The pH and concentration of Ca2+ for optimum activity varied with the NaCl concentration; with an increased NaCl concentration, a higher Ca2+ concentration and a lower pH were required. V max, but not K max, varied with the concentration of NaCl. The addition of 3% (w/v) NaCl to growing cultures of S. aureus increased nuclease production fivefold., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-116-1-69
