Summary, etc. <p>The conductivity as well as surface tension measurements have carried out to study the interactions among cetyltrimethyl ammonium bromide (CTAB), sodium dodecyl sulpahe (SDS) with α-chymotrypsin (α-CT) and trypsin in aqueous medium on pH 7.75. The surface parameter <em>i.e.,</em> critical micelle concentrations (CMC), the maximum surface excess concentration (<em>Γ</em><sub>max</sub>), minimum area per surfactant molecule (<em>A</em><sub>min</sub>) and the surface pressure at CMC (<em>π<sub>cmc</sub></em>), and thermodynamic parameters <em>i.e.,</em> degree of ionization (α), Gibbs free energy of micellization (ΔG°<sub>m</sub>), the standard Gibbs energy of adsorption (ΔG°<sub>ads</sub>)<sub>, </sub>the free energy at air-water interface (ΔG<sup>s</sup><sub>mim</sub>) have been evaluated using surface tension and conductivity measurement. Thermodynamic parameters indicate that enzyme-CTAB/SDS monomeric aggregation started to form micelles at a higher concentration of surfactant to compare with the CMC of pure CTAB/SDS micelles.</p>
