<i>Fructilactobacillus frigidiflavus</i> sp. nov., a pigmented species, and <i>Levilactobacillus lettrarii</i> sp. nov., a propionate-producing species isolated from sourdough.

ABSTRACT: The sourdough isolates FUA3702, FUA3912 and FUA3913^T, as well as FUA3695^T 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 FUA3913^T when compared to Fl. sanfranciscensis were 83.67 and 26.60%, respectively. In addition, strains FUA3702, FUA3912 and FUA3913^T produce different levels of a yellow C30 carotenoid, but pigmentation has not been described in Fl. sanfranciscensis. The ANI and dDDH values of FUA3695^T
