Relation of Lipopolysaccharide and Fatty Acid Ester Release to the Ethylenediaminetetraacetic Acid Alteration of Permeability in Enterobacteriaceae

Abstract

Escherichia coli subjected to cold osmotic shock released 30 to 40% of their fatty acid esters and 42% of their cellular hexosamine. In contrast, Enterobacter, although they released 40% of fatty acid esters, release only 25% of hexosamine. Proteus released less than 15% of either fatty acid esters or hexosamine. These differences are taken to explain the differences among the Enterobacteriaceae in releasing surface enzymes after osmotic shock. It is felt that the release of additional lipopolysaccharide after osmotic shock is necessary for the release of surface enzymes that are not freed by ethylenediaminetetraacetic acid-tris(hydroxymethyl)aminomethane exposure.
