N2  - fermentor was carried out using Bacillus subtilis
MTCC 2423 at 45°C. A good yield was obtained from sucrose
(2%) substrate fermentation by continuous removal of the
product by foam fractionation. The biosurfactant was recovered from collapsed foam by acid precipitation. The biosurfactant yield (4.5 g/L) was about 4.5 times higher than the yield (ca. 1 g/L) obtained by shake-flask fermentation. Surface activity of the collapsed foam was very high, and total surface activity was observed in the collapsed foam. The structural characterization
of this biosurfactant produced at 45°C by the strain used
in this study was recently reported. The biosurfactant was analyzed by thin-layer chromatography, infrared, 1H nuclear
magnetic resonance, and mass spectroscopy and was found
to be identical to surfactin, a lipopeptide surfactant.
