| Research Abstract |
In the aerobic culture of Bacillus subtilis ATCC 21332 to produce a biosurfactant, foam control using a foam-breaking impeller fitted to a stirred-tank reactor succeeded. Production and enrichment of the biosurfactant were accomplished simultaneously in the stirred-tank reactor with the presence of the foam layer. The foam fractionation operation after the end of cultivation improved the recovery of biosurfactant up to 92.3%. The volume of treating liquid, which the biosurfactant was enriched, could be reduced. Therefore, this technique contributes to a lowering of running costs in separation and purification processes.
