“…38 As reported in our earlier publication, 32 the hydrolytic study of olive oil was done by a physically adsorbed lipase immobilized matrix, whereas in this study, it was done for the three oils (olive, palm, and castor oils) by an immobilized matrix covalently coupled and physically adsorbed As pH affects the stability, structure, and function of many globular proteins because of their ability to influence electrostatic interactions, the extent of hydrolysis is different at different pHs. One determines the optimum pH for the hydrolytic reaction by conducting the reaction at different pH values (5)(6)(7)(8)(9). Figure 7 shows the variation of hydrolytic activities with pH for olive oil.…”

“…[2][3][4] The target of immobilizing enzymes is to restrict their mobility over solid matrices without losing their activities. 5 Noinville et al 6 showed that lipases in immobilized condition are in open form, that is, without lids and capable of showing better activities.…”

“…At low glutaraldehyde concentration, all amine groups of support matrix remain unutilized; while high glutaraldehyde concentrations lead to multi point attachment of enzyme. Suitable glutaraldehyde concentration varies with protease being used 1% for mungbean thiol protease [32], 5% for acylase [41] while 2% for papain [42]. Hence, there is need to determine suitable glutaraldehyde concentration, where, higher hydrolytic activity is obtained with minimal enzyme load.…”

“…Glutaraldehyde is easily available at cheaper rates it reacts rapidly with amino groups to form thermally and chemically stable complexes [30]. Researchers have reported suitability of glutaraldehyde coupling for different types of proteases [30][31][32][33][34]. Random glutaraldehyde activation followed by protease coupling may lead to low or multiple binding which adversely affects protease activity.…”
