Synthetic Biology Experiment: Engineering E. coli for Hydrogen Production
Experiment Overview
This experiment demonstrates the principles of synthetic biology by engineering E. coli bacteria to produce hydrogen. Hydrogen is a clean and renewable energy source, and synthetic biology offers a promising approach for developing efficient biological hydrogen production systems.
Materials
- E. coli strain BL21(DE3)
- Plasmid containing the hydrogenase gene cluster
- Isopropyl β-D-thiogalactopyranoside (IPTG)
- Nutrient broth
- Hydrogen electrode
- Gas chromatograph
Procedure
1. Transformation of E. coli
Transform E. coli with the plasmid containing the hydrogenase gene cluster.
2. Culture Growth
Grow the transformed E. coli in nutrient broth at 37°C.
3. IPTG Induction
Once the culture has reached an optical density of 0.6, induce hydrogen production by adding IPTG.
4. Hydrogen Measurement
Connect the hydrogen electrode to the gas chromatograph. Bubble the produced gas through the hydrogen electrode to measure the hydrogen concentration.
5. Data Analysis
Plot the hydrogen production rate over time. Calculate the specific hydrogen production rate.
Key Procedures
