Retention of <i>Listeria </i>and <i>Salmonella </i>cells contaminating skim milk by tangential membrane microfiltration ("Bactocatch" process)

Abstract

Retention by tangential membrane ultrafiltration of non-virulent Listeria and Salmonella cells whose morphological and physiological characteristics were close to pathogenic strains was studied. The bacteria were added to raw milk, pasteurized milk or previously microfiltered milk.
