Simultaneous syntheses of polyhydroxyalkanoates and rhamnolipids by Pseudomonas aeruginosa IFO3924 at various temperatures and from various fatty acids

▶ The optimum temperature for PHA synthesis is 30 °C. ▶ The optimum temperature for rhamnolipid (RL) synthesis is 28 °C. ▶ Codd-3-hydroxyalkanoates (3HAs) can be incorporated into RLs. ▶ PHAs and RLs produced from Ceven-fatty acids contain only Ceven-3HAs. ▶ PHAs and RLs produced from Codd-fatty acids contain Codd- and Ceven-3HAs.
