CORYNEBACTERIUM-KROPPENSTEDTII SP. NOV., A NOVEL CORYNEBACTERIUM THATDOES NOT CONTAIN MYCOLIC ACIDS

A strain of a hitherto undescribed coryneform bacterium from human cli nical material was characterized by phenotypic and molecular taxonomic methods. Comparative 16S rRNA gene sequence analysis demonstrated the strain represents a novel and deep lineage within the genus Corynebac terium sensu stricto. Chemical analyses revealed the unidentified stra in was unusual in that it lacked mycolic acids. Based on the phylogene tic and phenotypic distinctiveness of the unknown isolate, it is propo sed that the bacterium be classified as a new Corynebacterium species, for which the name Corynebacterium kroppenstedtii sp, nov, is propose d. The type strain is CCUG 35717(T).
