Fecha de publicación: -- Fuente: WIPO "tomato" The present disclosure relates to compositions, methods, and systems for reducing plastic, plastic-associated chemical, and/or environmental toxin accumulation in animals, including humans, through administration of microorganisms capable of binding to, sequestering and/or degrading plastics, such as microplastics and nanoplastics, plastic-associated chemicals, and/or environmental toxins. The compositions comprise single strains or defined consortia of bacteria, yeasts, or fungi - including Lactobacillus, Bifidobacterium, Lactococcus, Bacillus, Pediococcus, Enterococcus, Saccharomyces, and others - formulated in capsules, powders, tablets, functional foods, or feed additives. Mechanisms include direct binding, aggregation, enzymatic depolymerization, biosurfactant secretion, and neutralization of plastic-associated chemicals and/or environmental toxins (e.g., bisphenol A, phthalates, PFAS, metals). Delivery systems employ acid-resistant capsules and fiber co-matrices to enhance fecal elimination. Methods further include diagnostic monitoring and personalized recommendation engines, enabling long-term mitigation of cumulative plastic and environmental toxin burden.
