Biotechnological potential of the new strain of Pseudomonas fluorescens on the biosurfactant production utilizing petroleum as substrate
The chemical or biological surfactants are amphiphilic compounds which can reduce the superficial and interfacial tensions by accumulation on the interface of immiscible fluids, increase of solubility and biodegradability of hydrophobic compounds. Thus, the potential of biosurfactant production by P...

| Resumo: | The chemical or biological surfactants are amphiphilic compounds which can reduce the superficial and interfacial tensions by accumulation on the interface of immiscible fluids, increase of solubility and biodegradability of hydrophobic compounds. Thus, the potential of biosurfactant production by Pseudomonas fluorescens was investigated utilizing Luria Bertani medium culture, containing petroleum as substrate supplemented with 4 and 8%, maintained in orbital shaking at 150 rpm, and temperature of 37ºC, during 60 hours. The experimental results showed that P. fluorescens produced a biosurfactant which reduced the surface tension of 70 to 30,04 mN/m. These findings also confirmed its ability to remove and degrade petroleum, by means of production of surfactant agent, suggesting a possibility to apply in processes of hydrophobic contaminants, as petroleum. |
