Glycerol dehydrogenase from Cellulomonas is primarily used in biochemical research and industrial applications. It plays a key role in the enzymatic conversion of glycerol to dihydroxyacetone, a process valuable in the production of chemicals like 1,3-dihydroxyacetone, which is used in cosmetics and pharmaceuticals. This enzyme is also employed in biosensors for detecting glycerol levels in various samples, aiding in quality control in food and beverage industries. Additionally, it contributes to metabolic studies, helping researchers understand glycerol metabolism in microorganisms. Its application extends to biofuel production, where it assists in optimizing glycerol utilization as a byproduct of biodiesel manufacturing.
