Microbial biotransformations of HHQ/PQS. (A) Oxidation of HHQ by P. aeruginosa (PqsH) (Gallagher et al., 2002), Rhodococcus sp. BG43 and Streptomyces sp. RKBH-B178. (B) Glucuronidation of PQS by Streptomyces sp. RKBH-B178. (C) Degradation of PQS to anthranilic acid (7) by Rhodococcus sp. BG43 (Muller et al., 2014). (D) Degradation of PQS to N-octanoylanthranilic acid (8) by Arthrobacter nitroguajacolicus strain Rü61a (Hod) (Pustelny et al., 2009). (E) Oxidation of PQS to HHQD (9) by Achromobacter xylosoxidans Q19 (Soh et al., 2015).
