Effects of Glucose and Ferrous Supplements and Culture Conditions on Lipopeptide Biosurfactant from Pseudomonas spp.
Thanawat Choopraserdchok, Dusit Athinuwat, and Pumnat Cheunchomrat
Abstract—To enhance lipopetide biosurfactant production
by Pseudomonas spp., the effects of medium and culture
conditions were investigated. Nutrient broth (NB)
supplemented with glucose and molasses as carbon sources
were used to increase biosurfactant yield. Cultivation
temperatures and initial pH were also studied. In this
experiment, NB was used as a control to produce biosurfactant
with the yield of 0.58 g/L. The lipopeptide biosurfactant yield
was increased to 2.76 g/L when Pseudomonas spp. was cultured
in NB supplemented with 1% w/v glucose, 500 μM FeSO4, pH
9.0 and cultivation of 20°C for 72 h. Its specific growth rate was
0.25 h-1.
Index Terms—Pseudomonas spp., lipopeptide biosurfactant, glucose, ferrous.
