Eradicating Aquatic Biocontaminant Blooms With a Novel, Stabilized Ozonated Glycerol Antimicrobial
CWSF · 2026 Environment & Climate Change Silver Medal
Overview
Water biocontamination is a global health crisis. The microbial blooms in biocontaminated water cause many different infectious diseases and lead to over 1.7 million annual deaths worldwide. To address this problem, a novel ozonated glycerol antimicrobial treatment was employed. In this project, the bloom-eradication capacity of the antimicrobial was quantified using five distinct assays. Several different strains of microbial biocontaminant blooms were assessed for viability: blooms engineered to varying treatment-resistance capacities using CRISPR-Cas9, and blooms collected from local water sources. Results revealed statistically significant eradication of the biocontaminant blooms by the mechanism of apoptosis: programmed cell death. These findings are important as they identify this ozonated glycerol treatment as a novel, antimicrobial, chemically stable and non-toxic means of removing biocontaminants from drinking water.
