Screening of Antifungal Lactic Acid Bacteria and Their Impact on the Quality and Shelf Life of Rye Bran Sourdough Bread.

ABSTRACT: In the present study, Lactiplantibacillus plantarum G8, exhibiting higher antifungal activity, and G12, displaying weaker antifungal activity, were isolated from naturally fermented wheat sourdough. Their impacts on bread quality and shelf life were subsequently investigated. The results demonstrated that both strains exhibited robust growth in rye bran sourdough. Compared to the blank control rye bran-wheat flour dough (RB dough), sourdough incorporation enhanced percentages of β-sheet and α-helix secondary structures, facilitating the formation of a more ordered gluten network structure. This contributed to reduced bread baking loss and decreased bread hardness, gumminess, and chewiness, with Lpb. plantarum G8 exhibiting the most pronounced effects. Notably, G8 bread displa
