Abstract

The effect of aw and three polyol humectants, glycerol, propylene glycol and butylene glycol on the production of heat‐stable staphylococcal nuclease by S. aureus 196E was examined. Nuclease enzyme activity as detected by the DNA‐agar‐diffusion technique was related to the growth pattern in various test conditions. Of the conditions tested, 20% glycerol (0.95 aw), 10% proplyene glycol (0.97 aw), and 10% butylene glycol (0.98 aw) were shown to result in a reduced rate of nuclease production per unit cell, when compared to conditions of higher water activity.
