Characterisation of colloidal gas aphrons for subsequent use for protein recovery

摘要

Colloidal gas aphrons (CGAs) were first reported by Sebba (J.Colloid Interface Sci., 35 (4) (1971) 643) as micro bubbles (10-100 um), composed of a gaseous inner core surrounded by a thin surfactant film, which are created by intense stirring of a surfactant solution. Since then, these colloidal dispersions have been used for diverse applications (clarification of suspensions, removal of sulphur crystals, Separation of organic dyes from wastewater, etc.). However, there have been no reports, as yet, of their direct application for protein recovery.
