Bioelectrogenesis

Traditional bioelectrogensis … but our circuit is well designed and of good quality. Although setbacks in assembly prevented us from actually testing the complete circuit, we utilize ordinary differential equations to generate a comprehensive and scientific model describing the diffusion of proton, the regulation of genes and the cell growth curve. We have successfully proved the feasibility of the project both in micro and macro. With its strengthened efficiency and robustness, this project can be applied not only to bioelectrogensis, but also to the design of biocell.

Disposition of polluted-water

One of the materials used in this project is the polluted acid or alkali water. Therefore, we can achieve polluted water treatment in this circuit by regulating the pathway of anaerobic respiration to generate electron which will react with proton. We can enhance the efficiency of disposing polluted water and get higher-efficiency engineering bacterium by redesigning some pathways of heavy metal absorption and organism degradation in E.coli.
In future application, this project can be applied to acid or alkali polluted-water treatment and electricity generation.

Utilization of biofilm

As we know, a lot of projects have been done to eliminate the effect of biofilm. However, in this project, we assume that we can construct anaerobic environment by means of biofilm and get anaerobic fermentation environment which can be utilized to activate certain path in the engineering bacteria, sequentially activate relevant function of the engineering bacteria and make better use of the biofilm.
