Production of Rhamnolipid Biosurfactant by Fed-batch Culture of Pseudomonas aeruginosa Using Glucose as a Sole Carbon Source

Abstract

  The pH-stat fed-batch culture of Pseudomonas aeruginosa YPJ-80 was done to produce a rhamnolipid biosurfactant. With glucose as the sole carbon source, the final concentrations of cells and rhamnolipid biosurfactant obtained in 25 h were 25 g cell dry weight/l and 4.4 g/l, respectively.
