  2. Lactic acid fermentation - Wikipedia

    en.wikipedia.org/wiki/Lactic_acid_fermentation

    Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.

  3. Fermentation theory - Wikipedia

    en.wikipedia.org/wiki/Fermentation_theory

    One of the chemical processes that Pasteur studied was the fermentation of sugar into lactic acid, as occurs in the souring of milk. In an 1857 experiment, Pasteur was able to isolate microorganisms present in lactic acid ferment after the chemical process had taken place. [9] Pasteur then cultivated the microorganisms in a culture with his ...

  4. Fermentation - Wikipedia

    en.wikipedia.org/wiki/Fermentation

    The high concentration of lactic acid (the final product of fermentation) drives the equilibrium backwards (Le Chatelier's principle), decreasing the rate at which fermentation can occur and slowing down growth. Ethanol, into which lactic acid can be easily converted, is volatile and will readily escape, allowing the reaction to proceed easily.

  5. List of fermented milk products - Wikipedia

    en.wikipedia.org/wiki/List_of_fermented_milk...

    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.

  6. Fermentation in food processing - Wikipedia

    en.wikipedia.org/wiki/Fermentation_in_food...

    In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy.

  7. Biopreservation - Wikipedia

    en.wikipedia.org/wiki/Biopreservation

    In addition to lactic acid bacteria, yeasts also have been reported to have a biopreservation effect due to their antagonistic activities relying on the competition for nutrients, production and tolerance of high concentrations of ethanol, as well as the synthesis of a large class of antimicrobial compounds exhibiting large spectrum of activity against food spoilage microorganisms, but also ...

  8. Lactobacillus delbrueckii subsp. bulgaricus - Wikipedia

    en.wikipedia.org/wiki/Lactobacillus_delbrueckii...

    The efficiency of lactic acid bacteria cryopreservation is not consistent and may lead to cell death. Lactobacillus delbrueckii subsp. bulgaricus has adapted to defend against cold stress. The way most cells react to the cold is by changing the fluidity of the cellular membrane, but this particular bacterium has acquired different tactics to ...

  9. Lactobacillus acidophilus - Wikipedia

    en.wikipedia.org/wiki/Lactobacillus_acidophilus

    Pathway by which glucose is converted to lactic acid as a means of energy production. L. acidophilus is a homofermentative anaerobic microorganism, meaning it only produces lactic acid as an end product of fermentation; and that it can only ferment hexoses (not pentoses) by way of the EMP pathway (glycolysis).
