Modular bacterial systems for antibiotics-free protein production

Overview

The University of Tennessee, Knoxville, presents a groundbreaking solution for protein production without the use of antibiotics. This platform utilizes engineered modular bacterial cells that are free from condition-dependent essential genes, endogenous transposons, and toxins. The system is tightly integrated with a protein production module, ensuring that the cell's metabolic function is linked to the overproduction of targeted proteins. This design not only enhances protein yield but also eliminates the reliance on antibiotics, offering a cleaner, more sustainable approach to protein manufacturing.

Technical specifications

Key features:

• Modular cell design: Lacks condition-dependent essential genes, reducing genetic complexity.
• Antibiotics-free system: Eliminates the need for antibiotics by coupling cell metabolism with protein production.
• High protein yield: Metabolic and genetic coupling ensures efficient protein overproduction.
• Endogenous element-free: Absence of transposons and toxins minimizes risk of genetic instability.

Technology readiness level

This technology is currently at TRL 2, with initial design and construction of modular cells underway. Future research will focus on medium formulation and demonstrating strain performance for high protein production.
