Microbes in porous environments: from active interactions to emergent feedback

Area of Science:

• Microbiology
• Biophysics
• Ecology

Background:

• Microbes inhabit a wide range of porous environments, including soil, riverbeds, human lungs, and tumors.
• Environmental factors create spatial and temporal variations, leading to stressful conditions for microbial communities.
• Understanding microbial adaptation to these biophysical constraints is crucial for various scientific fields.

Purpose of the Study:

• To review recent advances in bacterial self-organization and dispersal within porous media.
• To highlight the role of active interactions and feedback mechanisms in microbial survival and fitness.
• To identify open questions and opportunities for integrative approaches in studying microbial biophysical strategies.

Main Methods:

• Literature review focusing on recent research in microbial self-organization and dispersal.
• Analysis of studies examining bacteria in both inorganic and organic porous environments.
• Synthesis of findings on active interactions and feedback loops influencing microbial adaptation.

Main Results:

• Bacteria exhibit complex self-organization and dispersal behaviors in response to porous environments.
• Active microbial interactions and feedback mechanisms are critical for survival and fitness.
• Biophysical strategies are employed by microbes across multiple scales to colonize and thrive.

Conclusions:

• Further research using integrative approaches is needed to fully understand microbial biophysical strategies.
• Advances in studying microbial adaptation can inform applications in environmental science, medicine, and biotechnology.
• Elucidating these strategies is key to making diverse porous settings habitable for microbes.
