Abstract

A whole-cell biosensor based on prodigiosin was developed for Hg(II) detection by screening four PigC homologs. The optimized sensor exhibited a detection limit of 0.41 nM, absolute selectivity against competing metal ions, and robust performance in tap, lake, and seawater matrices, providing a sensitive platform for environmental mercury monitoring.
