The lactic acid bacteria (LAB) are either rod-shaped ( bacilli ), or spherical ( cocci ), 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 ).
Natural occurrence and industrial production Lemons, oranges, limes, and other citrus fruits contain high concentrations of citric acid. Citric acid occurs in a variety of fruits and vegetables, most notably citrus fruits.Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in the juices).

Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is an acidic, colourless liquid and organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. ...
CRISPR (/ˈkrɪspər/) (an acronym for clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea.[2] These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and ...
Bacteria (/bækˈtɪəriə/ ⓘ; sg.: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats ...
Adrenochrome is a chemical compound produced by the oxidation of adrenaline (epinephrine). It was the subject of limited research from the 1950s through to the 1970s as a potential cause of schizophrenia. While it has no current medical application, the semicarbazide derivative, carbazochrome, is a hemostatic medication. Despite this compound ...
After the Deluge is an oil painting by English artist George Frederic Watts. Completed in 1891, it shows a scene from the story of Noah's Flood, in which Noah opens the window of his Ark to see that after 40 days the rain has stopped. The Symbolist painting is a stylised seascape, dominated by a bright sunburst breaking through clouds.
