What's Happening?
Research published in Bioresource Technology suggests that the bacterium Leuconostoc mesenteroides CBA3656, found in kimchi, can bind to nanoplastics in the gut, potentially aiding in their expulsion.
The study, led by Dr. Se Hee Lee and Dr. Tae Woong Whon, tested the bacterium in lab conditions, mimicking the human intestines, and in mice. The bacterium demonstrated a strong ability to bind to nanoplastics, a promising finding given the ubiquity of microplastics in food and water. The research indicates a potential probiotic approach to reducing plastic accumulation in the body.
Why It's Important?
This research is significant as it addresses the growing concern of plastic pollution, not only as an environmental issue but also as a public health concern. The ability of a food-derived bacterium to bind to nanoplastics suggests a new biological approach to mitigating plastic accumulation in the body. If successful in human trials, this could lead to new dietary recommendations or probiotic treatments to combat the health risks associated with microplastics. The study also highlights the potential of microorganisms from traditional fermented foods in addressing environmental pollutants.
What's Next?
While the findings are promising, further research is needed to confirm the bacterium's effectiveness in humans. Human trials will be necessary to determine if the results observed in lab conditions and mice can be replicated in the human body. The research team, affiliated with the World Institute of Kimchi, plans to continue exploring the scientific value of kimchi microbial resources. This could lead to new public health and environmental solutions, although potential conflicts of interest due to the researchers' affiliations should be considered.
