The main type of bacteria used in the production of sauerkraut is of the genus Leuconostoc. [1] [16] As in yogurt, when the acidity rises due to lactic acid-fermenting organisms, many other pathogenic microorganisms are killed. The bacteria produce lactic acid, as well as simple alcohols and other hydrocarbons.
Leuconostoc lactis is a Gram-positive, non-motile, lactic acid bacterium that thrive best in acidic conditions and moderate temperatures. [2] [1] L. lactis is capable of acidifying culture media through lactose fermentation to pH levels of 4.0-4.1, and milk to levels below 5.4. [4]
MICROORGANISM TYPE ( Bacterium / Fungus ) FOOD / BEVERAGE Acetobacter aceti: bacterium: chocolate [1]Acetobacter aceti: bacterium: vinegar [2]Acetobacter cerevisiae
MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. [1] Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color.
It is the type of bacteria that convert lactose into lactic acid in yogurt, giving it its sour taste. These lactic acid bacteria can carry out either homolactic fermentation , where the end-product is mostly lactic acid, or heterolactic fermentation , where some lactate is further metabolized to ethanol and carbon dioxide [ 18 ] (via the ...
Dadiah is a traditional fermented milk of West Sumatra, Indonesia prepared with fresh, raw, and unheated buffalo milk. Fermented milk products or fermented dairy products, also known as cultured dairy foods, cultured dairy products, or cultured milk products, are dairy foods that have been made by fermenting milk with lactic acid bacteria such as Lactobacillus, Lactococcus, and Leuconostoc.
The Lactobacillaceae are a family of lactic acid bacteria. [3] It is the only family in the lactic acid bacteria which includes homofermentative and heterofermentative organisms; [4] in the Lactobacillaceae, the pathway used for hexose fermentation is a genus-specific trait.
These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB). Production of lactic acid has linked LAB with food fermentations, as acidification inhibits the growth of spoilage agents.
