  • a All listed strains are held in our collection. Strains marked with an asterisk have been reported to produce N-(3-oxooctanoyl)-l-homoserine lactone (4).

  • b TraR-QS, presence of a plasmid coding for a TraR-type quorum-sensing system; E, experimentally determined; S, determined by sequence analysis; ND, no data available.

  • c Determined by moderate-stringency Southern analysis using a blcC probe (SA+ and SA) and by Blastn, Blastp, and TBlastn analyses of genome sequences available in public databases (G+ and G).

  • d Growth on solid minimal medium with the indicated substrate as the sole carbon source was assessed visually and graded from +++++ (luxuriant growth) to − (no detectable growth).

  • e Two isolates of strain B6 with different plasmid complements (20).

  • f NA, not applicable.
