Draft genome sequence of Citrobacter freundii strain ST2, a γ-proteobacterium that produces N-acylhomoserine lactones

Citrobacter freundii strain ST2, isolated from the algae bloom sample, possesses an N-acylhomoserine lactone (AHL) production activity that secretes short-chain AHL molecules. In this study, we sequenced the complete genome of C. freundii strain ST2 to understand the molecular regulation of the AHL system and to search for the AHL gene in this bacterium. The results show that the genome size is 4.89 Mb with a G + C content of 51.96%. 4626 function proteins were predicted and 3647 proteins were assigned to COG functional categories. A predicted AHL-coding gene LuxR was found at contig 4 and the length was 1541 bp. The strain temporary deposited at Shenzhen Public Platform of Screening & Application of Marine Microbial Resources (Shenzhen, China), and the genome sequence can be accessed at GenBank under the accession no. LJSQ00000000.
