Wild yeast is also called Saccharomyces exiguus (also known as S. minor).

A bread starter is the base for many artisan breads including sourdough and Amish Friendship Bread. It uses naturally occurring wild yeast to raise bread, lending a distinct flavor and texture to the bread which cannot be replicated by commercially harvested yeast.

3 bread starters: sourdough starter,sponge starter.

The starter can be used in a recipe, but must be activated so it is vigorously bubbling before using in a recipe.By making a "starter" in which wild yeast can grow, the sourdough baker can raise bread naturally.
