Many production processes using microorganisms face the dilemma of conflicting production products and key metabolic pathways. This means that simply introducing product-synthesising genes into an engineered bacterium can greatly affect the growth of the microorganism, leading to a situation where production is too low.

Usage and Biology

Many production processes using microorganisms face the dilemma of conflicting production products and key metabolic pathways. This means that simply introducing product-synthesising genes into engineered bacteria can greatly affect the growth of the microorganism, leading to a situation where production is too low. There are a number of current solutions to this problem. For example, using metabolic engineering to regulate metabolic flow using gene knockdown, promoter replacement, etc. These static strategies are effective for productivity improvement, but are not responsive to changes in the cell or environment.

This part is about PHB Production Regulation based on an three-layer dynamic regulation model. It successfully regulate the PHB production by dividing the process into 3 phases: Growth Phase, Production Phase and Product-release Phase. In this way, the cell factory can firstly grow

1. Three-layer Dynamic Regulation Model

2. The first layer--Growth control

3. The second layer--Production control

4. The Third layer--Product-release control

Characterization

1. Protocols

2. The Characterization of PesaS and PesaRwt/PesaRc/PesaRp

3. The Characterization of PesaRwt/PesaRc/PesaRp and PYU3/PYU7/PYU16/PYU92

Summary of Results

Our part provides an example for future iGEM team
