Complete genome sequence of Rhodococcus erythropolis BG43 (DSM 46869), a degrader of Pseudomonas aeruginosa quorum sensing signal molecules

Abstract Rhodococcus erythropolis BG43 was isolated from soil and characterized as a degrader of the quorum sensing signal molecules 2-heptyl-3-hydroxy-4(1 H )-quinolone (the Pseudomonas quinolone signal, PQS) and 2-heptyl-4(1 H )-quinolone, produced by Pseudomonas aeruginosa . The complete genome of R. erythropolis BG43 consists of a circular chromosome and three plasmids, one of them circular and two linear ones. In total, 6158 protein-coding regions were identified. With this genome sequence, the genetic basis of its quorum-quenching ability and possible biotechnological applications can be explored further.
