Abstract

A Gram-positive bacterium originating from garden soil was taxonomically studied. Cells are non-motile, non-sporulating, irregular rods and cocci. The cell wall peptidoglycan contains L-ornithine as diagnostic diamino acid and an interpeptide bridge consisting of L-Orn<--L-Ala<--Gly<--D-Asp. The major menaquinone is MK-8(H4). 13-Methyl tetradecanoic acid and 14-methyl pentadecanoic acid are the predominant fatty acids. The polar lipids are phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol, three unknown glycolipids and three unknown phospholipids. Mycolic acids are absent. The DNA G+C composition is 70 mol%. The acyl type of the glycan chain of peptidoglycan is acetyl. Glucose is the dominating whole cell sugar; arabinose, rhamnose and xylose are present in traces. Results of 16S rDNA sequence comparisons revealed that strain HKI 0124T represents a novel lineage within the suborder Micrococcineae of the order Actinomycetales adjacent to the recently described genus Ornithinicoccus. On the basis of the clearly pronounced morphological, physiological, chemotaxonomic and phylogenetic differences between strain HKI 0124T and all members of the suborder Micrococcineae, it is proposed to assign strain HKI 0124T to a new genus and species, Ornithinimicrobium humiphilum gen. nov., sp. nov. The type and only strain is HKI 0124T (= DSM 12362T = CIP 106634T).
