Antimicrobial Effect of Sodium Nitrite and Sodium Chloride in Nutrient Broth or Ground Pork Meat

Effect of sodium nitrite, sodium chloride , and sodium nitrate on germination and outgrowth of anaerobic spores.

The effects of meat-curing agents on germination and outgrowth of putrefactive anaerobe 3679h (PA 3679h) spores were studied in microcultures. Nitrite concentrations up to 0.06% at pH 6.0 or between 0.8 and 1% at pH 7.0 allowed emergence and elongation of vegetative cells but blocked cell division. The newly emerged cells then lysed. With more than 0.06% nitrite at pH 6.0 or more than 0.8 to 1%...

Effect of pH, sodium chloride, and sodium nitrite on enterotoxin A production.

The combined effects of pH, sodium chloride, and sodium nitrite were studied by using a dialysis sac technique in brain heart infusion broth. Growth and enterotoxin A production by Staphylococcus aureus strain 100 were found to decrease with the addition of sodium nitrite, with a decrease in pH from 7.0, and with an increase in sodium chloride concentration. The significance of these results is...

The Use of Sodium Nitrite in the Curing of Meat

The art of preserving meats by curing in common salt, with or without smoking, is one which has been practiced from remote antiquity. Directions for curing meats with salt appear in ancient writings, and the art is still practiced among primitive peoples. Yet, notwithstanding the antiquity of the art and its economic importance, adequate and comprehensive scientific study with publication of re...
