Harmful algal bloom

Widespread water bloom leads to extensive damage in ecosystems. Compared to physical or chemical methods, biological treatment for water bloom is less expensive and more environmentally friendly. Hence Peking iGEM is dedicated to constructing engineered microorganisms for the elimination of algae and recovery of ecosystems. A specific antimicrobial peptide is secreted to disrupt the outer membrane of algae. In addition, we equip our transgenic cells with features that allow for buoyancy and attachment, making our project more efficient. During this process, an enzyme is also secreted to degrade a deleterious product of algae. After eradicating the algae, our engineered bacteria will commit suicide, and the ecosystem is finally restored. This project is an innovative treatment for water bloom, and has potential applications in the field of ecosystem remediation.
