NOV. Fructilactobacillus sanfranciscensis (san.fran.cis.cen’sis. N.L. masc. adj. sanfranciscensis , from San Francisco). Basonym: Lactobacillus sanfranciscensis (ex Kline and Sugihara 1971) Weiss and Schillinger 1984, 503 VL . The species wasdescribed as Lactobacillus sanfrancisco in 1971 [ 313 ] and re-named to Lactobacillus sanfranciscensis [ 314 ]. Isolates of F. sanfranciscensis described prior to 1978 were designated as Lactobacillus brevis subsp. lindneri [ 315 ] Virtually all isolates of the species originate from traditional sourdoughs that are used as leavening agent [ 114 ]; one isolate was obtained from agave mash [ 151 ]. The extremely small genome size of 1.2–1.3 Mbp, the restricted carbohydrate fermentation pattern, which for includes only maltose for some strains, and the narrow pH range of growth (pH 3.9–6.6) [ 316 , 317 ] document adaptation to a very narrow ecological niche. An insect origin of the species is suggested by culture-independent analysis of the microbiota of grain beetles [ 318 ]. The genome size of the type strain is 1.23 Mbp. The mol% G+C content of DNA is 34.7. Thetypestrainis L-12 T =ATCC 27651 T =DSM 20451 T =LMG 16002 T . Genome sequence accession number: AYYM00000000. 16S rRNA gene accession number: X76327 .
