Abstract

Strain NCIMB 9991 is a Gram-positive, short rod-shaped, yellow-pigmented bacterium, with a high DNA G+C content, and was originally deposited in 1967 as sp. The bacterium is aerobic, non-motile, catalase-positive and oxidase-negative. Comparative 16S rRNA gene sequencing studies demonstrated that this strain was highly related genealogically to DSM 14012. Strain IAM 14817 (=NCIMB 9991) has the following characteristics: the predominant menaquinones are MK-9 and MK-10, the DNA G+C content is 68 mol%, the diamino acid in the cell wall is 2,4--diaminobutyric acid and the muramic acid in the peptidoglycan is of an acetyl type. The major fatty acid is 12-methyl tetradecanoic acid (anteiso-C), followed by 14-methyl hexadecanoic acid (anteiso-C), 14-methyl pentadecanoic acid (iso-C) and hexadecanoic acid (C). On the basis of morphological, physiological and chemotaxonomic characteristics, together with DNA–DNA hybridization and 16S rRNA gene sequence comparison, strain IAM 14817 represents a novel species within the genus , for which the name sp. nov. is proposed, with the type strain IAM 14817 (=NCIMB 9991=NBRC 15702).
