About 1/4 of the world's population still lacks safe drinking water. It is estimated that by 2050, 1/2 of the world's population will face severe water shortages.
Among them, some pollutants are difficult to degrade with conventional chemical methods, such as heavy metals, chemical pesticides, and antibiotics. Microbial bioremediation has shown significant application prospects in the treatment of these pollutants.
However, in practical applications, engineered bacteria have problems such as easy loss, poor stability and low cell density.
With the development of technology, a large number of environmental pollutants are discharged, and 0 of sewage are discharged into the world's waters every day, and the water environment is rapidly deteriorating.
In terms of water pollution, organic pollutants, heavy metals, nitrogen and phosphorus compounds are the most important pollutants.
Engineered bacteria offer significant potential for environmental remediation, particularly in sewage treatment.In practical applications，including detection, adsorption, and degradation of pollutants.
We fix Bacillus subtilis on the surface of solid materials by modifying the TasA protein on the surface of Bacillus subtilis to prevent it from dispersing in sewage.
To verify the functionality of TasAnchor, we tried to apply it to the treatment of Cd2+ contamination, including detection, adsorption, and elution of Cd2+.
We also designed a suicide switch system to allow Bacillus subtilis to kill when it leaves the platform to improve the safety of TasAnchor.
