Gold-Producing Microbe Discovered, Offering Environmental Benefits
Imagine a tiny creature that lives in places filled with poisonous metals.
This special bug, found by scientists, eats these metals and poops out tiny bits of real gold!
It does this to protect itself from the poison.
The bug produces special helpers called enzymes that turn the metal into gold particles.
Scientists are excited because they think they can copy this bug to get gold from old electronics and leftover mining materials in a cleaner, cheaper way.
This could help clean up the environment and turn trash into treasure.
A microbe called Cupriavidus metallidurans converts toxic metals into 24-carat gold.
This microbe was discovered by researchers from Australia and Germany.
The microbe uses a defense mechanism to survive in toxic, metal-rich environments.
Special enzymes produced by the microbe transform gold ions into nanoparticles.
Scientists hope to use this process to extract gold from electronic waste and mine tailings.
