Seeds cleaning water--bottles

Seeds cleaning water--bottles

Bottles with cloudy water and water cleaned by Moringa seeds

Both bottles originally contained turbid, contaminated water. The bottle on the left was treated with crushed Moringa seeds. A protein in the seeds killed bacteria in the water and made them clump together and fall to the bottom of the bottle. However, this water will not be safe to drink for long because organic matter remaining in the water can serve as food for other bacteria. A technique developed by Penn State scientist Stephanie Velegol reduces this concern and provides water that remains safe to drink for a longer time.
