Fructilactobacillus frigidiflavus sp. nov., a pigmented species, and Levilactobacillus lettrarii sp. nov., a propionate-producing species isolated from sourdough.
The sourdough isolates FUA3702, FUA3912 and FUA3913T, as well as FUA3695T and FUA3914, could not be identified to known species of the Lactobacillaceae. The 16S rRNA gene sequences of FUA3702 and FUA3913, FUA3695 and FUA3914 were>99% identical to Fructilactobacillus sanfranciscensis and Levilactobacillus lanxiensis, respectively. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values of strain FUA3913T when compared to Fl. sanfranciscensis were 83.67 and 26.60%, respectively. In addition, strains FUA3702, FUA3912 and FUA3913T produce different levels of a yellow C30 carotenoid, but pigmentation has not been described in Fl. sanfranciscensis. The ANI and dDDH values of FUA3695T and FUA3914 when compared to Lv. langxiensis were 95.22 and 61.20%, respectively. In addition, FUA3695 and FUA3914 convert lactate to 1,2-propanediol and further to propionate. The conversion of lactate to propionate by a single strain has not been documented for any of the species in the Lactobacillaceae. Based on the genomic and physiological characteristics, we proposed the novel species Fructilactobacillus frigidiflavus sp. nov. FUA3913T (=DSM 118650T=LMG 33758T) and Levilactobacillus lettrarii sp. nov. FUA3695T (=DSM 118651T=LMG 33759T).
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
