In this work, the antimicrobial property of nanocomposite prepared by loading of silver nanoparticle onto activated carbon (AgNP-AC) was studied. The silver nanoparticles were synthesized biologically from the culture Enterobacter aerogenes and loaded onto the activated carbon. The nanoparticle and nanocomposite were characterized by UV-vis, scanning electron microscopy and X-ray diffraction studies. The spectroscopic assay and zone inhibition test for E. coli and B. subtilis clearly illustrates the antibacterial activity of the silver nanoparticle and nanocomposite. The antimicrobial activity was of the nanocomposite was also confirmed with the observed zone of inhibition against beverage, brewery, dairy and dye industrial effluents.
