title: [Effect of sodium dodecylbenzenesulfonate and antifoaming agents on the endonuclease activity of Serratia marcescens].
abstract: The effect of sodium dodecylbenzene sulfonate (sulfonol) and certain froth breakers on the activity of endonuclease was studied in the cultural broth of Serratia marcescens in order to find out whether sulfonol could be used for limiting the infection. Sulfonol was found to have no effect on the cultural growth; it increased the activity of endonuclease in the cultural broth, and the peak of the activity appeared earlier than in the control medium. Propanol B-400 was shown to be the best froth breaker.
