Abstract

A polyphasic taxonomic study of the bacterial flora isolated from traditional French wheat sourdough, using phenotypic characterization and phylogenetic as well as genetic methods, revealed a consistent group of isolates that could not be assigned to any recognized species. These results were confirmed by randomly amplified polymorphic DNA and amplified fragment length polymorphism fingerprinting analyses. Cells were Gram-positive, homofermentative rods. Comparative 16S rRNA gene sequence analysis of the representative strain LP33 indicated that these strains belong to the genus and that they formed a branch distinct from their closest relatives , , and . DNA–DNA reassociation experiments with the three phylogenetically closest species confirmed that LP33 (=DSM 16982=CIP 108546=TMW 1.1265) represents the type strain of a novel species, for which the name sp. nov. is proposed.
