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.
