The study introduces a sustainable method for creating copper nanoparticles (Cu NPs) using enzymes from a thermophilic bacterium, offering a greener alternative to traditional synthesis methods.
The production process utilized optimized conditions involving lignin peroxidase enzyme derived from peanut waste, emphasizing waste valorization and environmental benefits.
Characterization of the Cu NPs confirmed their stability and shape, and they demonstrated significant antibacterial activity against various pathogens, particularly showing effectiveness against Streptococcus pyogenes, which suggests potential uses in medicine and other fields.
