DESCRIPTION:Separation technologies which take advantage of the high gas-l
 iquid interfacial areas available in foams have found widespread applicati
 on. For example\, the attachment of fine hydrophobic particles to foam int
 erfaces is the basis of froth flotation and is used to process some 2 bill
 ion tonnes of mineral ores annually. Foam fractionation is froth flotation
 's cousin\, being based on the adsorption of surface active molecules to f
 oam interfaces\, but for the past 50 years has been the poor relation. How
 ever\, the growth of biotechnology and the need for economical means of se
 parating surface active molecules produced by living organisms (biosurfact
 ants) will change this and has led to renewed interest in developing foam 
 fractionation technology. This presentation will deliver an overview of fo
 am fractionation and its integration with fermentation\, with emphasis on 
 recent work into surfactin production.
