Lactobacillus garii sp. nov., isolated from a fermented cassava product.

A novel Gram-positive, catalase negative, rod-shaped strain, FI11369T, was isolated from gari, a traditional West African fermented food derived from cassava. Based on 16S rRNA gene sequence similarity, the closest type strains were Lactobacillus xiangfangensis LMG 26013T (99.4 % similarity), Lactobacillus plajomi NBRC 107333T (99.1 %), Lactobacillus paraplantarum DSM 10667T (99.1 %), Lactobacillus pentosus DSM 20314T (99.0 %), Lactobacillus plantarum subsp. plantarum ATCC 14917T (99.0 %), Lactobacillus modestisalitolerans NBRC 107235T (98.9 %), Lactobacillus plantarum subsp. argentoratensis DSM 16365T (98.9 %) and Lactobacillus daowaiensis NCIMB 15183T (98.8 %). The genome of strain FI11369T was sequenced and the average nucleotide identity (ANI) was compared with its closest relatives. ANI analysis showed that the closest relative, L. xiangfangensis DSM 27103T, had only a 82.4 % similarity. The main fatty acids of FI11369T were saturated C16 : 0 (18.2 %), unsaturated C18 : 1  ω9c (43.8 %) and cyclopropane C19 : 0 cyclo (ω10c and/or ω6; 22.5 %). Based on the genotypic and phenotypic data obtained in this study, a novel Lactobacillus species, Lactobacillus garii sp. nov., with the type strain FI11369T (=NCIMB 15148=DSM 108249), is proposed.
