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

The Open Microbiology Journal 8 Nov 2013 RESEARCH ARTICLE DOI: 10.2174/1874285801307010130


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.
