Detection of live-dead bacteria by confocal microscopy. Observation by confocal microscopy of L. brevis IOEB 9809 after gastric stress to pH 5.0 in absence of BA precursors (A) or in presence of: agmatine (B), tyrosine (C) or agmatine plus tyrosine (D). Green cells represent live bacteria, while red cells are bacteria with damaged membrane.
