A Gram-positive, coccus-shaped, lactic acid bacterium, strain NGRI 0510QT, was isolated from ryegrass silage produced in Okinawa Prefecture, Japan. The cell is non-spore-forming, non-motile, and occurs in pairs or tetrads. The strain is homofermentative and produces D- and L-lactic acid from glucose. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain NGRI 0510QT belongs to the genus Pediococcus and clusters within the Pediococcus acidilactici and Pediococcus pentosaceus group, with 98.2 and 96.9% sequence identity, respectively. DNA-DNA relatedness between strain NGRI 0510QT and P. acidilactici JCM 8797T and P. pentosaceus JCM 5890T was 19.3 and 17.3 %, respectively. Based on its phenotypic characteristics, phylogenetic relationship and DNA-DNA relatedness, NGRI 0510QT (=JCM 15055T=DSM 19927T) represents the type strain of a novel species, for which the name Pediococcus lolii sp. nov. is proposed.
