title: Lactobacillus delbrueckii subsp. jakobsenii subsp. nov., isolated from dolo wort, an alcoholic fermented beverage in Burkina Faso.
abstract: Lactobacillus delbrueckii is divided into five subspecies based on phenotypic and genotypic differences. A novel isolate, designated ZN7a-9(T), was isolated from malted sorghum wort used for making an alcoholic beverage (dolo) in Burkina Faso. The results of 16S rRNA gene sequencing, DNA-DNA hybridization and peptidoglycan cell-wall structure type analyses indicated that it belongs to the species L. delbrueckii. The genome sequence of isolate ZN7a-9(T) was determined by Illumina-based sequencing. Multilocus sequence typing (MLST) and split-decomposition analyses were performed on seven concatenated housekeeping genes obtained from the genome sequence of strain ZN7a-9(T) together with 41 additional L. delbrueckii strains. The results of the MLST and split-decomposition analyses could not establish the exact subspecies of L. delbrueckii represented by strain ZN7a-9(T) as it clustered with L. delbrueckii strains unassigned to any of the recognized subspecies of L. delbrueckii. Strain ZN7a-9(T) additionally differed from the recognized type strains of the subspecies of L. delbrueckii with respect to its carbohydrate fermentation profile. In conclusion, the cumulative results indicate that strain ZN7a-9(T) represents a novel subspecies of L. delbrueckii closely related to Lactobacillus delbrueckii subsp. lactis and Lactobacillus delbrueckii subsp. delbrueckii for which the name Lactobacillus delbrueckii subsp. jakobsenii subsp. nov. is proposed. The type strain is ZN7a-9(T) = DSM 26046(T) = LMG 27067(T).
