title: 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.
