Lactiplantibacillus carotarum AMBF275T sp. nov. isolated from carrot juice fermentation.

ABSTRACT

A novel strain of the genus Lactiplantibacillus, named AMBF275T, was isolated from fermented carrot juice, a salted fermented beverage dominated by lactic acid bacteria. The results of phylogenetic analysis indicated that the 16S rRNA gene of AMBF275T is most similar to the 16S rRNA gene of Lactiplantibacillus garii FI11369T with a sequence similarity of 99.4 %. However, a genome-wide comparison using average nucleotide identity (ANI) revealed that AMBF275T and L. garii FI11369T have an ANI of only 82.35 %. ANI values between AMBF275T and other representative strains of species of the genus Lactiplantibacillus from the Genome Taxonomy Database (GTDB) were even lower than this 82.35 %, indicating that AMBF275T represents a distinct species. We thus propose the name Lactiplantibacillus carotarum sp. nov. for this novel species, with AMBF275T (=LMG 32885T, =CECT 30757T) as the type strain.
