title: Corynebacterium efficiens sp. nov., a glutamic-acid-producing species from soil and vegetables.
abstract: Three glutamic-acid-producing coryneform strains were isolated from soil and vegetable samples. Chemotaxonomic investigations indicated that these strains belonged to the genus Corynebacterium. Phylogenetic studies, based on 16S rDNA analysis, demonstrated that the three strains formed a distinct cluster within the genus Corynebacterium and that their nearest relatives were Corynebacterium glutamicum and Corynebacterium callunae, also known as glutamic-acid-producing species. The data from 16S rDNA sequence and DNA-DNA relatedness studies clearly indicated that the three isolates represented a new species within the genus Corynebacterium. All of the isolates could grow at 45 degrees C and produced acid from dextrin; these were the most significant characteristics differentiating the three isolates from their neighbours. On the basis of the data presented here, it is proposed that the three glutamic-acid-producing isolates together be classified as Corynebacterium efficiens sp. nov., the type strain of which is YS-314T (= AJ 12310T = JCM 11189T = DSM 44549T).
