From the results, an aeration rate of 300 mL/min and foam fractionation column height of 60 cm were optimal for foam frac-tionation. Using these conditions, one liter of diluted culturemedium with palm oil and crude palm oil additions could beseparated and concentrated to 167 and 200 mL of foamate con-taining 10.9 and 9.8 g/L of crude lipopeptide, respectively. Theselipopeptide yields were much higher than the integrated lipopep-tide production and recovery processes designed by Yeh et al.[5], which consisted of a conventional stirred tank fermenter con-nected with foam separation through its gaseous outlet column.Using 1.5 mL/min aeration rate and 300 rpm agitation, Yeh et al.[5] reported the highest lipopeptide concentration in foamate of6.45 g/L. The high lipopeptide yield could be due to the lower aer-ation and agitation rates used in this study, which resulted in lessshear force on the immobilized cells. Moreover, the sequentialproduction and recovery processes could reduce the risk of contam-inations in the fermenter compared to the integrated processes
