On the basis of the above tests (Table 2), the strain PS1 was tentatively identified as Pseudomonas. The partial gene sequencing of 16S rRNA of the strain PS1 was performed commercially at DNA Sequencing Service, Macrogen Inc., Seoul, South Korea. Subsequently, nucleotide sequence data (Gen-Bank accession number FJ705886) was deposited in the Gen-Bank sequence database. The online program BLAST (Basic Local Alignment Search Tool) was used to find out the related sequences with known taxonomic information in the databank at NCBI website (http:// www.ncbi.nlm.nih.gov/BLAST) to accurately identify the strain PS1.
