Throughout history and into the future, humanity's pursuit of space exploration has never faltered.

From the Moon to Mars and on to the farthest reaches of space, what will be humanity's enduring support?

The depletion of resources and the finite nature of energy in spacecraft are pressing issues that must be resolved for long-distance space voyages.

The millennia-old rice-fish symbiosis system in China presents a novel idea for us.

In this system, rice and weeds provide shelter and organic nourishment for the fish, which in turn aerate the soil, control weeds, consume pests, and transform their waste into nutrient-rich fertilizer.

In space, astronauts can consume cultivated crops, but they lack a controllable and efficient system of decomposers to return materials back to the ecosystem.

We selected Shewanella as the biological chassis.

It can generate electricity, creating possibilities for energy conversion. With our modifications, it also has the capability to accumulate phosphorus, making it a potential source of phosphate fertilizer.

In this system, humans harvest food from crops, while Shewanella extracts phosphorus from human and corp waste, generating electricity and providing fertilizer for the next cycle of crop growth.

By integrating engineered Shewanella, we have established a loop of material recycling and energy recovery.
