Synthetic microbial community (SynCom) biosensors integrate synthetic ecology and computational design for enhanced detection. These engineered consortia offer improved sensing capabilities over traditional whole-cell biosensors (WCBs).
Area of Science:
- Synthetic biology
- Microbial ecology
- Biosensor development
Background:
- Whole-cell biosensors (WCBs) offer low-cost detection but face limitations like cellular burden and signal complexity.
- Natural microbial consortia distribute functions across populations, providing a model for complex sensing systems.
Purpose of the Study:
- To review the development of synthetic microbial community (SynCom) biosensors.
- To highlight the transition from WCBs to engineered multicellular biosensors.
- To discuss the role of artificial intelligence (AI) in SynCom biosensor design and operation.
Main Methods:
- Review of literature on WCBs, natural microbial consortia, and SynCom biosensors.
- Emphasis on functional partitioning, signal routing, and community control strategies.
- Exploration of AI applications in design space, interaction prediction, and signal decoding.
Main Results:
- SynCom biosensors translate natural consortium logic into engineered platforms with defined members and roles.
- AI assists in narrowing design space, predicting interactions, and decoding complex biosignals.
- Key challenges include community stability, orthogonal communication, data quality, and real-sample validation.
Conclusions:
- SynCom biosensors represent an advancement over WCBs by distributing sensing functions across engineered microbial populations.
- AI is crucial for optimizing SynCom design, operation, and data interpretation.
- Future progress requires robust community design, containment, validation, and computational integration.
