## Abstract A novel technique for immobilization of __Candida rugosa__ lipase onto anionic colloidal gas aphrons (CGAs) is described. CGAs are spherical microbubbles (10โ100 ฮผm) composed of an inner gas core surrounded by a surfactant shell. In this initial study, greater than 80% lipase (w/w) was

## Abstract The variation of air holdup and stability of colloidal gas aphrons (CGAs) with stirring time, surfactant concentration [6, 8.1, 10, and 12 mM sodium lauryl sulfate (SLS)], and stirring speed (3500โ7000 rpm) was investigated, and an empirical correlation between the air holdup and stirri
## Sebba (1987) defined colloidal gas aphrons (CGA) as microbubbles stabilized by surfactant layers, which are created by stirring surfactant solutions at speeds greater than a critical value. A high shear impeller is used for stirring and critical values for the impeller speed must be exceeded to
The effect of ionomer structure on gas transport properties of membranes was investigated. For this purpose physical and transport properties of poly(phenylene oxide) (PPO) and its sulfonated derivative (SPPO) were compared. SPPO has a more rigid structure and a lower free volume, which determines l
