Abstract

The adhesion of a meat Lactobacillus sp. to sausage collagen casing was substantially reduced (by 1-2 log CFU cm(-2)) in the presence of bovine serum albumin, casein, and a yeast cell wall mannoprotein. These proteins affected the [bacterium-medium-casing] system in several ways. They interacted with the cell wall surface, making it more positively charged, they lowered the surface tension of the adhesion medium, and they decreased the hydrophobicity of the casing. Reduction of bacterial adhesion appeared to be mostly related to the decrease in casing hydrophobicity and, indeed, the proteins which did not reduce adhesion (gelatin or casamino acids) had no effect on casing hydrophobicity. The fact that collagen reduced adhesion without affecting the casing surface free energy is consistent with the previous report that some lactobacilli can specifically bind to collagen through a receptor-adhesionsite interaction.
