Limosilactobacillus Explained

Limosilactobacillus is a thermophilic and heterofermentative genus of lactic acid bacteria created in 2020 by splitting from Lactobacillus.[1] The name is derived from the Latin Latin: limosus "slimy", referring to the property of most strains in the genus to produce exopolysaccharides from sucrose.[2] The genus currently includes 31 species or subspecies, most of these were isolated from the intestinal tract of humans or animals.[3] Limosilactobacillus reuteri has been used as a model organism to evaluate the host-adaptation of lactobacilli to the human and animal intestine [4] [5] and for the recruitment of intestinal lactobacilli for food fermentations.[6] [7]

Limosilactobacilli are heterofermentative and produce lactate, CO2, and acetate or ethanol from glucose; several limosilactobacilli, particularly strains of Lm. reuteri convert glycerol or 1,2-propanediol to 1,3 propanediol or propanol, respectively.[8] Most strains do not grow in presence of oxygen, or in de Man, Rogosa Sharpe (MRS) medium, the standard medium for cultivation of lactobacilli. Addition of maltose, cysteine and fructose to MRS is usually sufficient for cultivation of limosilactobacilli.

Species

The genus Limosilactobacillus comprises the following species:[9]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature[9] and the phylogeny is based on whole-genome sequences.[1]
