Pediococcus is a genus of gram-positive lactic acid bacteria, placed within the family of Lactobacillaceae. They usually occur in pairs or tetrads, and divide along two planes of symmetry, as do the other lactic acid cocci genera Aerococcus and Tetragenococcus. They are purely homofermentative.
Leuconostoc is a genus of gram-positive bacteria, placed within the family of Lactobacillaceae. They are generally ovoid cocci often forming chains. Leuconostoc spp. are intrinsically resistant to vancomycin and are catalase-negative. All species within this genus are heterofermentative and are able to produce dextran from sucrose. They are generally slime-forming.
The Lactobacillaceae are a family of lactic acid bacteria. It is the only family in the lactic acid bacteria which includes homofermentative and heterofermentative organisms; in the Lactobacillaceae, the pathway used for hexose fermentation is a genus-specific trait. Lactobacillaceae include the homofermentative lactobacilli Lactobacillus, Holzapfelia, Amylolactobacillus, Bombilactobacillus, Companilactobacillus, Lapidilactobacillus, Agrilactobacillus, Schleiferilactobacillus, Loigolactobacillus, Lacticaseibacillus, Latilactobacillus, Dellaglioa, Liquorilactobacillus, Ligilactobacillus, and Lactiplantibacillus; the heterofermentative lactobacilli Furfurilactobacillus, Paucilactobacillus, Limosilactobacillus, Fructilactobacillus, Acetilactobacillus, Apilactobacillus, Levilactobacillus, Secundilactobacillus, and Lentilactobacillus, which were previously classified in the genus Lactobacillus; and the heterofermentative genera Convivina, Fructobacillus, Leuconostoc, Oenococcus, and Weissella which were previously classified in the Leuconostocaceae.
Weissella is a genus of gram-positive bacteria placed within the family Lactobacillaceae, formerly considered species of the Leuconostoc paramesenteroides group. The morphology of Weissella species varies from spherical or lenticular cells to irregular rods. Several strains of Weissella cibaria and Weissella confusa have shown probiotic potential. In particular, the cell-free culture supernatant of Weissella confusa shows a number of beneficial characteristics, such as antibacterial potential and anti-inflammatory efficiency. However, several strains of W. confusa are opportunistic bacteria. A number of studies have been done on the safety of the bacterial species, indicating their probiotic potential. The Senate Commission on Food Safety has validated the use of W. confusa in food.
Weissella oryzae is a Gram-positive bacterium from the genus of Weissella which has been isolated from fermented Japanese rice from Tochigi Prefecture in Japan.
Limosilactobacillus is a thermophilic and heterofermentative genus of lactic acid bacteria created in 2020 by splitting from Lactobacillus. The name is derived from the Latin limosus "slimy", referring to the property of most strains in the genus to produce exopolysaccharides from sucrose. The genus currently includes 31 species or subspecies, most of these were isolated from the intestinal tract of humans or animals. Limosilactobacillus reuteri has been used as a model organism to evaluate the host-adaptation of lactobacilli to the human and animal intestine and for the recruitment of intestinal lactobacilli for food fermentations.
Apilactobacillus is a genus of bacteria from the family of Lactobacillaceae.
Companilactobacillus is a genus of lactic acid bacteria.
Fructilactobacillus is a genus of lactic acid bacteria.
Furfurilactobacillus is a genus of lactic acid bacteria.
Lacticaseibacillus is a genus of lactic acid bacteria.
Lactiplantibacillus is a genus of lactic acid bacteria.
Lapidilactobacillus is a genus of lactic acid bacteria.
Latilactobacillus is a genus of lactic acid bacteria.
Lentilactobacillus is a genus of lactic acid bacteria.
Levilactobacillus is a genus of lactic acid bacteria.
Ligilactobacillus is a genus of lactic acid bacteria associated with vertebrate hosts, formed through the 2020 division of the Lactobacillus genus. Most of these homofermentative species are motile and express urease to survive gastric acids, making them popular choices for probiotics. The G/C content of this genus varies between 32.5-43.3%.
Liquorilactobacillus is a genus of lactic acid bacteria.
Paucilactobacillus is a genus of lactic acid bacteria.
Schleiferilactobacillus is a genus of lactic acid bacteria.
