Engineered Synthetic Microbial Consortia for In Vivo Plastic-Derived Metabolite Detoxification and Host Health Restoration in Ruminant Animals
Summary
Researchers proposed engineered synthetic microbial consortia for in vivo detoxification of plastic-derived metabolites in the rumen of cattle and goats, designing microbial communities capable of degrading plasticizers and other contaminants ingested through MP-contaminated feed.
Ruminant animals such as cows and goats face increasing health challenges from ingestion of microplastics and plastic-associated compounds contaminating their feed and grazing environment. These contaminants disrupt rumen microbial ecology, impair fermentation, and contribute to systemic toxicity, adversely affecting animal health and productivity. This hypothesis proposes engineering a synthetic consortium of rumen-adapted bacteria genetically modified to express a cascade of plastic-degrading and detoxifying enzymes capable of degrading plastic polymers and their metabolites within the rumen. By restoring ruminal fermentation homeostasis and reducing toxic bioaccumulation, this approach offers a scientifically logical, environmentally relevant, and practical solution to plastic pollution's impact on livestock.
