Adsorption procedures are significantly useful in the
immobilization of enzymes directly from the crude
homogenate and thus avoiding the high cost of enzyme
purification. The treatment of organic pollutants present in
industrial effluents based on peroxidases has attracted considerable
interest since the past two decades. However, practical
applications of large-scale enzymatic removal have always
been limited due to high cost and lower operational stability
of peroxidases. Moreover, this procedure emphasized the
immobilization of BGP directly from the crude homogenate
or ammonium sulphate precipitated proteins. It has further
reduced the cost of immobilized enzyme preparation. BGP
adsorbed on DEAE cellulose support showed very high yield
of immobilization and markedly high stabilization against
several types of denaturants. In near future, the enzyme
reactors containing such inexpensive immobilized enzyme
preparations could be exploited for the treatment of wastewater
containing toxic and hazardous compounds.
