Comparative Antimicrobial Study of Probiotics Lactobacillus casie (CFS), Mint Extract and Common Detergent on Isolates from Currency Notes

Abstract The study finding indicates that Indian currency notes often harbor pathogenic microorganisms, thus possibly being vectors for infectious disease transmission. Samples of currency notes from different origins were analyzed and showed the presence of widespread contamination with pathogenic microorganisms. Interestingly, contamination was found to be less in bank notes compared with those acquired from other places. It further shows that lactobacilli and mint extract have higher antimicrobial efficiency than commercial detergents and sanitizers. Thus, these results indicate better hygiene practices in currency notes handling and also hint towards the capabilities of natural antimicrobial agents to reduce microbial contamination
