A starter culture is a microbiological culture which actually performs fermentation. These starters usually consist of a cultivation medium, such as grains, seeds, or nutrient liquids that have been well colonized by the microorganisms used for the fermentation.
To make enough starter for one loaf, combine 3 tablespoons (1/4 cup) pastry flour, bread flour or all-purpose flour and 3 tablespoons, plus 1 teaspoon of water in a dish that can be easily covered ...
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 ...
In this usage, synonyms for sponge are yeast starter or yeast pre-ferment. [3] [note 1] In French baking the sponge and dough method is known as levain-levure. [4] The method is reminiscent of the sourdough or levain methods; however, the sponge is made from all fresh ingredients prior to being used in the final dough. [5] [note 2]
In biology, a subculture is either a new cell culture or a microbiological culture made by transferring some or all cells from a previous culture to fresh growth medium. This action is called subculturing or passaging the cells. Subculturing is used to prolong the lifespan and/or increase the number of cells or microorganisms in the culture. [1]
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
A SCOBY used for brewing kombucha Kombucha co-culture with SCOBY biofilm. Symbiotic culture of bacteria and yeast (SCOBY) is a culinary symbiotic fermentation culture consisting of lactic acid bacteria (LAB), acetic acid bacteria (AAB), and yeast which arises in the preparation of sour foods and beverages such as kombucha.

A loaf of bread baked with Carl Griffith's sourdough starter sits on a board. Carl Griffith's sourdough starter, also known as the Oregon Trail Sourdough or Carl's starter, is a sourdough culture, a colony of wild yeast and bacteria cultivated in a mixture of flour and water for use as leavening.
