Abstract

A lysozyme from Bacteriophage 7v was purified 7.7 fold over the original lysates of the bacteriophage 7v and Pseudomonas aeruginosa PS-7. This purification process includes ultracentrifugation, ammonium sulfate precipitation, dialysis, and fractionation in a Sephadex G-150 column. The phage lysozyme exhibits a greater specificity when assayed with P. aeruginosa cells as a substrate, but still is capable of acting on the standard lysozyme Micrococcus lysodeikticus substrate. The pH optimum, heat inactivation range, and action on other bacteria is described. The molecular weight was found to be 14,300. The values of this 7v phage lysozyme are in close agreement with values found with other phage lysozymes. A possible treatment for burn wounds infected with Pseudomonas aeruginosa is also described.
