• nanoparticles (ZnO NPs), utilizing lactic acid bacteria isolated from curd as the key biological agent. Bacteria function as agents for both reduction and capping processes, which aids the synthesis of ZnO NPs. Various characterization techniques including XRD, FTIR, UV–vis, TEM, SEM-EDX, and zeta potential

• applications. Keywords: anticancer; green synthesis; lactic acid bacteria; nanoparticles; zinc oxide; Introduction Nanotechnology has revolutionized various fields through its remarkable development and the unique properties exhibited by nanoparticles (NPs) at the mesoscopic level.

• biomedical applications. This work reports on the green synthesis of ZnO NPs employing lactic acid bacteria (LAB) as capping and reducing agents to produce biocompatible NPs for use in pharmaceutical and biological applications [3][4][5]. LAB are Gram-positive, catalase-negative, and non-pathogenic bacteria
