Abstract

The deoxyribonuclease activity was investigated in cell-free filtrates of cultures of strains of different transformability. The highly transformable stable strains display a relatively low, probably optimal, deoxyribonuclease activity. Transformable but unstable strains produce a very high deoxyribonuclease activity in comparison with the aforementioned ones. In some nontransformable strains no deoxyribonuclease activity could be detected. The role of deoxyribonuclease in the competence of recipient cells s discussed.
