ANTIMICROBIAL PROPERTIES OF LANTHANUM ALUMINATE NANOPARTICLES

The sol-gel route synthesized LA-NPs were tested for antimicrobial properties against different human pathogenic bacteria and fungi. The test organisms used were clinical isolates viz., Streptococcus pyogenes, Staphylococcus aureus, Escherichia coli, Klebsiella nemoniae and the human fungal pathogens like Candida albicans and Trichoderma viride. The LA- NPs achieved maximum activity against S. aureus compared with other three tested organisms such as S. pyogenes, E. coli and K. pneumonia. It also showed very good antimicrobial properties against studied fungi. At the concentration 1 mg/ml LA-NPs impregnated filter paper disk achieved maximum activity against human pathogen.
