Biosurfactant produced by L. delbrueckii
using peanut oil cake in this study showed its potential to be used in bioremediation process. Unlike medicinal applications, environmental application of biosurfactants needs comparatively less purity and high activity.
In this study peanut oil cake was used as the carbon source for biosurfactant production. Even though the biosurfactant was not purified to its purest form and structurally not well characterized but the results on emulsification and biodegradation experiments revealed the potential use of this biosurfactant in bioremediation of hydrocarbon pollution. Which emphasize that for environmental applications the biosurfactants need not be pure and could be synthesized from a mixed cheaper carbon source like peanut oil
cake used in this study. All these approaches will make the bioremediation process an economically and environmentally viable mitigation technology.
