FermentationFermentation is a metabolic process that produces chemical changes in organic substances through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. In food production, it may more broadly refer to any process in which the activity of microorganisms brings about a desirable change to a foodstuff or beverage. The science of fermentation is known as zymology.
Lactic acid fermentationLactic 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. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells. If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of oxygen.
Paris CommuneThe Paris Commune (Commune de Paris, kɔ.myn də pa.ʁi) was a French revolutionary government that seized power in Paris from 18 March to 28 May 1871. During the Franco-Prussian War of 1870–71, the French National Guard had defended Paris, and working-class radicalism grew among its soldiers. Following the establishment of the Third Republic in September 1870 (under French chief executive Adolphe Thiers from February 1871) and the complete defeat of the French Army by the Germans by March 1871, soldiers of the National Guard seized control of the city on March 18.
GenevaGeneva (dʒəˈniːvə ; Genève ʒənɛv) is the second-most populous city in Switzerland (after Zürich) and the most populous city of Romandy, the French-speaking part of Switzerland. Situated in the south west of the country, where the Rhône exits Lake Geneva, it is the capital of the Republic and Canton of Geneva, and a center for international diplomacy. The city of Geneva (ville de Genève) had a population of 203,951 in 2020 (Jan. estimate) within its small municipal territory of , but the Canton of Geneva (the city and its closest Swiss suburbs and exurbs) had a population of 504,128 (Jan.
Communes of FranceThe commune (kɔmyn) is a level of administrative division in the French Republic. French communes are analogous to civil townships and incorporated municipalities in the United States and Canada, Gemeinden in Germany, comuni in Italy, or municipios in Spain. The UK equivalent are civil parishes. Communes are based on historical geographic communities or villages and are vested with significant powers to manage the populations and land of the geographic area covered. The communes are the fourth-level administrative divisions of France.
