The bacterium was isolated by a multidisciplinary team exploring microbial metabolism in environments rich in battery discharge products. Their research revealed that this organism not only survives but metabolically processes the metal ions left behind in used battery cells, converting them into secondary compounds that may be reused in manufacturing.
According to the researchers, such microbial processes could form the basis of a new bio-recycling framework that extracts and reuses valuable elements like lithium, cobalt, and nickel while minimizing environmental harm. The team envisions scalable bioreactors capable of continuously cycling metals through biological recovery systems, thereby reducing waste and cutting energy use.
The findings open a new frontier in green chemistry by pairing biotechnology with materials recovery science. The study team noted that this approach may lead to self-sufficient recycling operations where bacteria autonomously regenerate usable metals from spent devices, potentially transforming global recycling pipelines.
"Microorganisms have evolved abilities that can directly support industrial sustainability," one researcher said. "Harnessing those processes could allow us to reimagine the entire battery recycling industry."
