Description
Although the war between desertification and human beings has never been halted, the existing methods are highly time-consuming and funds-costing such as physical approaches with straw barriers and chemical ones with surface immobilization. To change the situation, we are to develop a novel biological way with the technology and theory based on Synthetic Biology: Produce a engineered strain immobilizing sands and preventing evaporation of water to delay the process of desertification.

Project
- Develop an engineered strain which can secrete colonic acid(one kind of exopolysaccharides preventing water vaporing and forming soil aggregation) using E.coli as the microbe chassis
- Release different amount of colonic acid according to temperature changes
- Produce a novel biological bacterial fertilizer with this engineered strain
- Develop a general secreting system which can be used under different microbe chassis.
