It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance. Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species. Methanothrix harundinacea and Methanosarcina horonobensis retrieve electrons from Geobacter metallireducens via direct interspecies electron transfer (DIET). https://hollandscountryclothinges.shop/product-category/first-aid-kits/
