Simple sonochemical method was used for synthesis of nano sized particles of Calicum Oxide (CaO) in ethylene glycole solution in the presence of Tirton X-100 as a surfactant. Nanoparticles of precipitate of Ca(OH)2 was formed by the addition of NaOH slowlyto the calcium ion solution under ultrasonic radiation for 30 minutes, then followed bycalcination for 5500C. The formed nanoparticles were characterized by SEM, XRD, Uv-Vis, and FTIR spectroscopy. It was observed that the size of the nanoparticles was around 30-50 nm. The lethal effects of nanocrystalline CaO were evaluated on Lactobacillus plantarum. At a concentration of 100 ppm, the killing effect of MgO was close to 1 log reduction for L. plantarum after 24 h exposure.
