Industrial microbe engineering advances with systems biology and synthetic biology, moving towards a design-based approach rather than iterative methods for better cell biology understanding and goal achievement.
Area of Science:
- Microbial Engineering
- Systems Biology
- Synthetic Biology
Background:
- Engineering industrial microbes is limited by incomplete cell biology knowledge.
- An iterative cycle of modeling, implementation, and analysis has been the standard approach.
- Recent advances in Systems Biology and Synthetic Biology offer new possibilities.
Purpose of the Study:
- To describe the transition of microbial engineering from an iterative to a design-oriented paradigm.
- To highlight key technologies enabling this shift.
- To discuss the implications for future microbial engineering.
Main Methods:
- Review of recent advances in Systems Biology technologies.
- Integration of Synthetic Biology tools for modeling and molecular implementation.
- Discussion of genome-scale metabolic models, gene expression control tools, and integrated -omics analysis.
Main Results:
- Systems Biology technologies significantly increase data collection per iteration.
- Synthetic Biology tools merge modeling with molecular implementation.
- Key technologies identified to facilitate a design-based approach.
Conclusions:
- Advances in Systems Biology and Synthetic Biology are transforming microbial engineering.
- The field is shifting towards a design-based paradigm, akin to engineering disciplines like electrical circuits.
- This paradigm shift promises more efficient and predictable microbial engineering outcomes.
