Conclusion

The main aim of our “E.coline” project is to generate isobutanol, a promising eco-fuel, in a productive and efficient way.To produce isobutanol, at first we use four pyruvate catalytic enzyme genes: alsS, ilvC, ilvD, kivD all. We then designed a temperature control system to allow E.coli to produce optimum isobutanol before being poisoned by isobutyaldehyde. According to our data(Figure 8), our temperature control system had been proven to work successfully.To produce isobutanol more efficiently, we combined zinc fingers and our enzymes together and put the fusion proteins in catalytic pathway order, thus the isobutanol conversion process can be accelerated.
