Our team expressed pcrABCD and accessory proteins in the periplasm to reduce perchlorates in E. coli with lipoprotein knockouts.


However, its regolith is full of perchlorates — a toxic compound that prevents plant growth and endangers human health.

Planetary Removal of Soil Perchlorates and Enrichment Remediation!

We developed a co-culture system with E. coli and Synechococcus PCC 7002 that creates a closed loop, recycling perchlorate byproduct into organic carbon.
To provide a feasible, user-friendly, and energy-efficient deployment platform for this co-culture system, we developed a fully modular and highly adaptable bioreactor family — ARC.


We first used a soil flow-through system to wash out perchlorate with water. Then, we utilized ARC to immobilize bacteria into biofilm and complete degradation in the treatment chamber.

To learn more about methodologies, perchlorates, and the ethics behind space travel, we interviewed researchers, doctors, and policy experts.

We hosted educational events for children, adults, and elders to spread awareness about space travel and its ethics.
PRoSPER’s growth can be driven by future space exploration and the increasing focus on legacy perchlorate contamination on Earth.
