How engineered microbes could help feed the world’s crops

Summary

Engineered microbes offer a potential solution to reduce the environmental impact of synthetic fertilizers. Companies like Switch Bioworks and Pivot Bio are developing microbial fertilizers that can fix nitrogen for crops, aiming to decrease reliance on energy-intensive synthetic options. While promising, widespread adoption and full replacement of synthetic fertilizers are still several years away and require extensive field validation.

Key Takeaways

1. Engineered microbes are being developed to provide nitrogen for crops, potentially reducing reliance on synthetic fertilizers.
2. Companies like Switch Bioworks are developing genetic switches to control when microbes produce nitrogen, addressing challenges of energy expenditure for the microbes.
3. While promising, the technology is still in trials and commercial products are several years away, with potential to replace only a portion of synthetic fertilizer.
