Antibacterial Activity of Biosecur^® Citrus Extract Surface Cleaner Against Vibrio Vulnificus

Abstract

This study evaluated the antibacterial activity of Biosecur^® citrus extract surface cleaner against Vibrio vulnificus using plate count method. Two concentrations, 0.5% and 2% of Biosecur^® surface cleaner were plated on Vibrio vulnificus Agar (VVA) and tested for reduction of Vibrio vulnificus. In order to investigate the lasting residual activity of Biosecur^®, antibacterial activity tests were also performed at time intervals up to 2.5 h after Biosecur^® was plated on VVA. Biosecur^® showed 6-log reduction of Vibrio vulnificus at 2%, and 3-log reduction of Vibrio vulnificus at 0.5%. The antibacterial activity of 2% Biosecur^® against Vibrio vulnificus was shown to be equivalent to that of tetracycline. The residual activity of 2% Biosecur^® was shown to maintain for at least 2.5 h after application. This study confirmed the high activity and long lasting residual effect of a safe, non-toxic organic food grade surface cleaner.
