Magnetotactic bacteria (MTB) synthesize intracellular magnetic nanocrystals called magnetosomes. which are composed of either magnetite (Fe3O4) or greigite (Fe3S4) and covered with lipid membranes. The production of magnetosomes is achieved by the biomineralization process with strict control over the formation of magnetosome membrane vesicles. uptake and transport of iron ions. https://wholelatteslovers.shop/product-category/syrups-and-sauces/
