| Additional Information: | Extraction of enzymes/proteins by organic solvents using reverse micelles offers a number of unique features that makes it a promising bioseparation technique. The reverse micelles provide a gentle and friendly environment for biomolecules by holding them in their water core. The ability of a reverse micellar system to solubilize the biomolecule depends upon the surfactant/solvent combinations and other processing conditions such as aqueous phase pH, surfactant concentration, addition of co-solvents etc. The water content of the organic phase in a reverse micellar extraction is normally considered as an index of extraction efficiency. In the present investigation, the ability of the surfactant/solvent combinations to form reverse micelles was studied based on the water content of organic phase (measured by Karl-Fischer method). Two different solvents (Toluene and Isooctane) and three surfactants (AOT, CTAB and Triton X-100) were selected for the study. Toluene gave higher water content with all the three surfactants. Ionic surfactants (CTAB and AOT) gave good results compared to nonionic surfactant (Triton X-100) for both the solvents. |
