''Lactobacillus sanfranciscensis'' (formerly ''L. sanfrancisco'') is a species of lactic acid bacteria that helps give sourdough bread its characteristic taste. It is named after San Francisco, where sourdough was found to contain the variety, though it is not endemic to the area. Sourdough starters are leavened by a mixture of yeast and lactobacilli in a ratio of about 1:100. The yeast is most commonly ''Candida humilis''. This yeast cannot metabolize the maltose found in the dough, while the ''Lactobacillus'' needs maltose. They therefore act without conflict for substrate, with the ''Lactobacillus'' utilizing maltose and the yeast utilizing the other sugars, including the glucose produced by the ''Lactobacillus''. For commercial use, specific strains of the ''L. sanfranciscensis'' are grown on defined media, freeze-dried, and shipped to bakeries worldwide. ==References== 〔
