title: A medium for commercial production of the halophilic Micrococcus nuclease.
abstract: A simple synthetic medium (glutamate-sucrose medium) was devised for production, during growth in shaken flasks, of extracellular halophilic nuclease (nuclease H) by a moderate halophile, Micrococcus varians subsp. halophilus. A simple medium consisting of 0.7% ammonium sulfate, 1.0% glucose, minerals, three vitamins, and 2 M NaCl gave good growth and excellent production of nuclease H in a jar fermentor when the pH was adjusted to 7.5 to 8.0 during cultivation.
