Lactobacillus hulanensis sp. nov., isolated from suancai, a traditional Chinese pickle

A Gram-stain-positive bacterial strain, ZW163 T , isolated from suancai, a traditional pickle of Heilongjiang province in China, was characterized by a polyphasic approach, including phenotypic characterization, sequence analyses of the 16S rRNA gene and two housekeeping genes (pheS and rpoA), whole genome sequencing and cellular fatty acid composition. Strain ZW163 T was phylogenetically related to Lactobacillus sharpeae, Lactobacillus songhuajiangensis, Lactobacillus pantheris and Lactobacillus thailandensis, having 93.8-98.7 % 16S rRNA gene sequence similarities, 76.5-87.1 % pheS gene sequence similarities and 74.3-95.7 % rpoA gene sequence similarities to the type strains of L. sharpeae, L. songhuajiangensis, L. pantheris and L. thailandensis, respectively. Average nucleotide identity and in silico DNA-DNA hybridization values between strain ZW163 T and the type strains of L. sharpeae, L. songhuajiangensis, L. pantheris and L. thailandensis were less than 77.7 % and 23.6 % respectively. Based upon the data obtained in the present study, a novel species, Lactobacillushulanensis sp. nov., is proposed and the type strain is ZW163 T (=NCIMB 15193 T =CCM 8926 T =CCTCC AB 2019015 T ).
