Enhancement Antimicrobial Activity of Hyphothiocyanite using Carrot Against Staphylococcus aureus and Escherichia coli

Abstract

Hypothiocyanite has been known as antimicrobial agent that was generated from lactoperoxidase system (LPOS) but its antimicrobial activity was low against pathogenic bacteria in milk. This research has been done to enhance the antimicrobial activity of hypothiocyanite against pathogenic bacteria commonly found in milk: Staphylococcus aureus and Escherichia coli by addition of carrot extract. The result showed that carrot extract was able to enhance the antimicrobial activity of hypothiocyanite strongly against E. coli, however less enhancement has been found in the antibacterial activity of hypothiocyanite against S. aureus.
