Catalase from bovine liver is widely used in industrial and laboratory applications due to its ability to rapidly decompose hydrogen peroxide into water and oxygen. It is commonly employed in the food industry to remove hydrogen peroxide during the processing of milk for cheese production, ensuring product safety and quality. In textile manufacturing, it helps in eliminating residual hydrogen peroxide after bleaching processes, reducing environmental impact and improving fabric quality.

In molecular biology and cell culture labs, this enzyme is used to protect sensitive biological molecules from oxidative damage by removing hydrogen peroxide generated during metabolic reactions. It is also utilized in biosensors and diagnostic kits where control of peroxide levels is critical for accurate measurements. Additionally, catalase finds use in cosmetic formulations to reduce oxidative stress in skin products and enhance stability. Its high specificity and efficiency make it valuable in research settings for studying oxidative stress and antioxidant defense mechanisms.
