Identification of a Wheat Thaumatin-like Protein That Inhibits .

Plants often produce antifungal peptides and proteins in response to infection. Also wheat, which is the main ingredient of bread dough, contains such components. Here, we show that while some industrial strains of the baker's yeast can efficiently ferment dough, some other strains show much lower fermentation capacities because they are sensitive to a specific wheat protein.

Bread Dough and Baker's Yeast: An Uplifting Synergy.

Yeast-mediated dough fermentation is an important phase in the bread making process. The fermentative performance of yeast cells during fermentation is of critical importance for final bread quality, since yeast cells produce CO and other metabolites that have an influence on dough rheology and bread texture, volume, and taste. Different factors affect the fermentative performance of yeast cells during dough fermentation, including dough ingredients, fermentation conditions, the type of yeast strain used and yeast pregrowth conditions.
