Synergisitc inhibition of Listeria monocytogenes on cold smoked rainbow trout by nisin and sodium lactate. International Journal of Food Microbiology. 61 (2000) 63-72. Rainbow trout with 15g/kg salt injected with 36g/kg sodium lactate, 240 IU/g Nisinora combination of 18g/kg sodium lactate and 120 IU/g Nisin, cold smoked then held 30 days at 37.4°F (3°C). In all treatments L. monocytogenes grew. The combination of lactate and Nisin only allowed 0.1 log growth in the 30 days, Nisin alone allowed 1.2 log growth and lactate allowed 1.3 log growth as compared to no treatment which showed 1.8 log units of growth.
