This dual view on the biodiversityof sourdough will be discussed in this paper in the light of itsmicrobiological composition and metabolic interactions.Sourdough microorganismsLAB and yeasts are often associated in sourdough.TheLAB:yeast ratio in sourdoughs is generally 100:1 (Ottogalliet al., 1996).he process isperformed at ambient temperature (20â30 8C) and the pH isabout 4.0. Examples of baked goods so obtained are SanFrancisco sourdough French bread, Panettone and otherbrioches, Pugliese, Toscanon and Altamura bread, andthree-stage sourdough rye bread.
