Brevundimonas mediterranea D151-2-6 is a marine bacterium that has been isolated from 6582-m hadal sediment of the Pacific Ocean. Here, we present the complete genome sequence of B. mediterranea D151-2-6. The genome of strain D151-2-6 is 3,383,373 base pairs in size. It contains one circular chromosome with an average G + C content of 67.41%, 53 tRNAs, and 3270 protein-coding genes. Genomic analysis of strain D151-2-6 revealed that its genome is more highly enriched in genes that encode proteins involved in signal transduction and transcription than any of the other available completely sequenced Brevundimonas genomes. Some of these genes might improve ecological fitness in the hadal extreme environment. Genomic information on B. mediterranea D151-2-6 provides insights into the adaptation strategies and physiological features of Brevundimonas spp. in the hadal environment.
