Antimicrobial Activity of Purified Lipase-CuO Conjugate. Antimicrobial activities of Lipase-CuO nanoparticle conjugate against different microbial strains. (a) Escherichia coli, (b) Candida albicans (c) Bacillus subtilus, (d) Staphylococcus aureus, (e) Salmonella typhimurium, (f) Histogram of CuO- lipase conjugates antimicrobial activity against tested organisms. The results indicated the synergistic effect in conjugate represented by an increase in the diameter of inhibition zone particularly against E. coli strain NRC B-3703 with remarkable increase of 373.6% and 75% compared to that of individual CuO nanoparticles and lipase enzyme, respectively
