Summary
Engineered Paramecium caudatum (Para) with virus-scavenging organelles (VSOs) efficiently capture and deactivate waterborne viruses. These bioartificial organisms are reusable, offering a sustainable solution for water purification.
Area of Science:
- Biotechnology
- Environmental Science
- Microbiology
Background:
- Material-based strategies are crucial for evolving organism functions.
- Developing effective methods for waterborne virus removal is essential for public health.
Purpose of the Study:
- To engineer Paramecium caudatum (Para) into a steerable bioartificial organism for scavenging pathogenic waterborne viruses.
- To create a specific virus-scavenging organelle (VSO) within Para.
Main Methods:
- Integrated Fe3O4 magnetic nanoparticles (MNPs@Ab) modified with virus-capture antibodies into Para vacuoles.
- Engineered VSO-containing Para (E-Para) for specific virus capture and deactivation.
- Utilized the peroxidase-like activity of nano-Fe3O4 to generate hydroxyl radicals for virus inactivation in acidic VSO environments.
Main Results:
- E-Para specifically captured waterborne viruses without impairing motility.
- Captured viruses were confined and completely deactivated within the VSOs.
- Magnetized E-Para facilitated easy recycling and reuse, preventing secondary contamination.
Conclusions:
- Engineered Para (E-Para) functions as a living virus scavenger through materials-based artificial organelles.
- This approach offers a sustainable and energy-efficient method for waterborne virus clearance.
- The VSO system demonstrates the potential of biohybrid systems for environmental remediation.

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...
