| Abstract |
Strain CQ16Z1T was isolated from jamiecosley, a traditional Chinese pickle. The isolate was Gram-positive, non-motile, non-spore-forming, facultatively anaerobic, catalase-negative, and long rod-shaped. The optimal temperature for growth was 37 °C and the DNA G + C content was 39.1 mol%. The results of 16S rRNA and rpoA gene sequencing, DNA-DNA hybridization, and peptidoglycan type analyses indicated that strain CQ16Z1T belongs to the recognized species Lactobacillus futsaii. However, the analysis results of pheS gene sequencing, amplified fragment length polymorphism, phenotypic profiles, cellular fatty acid, cell-wall monosaccharide determination, and cell morphology revealed that the novel strain was obviously different from the type strain L. futsaii JCM17355T, and had genetic relationship with Weissella cibaria to a certain degree, suggesting that the novel strain represents a novel subspecies of L. futsaii, for which the following names are proposed: L. futsaii subsp. futsaii subsp. nov. (type strain YM0097T = JCM 17355T = BCRC 80278T) and L. futsaii subsp. chongqingii subsp.nov., with the type strain CQ16Z1T (= CCTCC AB2017187T = KCTC 21089T).
