| Abstract |
The zha-chili isolate HBUAS62285T is a facultative anaerobic strain. This bacterium was gram-positive, but it could not generate catalase, was not motile, did not form spores, had no flagella, and produced gamma-aminobutyric acid (GABA). Comparing of HBUAS62285T with its related type strains Levilactobacillus suantsaiihabitans BCRC 81129T, Levilactobacillus angrenensis M1530-1T, Levilactobacillus cerevisiae DSM 100836T, Levilactobacillus wangkuiensis 6-5(1)T, Levilactobacillus lanxiensis 13B17T, and Levilactobacillus mulengensis 112-3T showed that the similarity of 16S rRNA gene sequence was less than 99.13%. Strain HBUAS62285T has a G+C content of 50.57 mol%, an ANI value of less than 86.61%, an AAI value of less than 92.9%, and a dDDH value of less than 32.9% when compared to the aforementioned closely related strains. In the end, the most major fatty acids in cells were determined to be C16:0, C18:1 ω9c, C19:1 cyclo ω9,10c, and summed feature 10. Overall, the results of the phenotypic, genomic, chemotaxonomic, and phylogenetic studies indicate that strains HBUAS62285T and CD0817 constitute a new species within the genus Levilactobacillus, and the name Levilactobacillus yiduensis sp. nov. is proposed. The type strain is HBUAS62285T (= JCM 35804T = GDMCC 1.3507T).
