Abstract :

From an environmental viewpoint, biosurfactants are more acceptable for the remediation process both at sea and land. Recently, the biosurfactant production has been growing up, because this substance has amphiphilic nature with high emulsifying and surface interaction. They are produced through metabolism of microorganisms and many applications are mentioned in industry (chemical, food, pharmaceutical etc.). The current study describes the biosurfactant production by Bacillus subtilis and Pseudomonas aeruginosa using agroindustrial and dairy wastes containing high levels of glucose. The biosurfactant production was evaluated according to the emulsification index (using oils), surface tension analysis. The biosurfactant produced using 10% of inoculums of Bacillus subtilis showed highest surface tension reduction and emulsification index than 5% and 7% inoculum. Pseudomonas aeruginosa showed biosurfactant production but the yield is very low. Hence, current research invented an alternative way to process industrial wastes and the use of natural surfactants, or biosurfactants, is among one of the most promising methods due the fact that such compounds are metabolic products of fungi, bacteria and certain strains of yeast.
