Rationally designed microbial communities in agri-food production systems: from research to market

Area of Science:

• Microbiology
• Agricultural Science
• Synthetic Biology

Background:

• Primary production requires sustainable systems to minimize environmental impact and climate change.
• Rationally designed microbial communities (microbial consortia) offer a path towards sustainable agri-food production.
• These communities can enhance ecosystem resilience, bioremediation, industrial processes, and disease prevention.

Purpose of the Study:

• To discuss the methodology for rationally designing microbial communities for agri-food production systems.
• To outline a technical approach for developing microbial consortia for market applications.
• To emphasize the importance of host-microbe interactions in microbial community design.

Main Methods:

• Utilizing in silico (genomic) and in vitro approaches for microbial consortia development.
• Integrating host-microbe interactions from the early stages of design.
• Considering the host of interest, a library of microbial species (slow and fast-growing), and genomic functional information.

Main Results:

• Current approaches often separate in silico and in vitro methods, neglecting crucial host-microbe interactions.
• A holistic approach is needed, incorporating host factors and comprehensive microbial genomic data.
• The proposed methodology ensures a more robust and effective design of microbial consortia.

Conclusions:

• Successful market application of rationally designed microbial communities requires a technical framework that includes the host, diverse microbial species, and functional genomic data.
• Integrating host-microbe interactions early is critical for effective microbial community assembly and desired host phenotypes.
• This approach paves the way for sustainable agri-food production through engineered microbial solutions.
