Abstract
Through a series of chemical fractionation steps, the extracellular hemolysin of Pseudomonas aeruginosa was purified 126-fold with a recovery of 49%. Hemolytic activity of crude preparations was irreversibly lost upon contact with anionic exchange materials such as diethylaminoethyl Sephadex or ECTEOLA-Cellulose, but traveled with the solvent front during passage through Sephadex G-200 and carboxymethyl Sephadex. The hemolysin was soluble in water and ethanol, and was partially extractable with ether, but not with trichlo-rotrifluoroethane (Freon). Although normal serum and serum albumin blocked hemolytic activity, it was unaffected by trypsin, deoxyribonuclease, or ribonuclease. Partially purified hemolysin was studied in vivo, but did not exert dermonecrotic activity in mice or rabbits in the concentrations tested. Although preparations were toxic to mice, lethality appeared to be more a reflection of the non-hemolytic protein content of the preparations rather than of hemolytic activity.Keywords
