Aureispira maritima sp. nov., isolated from marine barnacle debris.

A novel gliding marine bacterium (strain 59SA(T)) was isolated from marine barnacle debris. A phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a distinct lineage within the genus Aureispira in the family 'Saprospiraceae'. The DNA G+C content of strain 59SA(T) was 38.7 mol%, the major respiratory quinone was MK-7 and the predominant cellular fatty acids were 20 : 4omega6c and 16 : 0. On the basis of the data from DNA-DNA hybridization, physiological and chemotaxonomic analyses and 16S rRNA gene sequence comparisons, strain 59SA(T) represents a novel species of the genus Aureispira, for which the name Aureispira maritima sp. nov. is proposed. The type strain is 59SA(T) (=IAM 15439(T)=TISTR 1726(T)).
