting interbacterial antagonism is essential for developing new microbiome engineering applications.
