Bioengineering allows scientists to harness evolution-honed biological processes for drug and chemical production. Tufts researchers have now identified new ways to use bacterial spores as catalysts for chemical reactions, biofuel production, and pollutant breakdown.
This work builds on the natural resilience of spores, which can survive extreme conditions and remain dormant for long periods. By engineering them, scientists can potentially create stable, reusable biocatalysts without the fragility of traditional enzymes.
The study did not specify numerical improvements in catalytic efficiency or yield. However, the approach highlights how spore surfaces can display functional proteins, enabling applications from environmental cleanup to vaccine development.
If scalable, this technique could reduce costs in industrial bioprocessing and allow on-demand activation of biological agents. Pollutant degradation and biofuel production are immediate candidates for real-world testing.
Researchers emphasize that further work is needed to optimize spore engineering for commercial viability. The findings provide a foundation, not a finished product.
