Lactic Acid Bacteria: Prevalence
The live microorganisms that inhabit sourdough starters are responsible for the unique aspects of sourdough bread, including its flavour and extended shelf life.
To make a sourdough starter, you mix just 2 ingredients: flour and water. After a few days, a symbiotic microbial community blooms, ready to help create a loaf of sourdough bread. Each starter contains a unique blend of microbes that create a “secret sourdough bread recipe” — secret not only to the baker, but also to those they share it with or pass it down to through the generations.
Scientists know that certain kinds of bacteria and yeast populate sourdough starters, but because each sourdough starter is unique, we still cannot say exactly which microbes make up the sourdough microbiome. Much like the deep sea with so many organisms yet to be discovered, so too sourdough starters contain many unknown microbes. In light of World Microbiome Day (June 27, 2020), here’s the state of our knowledge about the sourdough microbiome…
