Abstract

The taxonomic position of a lemon-yellow-pigmented actinobacterium, strain JF-6T isolated from Aurelia aurita, the moon Jelly fish, collected from Bay of Bengal coast, Kanyakumari, India, was determined using a polyphasic approach. The strain had phenotypic and chemotaxonomic properties that were consistent with its classification in the genus Microbacterium. Alignment of the 16S rRNA gene sequence of strain JF-6T with sequences from Microbacterium arthrosphaerae CC-VM-YT, Microbacterium yannicii G72T, Microbacterium trichothecenolyticum IFO 15077T, Microbacterium flavescens DSM 20643T, Microbacterium insulae DS-66T, Microbacterium resistens DMMZ 1710T and Microbacterium thalassium IFO 16060T revealed similarities of 98.95, 98.76, 98.43, 98.41, 98.41, 98.26 and 98.22% respectively. However, the level of DNA-DNA relatedness with its close phylogenetic neighbours confirmed that it represents a novel species within the genus. The major polar lipids are phosphatidylglycerol (PG), diphosphatidylglycerol (DPG) and an unknown glycolipid. The major menaquinones detected for the strain JF-6T are MK-13 and MK-12. The diamino acid in cell wall peptidoglycan was ornithine and the peptidoglycan type B2 (Glu/Hyg-Gly-D-Orn). The DNA G+C content is 69.4 mol%. Based on these differences, strain JF-6T (= MTCC 11843T= JCM 30060T= KCTC 39828T) should be classified as the type strain of a novel species of Microbacterium, for which the name Microbacterium aureliae sp. nov. is proposed.
