The effects of broad spectrum pulsed light on the survival of Listeria monocytogenes Scott A, Listeria monocytogenes CNL, Pseudomonas fluorescens MF37 and Photobacterium phosphoreum SF680 populations on agar and in a liquid medium were investigated during this study. The sterilisation system generated 1.5 J cm(-2) per pulse with eight lamps for 300 mu s. In the case of surface-seeded cells, a 7.8, 8.14 and > 7.14 log reduction was obtained for L. monocytogenes, Ps. fluorescens MF37 and Ph. phosphoreum, respectively, after a single pulse of treatment. Inactivation levels were lower for depth-plated cells: indeed, 10 pulses of treatment achieved 1.6, 2.03 and 4.78 log reductions for L. monocylogenes ScottA, L. monocytogenes CN-L and Ps. fluorescens MF37, respectively. After 5 pulses, Ph. phosphoreum exhibited a 4.6 log reduction. Similarly, bacterial cells in suspension treated with 3 pulses were reduced by 0.52, 0.8, 2.07 and 2.05 for L. monocytogenes ScottA, L. monocytogenes CNL, Ps. fluorescens MF37 and Ph. phosphoreum, respectively. No resistance to pulsed light was observed during our experiments.
