The effect of Nanoparticles on the Biosurfactant production by Pseudomonas aeruginosa for Use in the Oil Industry
Biosurfactants are surface tension reducing compounds produced by a wide range of microorganisms. These compounds are caused to facilitate the absorption insoluble substrate by microbial cells. The aim of this study was to investigate the effects of nanoparticles of Fe/SDS on the biosurfactant production by Pseudomonas aeruginosa in culture is molasses.
For this purpose were used different concentrations of nanoparticles 1, 500 and 1000 mg/L. As a result the concentration of 1mg /L of Fe/SDS nanoparticles has the best effect on the growth of bacteria and biosurfactant production. This concentration increased 23.21% cell growth and 20.73% biosurfactant production compared with control samples. By increasing the concentration of nanoparticles reduced growth rate and biosurfactant production was observed. This indicates that the nanoparticles having negative effects of higher concentrations.
The results showed that low concentrations of nanoparticles Fe/SDS has positive effects on bacterial biosurfactant production and therefore a good alternative to chemical surfactants for use in the petroleum industry.
