Characteristics of heat-stable extracellular hemolysin from Pseudomonas aeruginosa

Abstract

Heat-stable hemolysin produced by the cellophane-agar plate method consisted of two major acidic glycolipids. One was composed of 2 mol of rhamnose and 2 mol of β-hydroxydecanoic acid, and the other was composed of 1 mol of rhamnose and 2 mol of β-hydroxydecanoic acid. The hemolysis-producing moiety of the hemolysin was shown to be the dimer of β-hydroxydecanoic acid contained in the glycolipid molecule.
