Isobutanol
Short summary
The aim of the third module of our project is the production of isobutanol in E. coli. The bacteria should use the products of the carbon dioxide fixation from module II to produce the key metabolite pyruvate. This pyruvate is then used for further metabolism. Pyruvate is considered as a key metabolite because it can be used as a precursor for different industrial relevant products.
We decided to introduce an isobutanol production pathway which starts with pyruvate and is called 2-keto-acid, or Ehrlich, pathway (Pamela P. Peralta-Yahya et al., 2012). For this we want to use and improve existing BioBricks from iGEM Team Formosa 2011/2012.
Different producing pathways of variable high value products derive from pyruvate. For further purpose the modularity of BioBricks can be used to enable the exchange of those producing systems. Other thinkable products than isobutanol would be isoprene, putrescine or even antibiotics.
Here you will find our results of the isobutanol production.
