Alcohol oxidase is widely used in biochemical and industrial applications due to its ability to catalyze the oxidation of alcohols to their corresponding aldehydes or ketones. In biotechnology, it plays a crucial role in biosensors for detecting ethanol and other alcohols, making it valuable in medical diagnostics, food quality control, and environmental monitoring. Additionally, it is employed in the production of fine chemicals and pharmaceuticals, where selective oxidation of alcohols is required. In research, alcohol oxidase is utilized as a model enzyme for studying enzyme kinetics and protein engineering. Its application in biofuel production is also being explored, as it aids in the conversion of alcohols into more efficient energy sources.
