Does salt really slow yeast fermentation?

Bread & Fermentation

The supplied evidence does not directly show that salt slows yeast fermentation. In a cucumber-fermentation study, fermentation with and without sodium chloride produced similar chemical changes, but the abstract does not identify yeast or test ordinary yeast fermentation specifically.

Salt can affect microorganisms, but its effect depends on the salt concentration, the organism, and the food or liquid being fermented. The most relevant supplied study found that cucumber fermentation without sodium chloride followed the same broad pattern as fermentation with sodium chloride and that the two processes were chemically similar. However, this was a food-fermentation study, not a direct experiment on yeast fermentation, so it cannot establish whether salt slows yeast in bread, beer, or another yeast-based system.
