Multimodal Microorganism Development: Integrating Top-Down Biological Engineering with Bottom-Up Rational Design

Area of Science:

• Biological Engineering
• Synthetic Biology
• Systems Biology

Background:

• Biological engineering aims to address significant societal challenges.
• Current engineering approaches must integrate technical, economic, and social considerations.
• Developing robust and functional biological systems requires efficient and cost-effective methods.

Purpose of the Study:

• To compare foundational engineering approaches: bottom-up (gene/pathway-level) and top-down (whole-genome).
• To identify the complementarity and synergy between these distinct engineering strategies.
• To demonstrate how multimodal engineering advances strain development in synthetic biology.

Main Methods:

• Comparative analysis of bottom-up and top-down engineering paradigms.
• Case studies involving the engineering of Saccharomyces cerevisiae.
• Integration of gene-targeted and whole-genome engineering for multimodal approaches.

Main Results:

• Significant complementarity exists between bottom-up and top-down engineering.
• A combined approach, exemplified in Saccharomyces cerevisiae, demonstrates synergistic benefits.
• Multimodal engineering effectively streamlines strain development by bridging design knowledge gaps.

Conclusions:

• The dual-track approach of combining whole-genome and gene-targeted engineering is crucial for complex biological systems.
• This integrated strategy enhances the realization of synthetic biology's potential.
• Multimodal engineering overcomes limitations in rational design for biological systems.
