Abstract:Surfactin is one of the most effective biosurfactants available and has several interesting properties. However, the high cost and low yield associated with surfactin production have been major drawbacks preventing its wider industrial application. The use of intensive stirring and aeration, in order to increase surfactin synthesis, can cause excessive foaming, resulting in low levels of biosurfactant production inside the bioreactor. Therefore, the aim of this study was to evaluate the influence of the oxygen… Show more
