Scientists discover nuclear waste-eating bacteria

The video explains how radioactive waste is encased in concrete and stored in underground vaults. Groundwater can react with the concrete, creating an alkaline environment that produces isosaccharinic acid (ISA). ISA can increase the solubility of radioactive materials, potentially allowing them to escape the vaults. However, scientists have discovered extremophile bacteria that thrive in these conditions and consume ISA, potentially preventing the spread of radioactive waste into the environment.

What role do extremophile bacteria play in the context of radioactive waste?

How might ISA help in preventing radioactive waste from seeping into the environment?
