Scanning electron microscopy of hyphal ectobiont bacteria within mycelial extracellular matrices
mycolabadmin
Researchers studied how bacteria (Bacillus subtilis) attach to mushroom fungi (Lion’s Mane/Hericium erinaceus) in liquid cultures. Using a special drying technique and electron microscopy, they were able to see tiny structures where bacteria stick to the fungal threads. These structures are made of slimy substances produced by the fungus and could potentially allow bacteria to influence the fungus’s electrical and physical properties.
