Genomic DNA was extracted with a genomic DNA extraction kit(Tiangen, China) according to the manufacturer’s instructions.
The16S rRNA gene was amplified according to a reported method [13].
Evolutionary distance was estimated using the maximum compos-ite likelihood (MCL) method, and the phylogenetic tree was inferredusing the neighbour-joining algorithm in the MEGA software ver-sion 5 [14].
The 16S rDNA sequence of Pseudoalteromonas sp. DL-6was deposited in GenBank under accession number KF208362.2.4
