AbstractA strain NAPH6 of Pseudomonas aeruginosa, isolated from contaminated seawater taken from the fishing harbor of Sfax, Tunisia, was able to degrade almost completly the naphthalene (200 mg/l) and the aliphatic hydrocarbons of crude oil (1%, v/v), after 7 and 20 days of culture, respectively, at 30 g/l NaCl. Moreover, the isolated NAPH6 exhibited a notable potentiality to synthesize biological surfactants (BS-NAPH6) on inexpensive carbon sources. The Fourier Transform Infrared (FTIR) analysis suggested that BS-NAPH6 belonged to the glycolipid family. Besides, BS-NAPH6 displayed a high steadiness against a wide spectrum of pHs, temperatures and salinities. The treatment of human HEK293 cells by different concentrations of BS-NAPH6 displayed that this latter exhibited no cytotoxic effect at concentrations below 200 μg/mL. Furthermore, the application of BS-NAPH6 in hydrocarbons removal from polluted soil, demonstrated that it was more efficient than tested chemical surfactants. Interestingly, BS-NAPH6 highlighted a significant healing activity on the wound site in a rat model compared to a commercial cream. Due to their attractive biological properties, strain NAPH6 as well as its biosurfactant BS-NAPH6 are considered as promising candidates for various applications including environmental and biomedical ones.
