NOV. Limosilactobacillus reuteri (reu ′ te.ri. N.L. gen. n. reuteri , of Reuter; named for G. Reuter, a German bacteriologist). Basonym: Lactobacillus reuteri Kandler et al . 1982 , 266 VL Prior to 1980, strains of the species were classified as L. fermentum Biotype II [ 268 ]. The species has been studied as model species to determine host-adaptation of intestinal lactobacilli, and co-adaptation of Limosilactobacillus and Lactobacillus species (e.g. L. taiwanensis ) that coexist in biofilms in intestinal ecosystems and preferentially different substrates [ 55 , 56 , 269 ]. L. reuteri is divided in host-adapted lineages that are equivalent to the taxonomic rank of subspecies [ 269 , 270 ] and differ in their ability to form biofilms in the mouse forestomach [ 271 ]. Few strains of L. reuteri produce the antimicrobial compound reutericyclin with a polyketide synthase, which is a unique ability among lactobacilli [ 272 ]. The genome size of the type strain is 1.94 Mbp. The mol% G+C content of DNA is 38.6. Isolated as dominant members of the intestinal microbiota of rodents, birds, swine, and in other intestinal ecosystems; also occurs in cereal fermentations, particularly type II sourdoughs [ 58 ]. Food isolates are of intestinal origin [ 273 ]. Thetype strain of the species is F 275 T = ATCC 23272 T =DSM 20016 T = JCM 1112 T =LMG 9213 T = LMG 13557 T .
