Fructilactobacillus sanfranciscensis is a heterofermentative species of lactic acid bacteria which, through the production mainly of lactic and acetic acids, helps give sourdough bread its characteristic taste. It is named after San Francisco, where sourdough was found to contain the variety, though it is dominant in Type I sourdoughs globally.
The sourdough starter was passed down to 10-year-old Carl Griffith in about 1930 in a Basque-American sheep camp. His family was building a homestead in the Steens Mountains at the time, and he baked bread in a Dutch oven in a campfire-heated pit. Griffith took his starter on cattle drives in southeastern Oregon, during which he baked in chuck ...
When maintaining a starter's existing weight, it is advised to discard 60% (or more) of the starter, replacing that discarded dough with new dough. If an increased amount of starter is required, simply add new dough. 40-parts-to-60-parts of old-dough-to-new-dough by weight, or 2-to-3, is known as the back-slopping ratio, and changes to that ...

While getting a desem starter (a dough starter) going the first time can be challenging, keeping it going can be easier than sourdough starters (liquid starters). [ 5 ] Feeding the starter daily and baking bread once per week is the standard method of keeping the desem starter happy and thriving [ 6 ] but feeding it weekly or freezing it for ...
In sourdough bread-making, cold decreases the activity of wild yeast relative to the Lactobacilli, [13] which produce flavoring products such as lactic acid and acetic acid. [14] Sourdough that is retarded before baking can result in a more sour loaf. To prevent the dough from drying, air flow in the dough retarder is kept to a minimum.
