This study investigated the impact of CdS nanoparticles (NPs) on growth and metabolism under varying conditions. Under illumination, CdS NPs significantly enhanced bacterial growth, glucose assimilation, and biomass accumulation. Key metabolic and stress response genes showed increased expression, indicating improved ATP synthesis and oxidative stress resistance. Additionally, CdS NPs enhanced the electrochemical properties of , promoting efficient electron transfer. No significant changes were observed in the dark. These findings suggest that light-activated CdS NPs promote growth and metabolic efficiency by upregulating crucial genes involved in growth and oxidative stress management.
