Abstract

Strain FIRDI 006, isolated from silage cattle feed, was characterized by using phenotypic and molecular taxonomic methods. The strain was a homofermentative lactic acid bacterium; the cells stained Gram-positive and were catalase-negative, non-motile, facultatively anaerobic rods. 16S rRNA gene sequence analysis revealed that the strain belongs phylogenetically to the genus and can be placed within the group. and were the most closely related species, with 16S rRNA gene sequence similarities of 99.53 and 99.46 % to the respective type strains. Low gene sequence similarities (<90 %) and low DNA–DNA reassociation values (<45 %) were obtained between the strain and the phylogenetically closest neighbours. Based on phenotypic and genetic evidence, the strain is considered to represent a novel species, for which the name sp. nov. is proposed. The type strain is FIRDI 006 (=BCRC 17755 =DSM 21401).
