Kind: research · Impact: low

## In brief

- Researchers at the University of Valladolid in Spain used a type of purple bacteria to produce CoQ10 and carotenoid pigments.
- The process uses CO₂ and other industrial waste products as inputs.
- The products are described as valuable ingredients for dietary supplements.

## Why it matters

The work shows that waste carbon streams could be converted into supplement ingredients by microbial production, a possible route to lower-waste manufacturing.
