The species is generally viewed as being a cocci, forming long chains or pairs during its growth.
However, the morphology can change depending on what media the species is grown on, which can change them cremrois rod shaped or more simply, elongated forms. Crempris cells are Gram positive, which can aid in identification in human pathology. The bacteria is also a nonsporogenous and non-motile species. They are a facultative anaerobe and are a member of the lactic acid bacteria family, which includes Oenococcus oeniwhich are also closely related to the Lactobacillaceae also a LABwhich split off from the Streptococcaceae Marakova et al.
Under the correct micro anaerobic conditions, the L.
On sauerkraut specifically, the pH is lowered in the first phase by Klebsiella and Enterobacter species. This lowers the pH so that L. The third and final stage of the fermentation is then taken up by other LABs related to L. This shows the importance that L.
This feature is also utilized in the meat and dairy industry, as L. This is further evidence that L. The genome is circular and does contain a variety of plasmids, which aid in citrate metabolism, and bacterioicin development.
The lactic acid bacteria genomes generally encode for carbon and nitrogen acquisition within their environments.
These genes seem to have spawned from the process of horizontal gene transfer as a coevolutionary method from their habitats Marakova et al. This results in the break down of glucose and other sugars into D-lactate, ethanol, and CO2 Demoss et al ; Garvie ; Gottschalk It will also convert citrate into diacetyl and acetoin, and will convert sucrose into destrans and levan.
Dextrans are used for a variety of different commercial products, some of which include cosmetics, blood plasma extenders, and heparin substitutes Leathers et al ; Sutherland ; Alsop ; Kim and Day A variety of polysaccharides mesentedoides also produced from the metabolic pathways which creates a gel that renders the product unusable, and therefore necessary precautions have to be taken to avoid an accumulation leuconistoc unwanted metabolite Tallgren et al.
There are many pathways L. Some end products of note are mannitol, acetate, and lactate, but other pathways exist.

The schematic shows a brief process of the L. G1P, glucosephosphate; G6P, glucosephosphate; F6P, fructosephosphate; GAP, glyceraldehydephosphate; acetyl-P, acetylphosphate; acetyl-CoA, acetyl coenzyme A; 1, sucrose phosphorylase; 2, dextransucrase; 3,phosphoglucomutase PGM ; 4, glucokinase; 5, fructokinase; 6, mannitol dehydrogenase; 7, pyruvate dehydrogenase.
However, there are certain documented instances where L. The most surprising of which was a case study where a woman, who was originally thought to have brain tumors, actually had two purulent lesions in her brain that were later successfully identified as an L. Another case is shown where Leuconostoc species are found in cancer patients, and within patients who are critically ill, immunocompromised, or nonsocomial Cuervo et al.
At this time, L. Page authored by Chandler F. Divan, student of Prof. Jay Lennon at Indiana University- Bloomington.
