Effect of the carbon source on biosurfactant production byPseudomonas aeruginosa 44T1

Pseudomonas aeruginosa 44T1 produces rhamnolipids when grown on C12 n-alkane but not with other hydrocarbons tested. Best results were obtained with olive oil as carbon source; a final production of 7.65 g rhamnolipid/l with a production yield of 38.2% was detected.
