  Losing Lactobacillus was part of why compostable plastic particles damaged mouse livers

  Polylactic acid, the compostable plastic used in food packaging, sheds nanoparticles when hot water is added to powdered food. Combined with the silica already in those powders, it damaged mouse liver and gut more than either did alone, and transplant experiments traced part of that damage to the loss of Lactobacillus.

  A bacterium from kimchi held onto nanoplastic across every gut condition the authors tried

  Leuconostoc mesenteroides CBA3656, isolated from kimchi, adsorbed nanoplastics across a wide range of concentrations, acidities and temperatures, and held up in fluid formulated to mimic the small intestine. Mice given the strain excreted significantly more plastic in their faeces.
