From the mature sourdough (12). Offered these numerous elements, the diverse taxonomy and metabolism that characterize sourdough yeasts and, especially, lactic acid bacteria aren’t surprising (13, 14). Among the technological parameters, the dough yield (DY [flour weight water weight] 100/flour weight) markedly influences the progress and outcome of sourdough fermentation, because of the effect on microbial diversity (12, 15). Due to the fact flours have diverse capacities to absorb water, DY primarily bargains with dough consistency and measures the quantity of water made use of within the dough formula. The higher the amount of water, the larger the value of DY, which has an influence on the acidity in the sourdough (15) and, slightly, around the values of water activity (15, 16). Variety I, or regular, sourdough is generally made from firm dough, with DY values of ca. 150 to 160.

In view of this technology modify, some troubles have to be addressed. How will be the diversity and stability with the microbiota influenced through the switch from firm to liquid sourdough and, consequently, does the liquidsourdough fermentation create precisely the same biochemical and sensory features as firm circumstances Furthermore, an extremely handful of studies (21, 22) have viewed as the impact of DY around the diversity of the sourdough microbiota, and none employed the approach of this study and supplied indepth microbial and biochemical characterization. This study viewed as four firm and mature sort I sourdoughs, which have been propagated day-to-day for 28 days beneath firm and liquid conditions to mimic the technology.
