Evaluation of the purification process in rhamnolipid biosurfactant for application in microbial-enhanced oil recovery (MEOR)

Biosurfactants are employed in several industrial applications which require a high purity level. However, the downstream purification processes are responsible for a large portion of the expenses incurred by biosurfactant production plants. The high costs associated with these processes turn their...
