Abstract Most strains of Lactobacillus casei tested were found to be nisin-resistant. The addition of nisin to a growing culture of a resistant strain stopped growth for several hours; however, growth then resumed at the previous rate. Nisin induced a resistance mechanism that was lost by one passage in nisin-free medium. During induction with nisin, the cells produced an anionic, phosphate-containing polysaccharide with the subunits rhamnose and galactose. This polysaccharide protected sensitive cells of L. casei against the bactericidal action of nisin.
