Evaluation of two autoinducer‐2 quantification methods for application in marine environments

This study evaluated two methods, namely high performance liquid chromatography with fluorescence detection (HPLC‐FLD) and Vibrio harveyi BB170 bioassay, for autoinducer‐2 (AI‐2) quantification in marine samples. Using both methods, the study also investigated the stability of AI‐2 in varying pH, temperature and media, as well as quantified the amount of AI‐2 signals in marine samples.
