Lactic acid bacteria (LAB) already exists as part of the natural flora in most vegetables. Lettuce and cabbage were examined to determine the types of lactic acid bacteria that exist in the leaves. Different types of LAB will produce different types of silage fermentation, which is the fermentation of the leafy foliage. [19]
Species of Lactobacillus (and related genera) comprise many food fermenting lactic acid bacteria [39] [40] and are used as starter cultures in industry for controlled fermentation in the production of wine, yogurt, cheese, sauerkraut, pickles, beer, cider, kimchi, cocoa, kefir, and other fermented foods, as well as animal feeds and the bokashi ...
The lactic acid bacteria (LAB) are either rod-shaped (), or spherical (), and are characterized by an increased tolerance to acidity (low pH range).This aspect helps LAB to outcompete other bacteria in a natural fermentation, as they can withstand the increased acidity from organic acid production (e.g., lactic acid).
Lactic acid bacteria converts the unstable malic acid [41] that is naturally present in wine into the stable lactic acid. This malolactic fermentation gives the stability that is characteristic of high-quality wines that improve on storage. [42] Lactic acid bacteria are also used in food supplements as probiotics which help to restore the ...
During fermentation, the bean embryo is killed by heat and acidity generated by microbes, [10] [11] providing for an environment where flavor precursors can develop. When beans are removed from their pods, they are naturally exposed to these microbes from the environment, most importantly anaerobic yeasts, lactic acid bacteria, and acetic acid ...
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).

Lactococcus is a genus of lactic acid bacteria that were formerly included in the genus Streptococcus Group N1. [2] They are known as homofermenters meaning that they produce a single product, lactic acid in this case, as the major or only product of glucose fermentation.
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.
