The enzyme catalase is known to catalyse the breakdown of hydrogen peroxide into oxygen and water. Hydrogen peroxide metabolism is mainly regulated by this enzyme. Catalase is a common enzyme found in nearly all living organisms. It has one of the highest turnovers of all enzymes as it has the capacity to decompose more than one million molecules of hydrogen peroxide, per molecule of enzyme. Catalase has been used as an important enzyme in many biotechnological areas including bioremediation. This paper gives a review of its use and application in the field of bioremediation as an indicator of hydrocarbon degradation in soil (an important aspect in bioremediation of crude oil pollution), as a provider of oxygen in aerobic bioremediation process and in the removal of H2O2 from bleaching industry effluent and also its potential use in the food industry.
The role of catalase enzyme in various aspects of bioremediation has been demonstrated by this review paper. Catalase has proven to be one of the most abundant and easily available enzymes of the microbial origin that can effectively act as an indicator of bioremediation step involved in the remediation of the crude oil polluted soil as its activity is highly affected by hydrocarbon pollution. It has also shown to provide oxygen by breaking down of hydrogen peroxide into water and oxygen during the aerobic bioremediation of wastes thus acting as a source of oxygen for the aerobic microorganisms. Its application in the removal of hydrogen peroxide from the bleaching effluents and making it possible for the water to be reused again for subsequent dying steps has been one of the main use this enzyme in bioremediation of waste effluents from textile industries. There is very little known about catalases from alkalithermophilic micro-organisms, although enormous progress has been made over the last few years in the research area of extremophiles. This class of catalase can solve many problems involved in the use of catalase by increasing its tolerance towards high temperature (above 60 0C) and high PH.
