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

Abstract

This study evaluated the antibacterial activity of Biosecur®citrus extract surface cleaner againstVibrio vulnificususing plate count method. Two concentrations, 0.5% and 2% of Biosecur®surface cleaner were plated onVibrio vulnificusAgar (VVA) and tested for reduction ofVibrio 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 ofVibrio vulnificusat 2%, and 3-log reduction ofVibrio vulnificusat 0.5%. The antibacterial activity of 2% Biosecur®againstVibrio vulnificuswas 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.
