Vegetative cells of Bacillus cereus were subjected to
low doses of nisin (0.06 µg/ml) and mild pulsed-electric field
treatment (16.7 kV/cm, 50 pulses each of 2-µs duration). Combining
both treatments resulted in a reduction of 1.8 log units
more than the sum of the reductions obtained with the single
treatments, indicating synergy.
