Janibacter corallicola sp. nov., isolated from coral in Palau.

A novel Janibacter species is described on the basis of phenotypic, chemotaxonomic and genotypic data. Two bacterial strains were isolated in Palau, which were both Gram-positive, catalase-positive bacteria with meso-diaminopimelic acid as the diagnostic diamino acid of the peptidoglycan. The major menaquinone was MK-8(H(4)). Mycolic acids were not detected. The G+C content of the DNA was 70-71 mol%. Comparative 16S rDNA studies of the two isolated strains revealed that they both belonged to the genus Janibacter. DNA-DNA relatedness data revealed that 04PA2-Co5-61(T) and 02PA-Ca-009 belong to the same species, a new species of the genus Janibacter. From these results, Janibacter corallicola sp. nov. is proposed, with the type strain 04PA2-Co5-61(T) (=MBIC 08265(T), DSM 18906(T)).
