The nutritionally versatile
Pseudomonas putida
has showed to grow in olive oil waste water called "alpechín", which is toxic for many other microorganisms. The transformation with the plasmid pSK2665, harboring
Alcaligenes eutrophus
genes needed for synthesis of poly (3-hidroxybutyric acid), allow
Pseudomonas
strain to grow in high concentration of the wastewaters "alpechín" accumulating biodegradable thermoplastic.
