Latilactobacillus fragifolii sp. nov., isolated from leaves of a strawberry plant (Fragaria x ananassa)

Thirteen Gram-positive, catalase-positive, rod-shaped single colonies were obtained after culturing a strawberry leaf on de Man–Rogosa–Sharpe agar. Based on 16S rRNA gene and rpoA gene sequence similarities, ranging between 99.0–100% and 96.5–100%, respectively, the 13 isolates were found to be closely related to each other. Two of the independent isolates, AMBP162(T) and AMBP252, were whole-genome sequenced, and showed to be undistinguishable with an average nucleotide identity (ANI) value of 100 %. Compared to the reference genomes for all species in the family Lactobacillaceae , the AMBP162(T) genome was most similar to the reference strain of Latilactobacillus curvatus with ANI of only 89.5 %, indicating they were a different species. Based on genotypic and phenotypic data, a novel Latilactobacillus species, Latilactobacillus fragifolii sp. nov., with the type strain AMBP162(T) (=LMG 32285(T)=CECT 30357(T)) is proposed.
