Agrococcus casei sp nov., isolated from the surfaces of smear-ripened cheeses

Seven Gram-positive, coryneform bacteria with virtually identical whole-organism protein patterns were isolated from the surface of smear-ripened cheeses. Representatives of these strains were the subject of a polyphasic study designed to establish their taxonomic status. The organisms formed a distinct branch in the Microbacteriaceae 16S rRNA gene tree and were most closely related to members of the genus Agrococcus, sharing sequence similarities of 95.4-98.7%. The chemotaxonomic profiles of the strains were consistent with their classification in the genus Agrococcus. The combined genotypic and phenotypic data show that the isolates should be classified in the genus Agrococcus as representatives of a novel species. The name Agrococcus casei sp. nov. is proposed for this taxon. Isolate R-17892t2(T) (= DSM 18061(T) = LMG 22410(T)) is the type strain of Agrococcus casei sp. nov.
