Fermentative production of mono-rhamnolipids pilot scale - challenges of large scale

The fermentative production of biosurfactants is usually hampered by the excessive formation of stable foam. Using the example of monorhamnolipids, proposals both for stable maintenance of gassed and stirred fermentations as well as for the isolation of these biosurfactants on a larger scale are giv...

Description
Summary:The fermentative production of biosurfactants is usually hampered by the excessive formation of stable foam. Using the example of monorhamnolipids, proposals both for stable maintenance of gassed and stirred fermentations as well as for the isolation of these biosurfactants on a larger scale are given, as these are commercially available only in very small quantity. A special focus is on the use of renewable resources.Original Abstract: Die fermentative Herstellung von Biotensiden wird meist durch die exzessive Bildung von stabilem Schaum erschwert. Am Beispiel von Monorhamnolipiden werden Vorschlaege sowohl zur stabilen Aufrechterhaltung von begasten und geruehrten Fermentationen wie auch zur Isolierung dieser Biotenside im groseren Masstab gegeben, da diese kommerziell nur in sehr kleinen Mengen erhaeltlich sind. Ein besonderer Fokus liegt dabei auf der Verwendung nachwachsender Rohstoffe.
