Lactic acid bacteria

Group of bacteria (MSB) that are one of the few that can survive in an acidic solution. They do not need oxygen. They are therefore anaerobic bacteria for which oxygen is poison, so to speak. They are found in milk and are involved in the production of cheese, yoghurt or sour milk. Their growth or multiplication in grapes occurs only to a small extent. In alcoholic fermentation they are almost inactive and can hardly multiply. With regard to carbohydrate metabolism, a distinction is made between homofermentative and heterofermentative MSB. Homofermentative MSB such as Lactobacillus plantarum only form lactic acid.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
