Formaldehyde Dehydrogenase, derived from Pseudomonas sp., is primarily used in biochemical research and industrial applications for the detection and quantification of formaldehyde. This enzyme plays a crucial role in converting formaldehyde into formic acid, making it valuable in environmental monitoring to assess formaldehyde levels in air, water, and soil samples. It is also employed in biosensor development for real-time formaldehyde detection in industrial settings, ensuring workplace safety and compliance with environmental regulations. Additionally, this enzyme is utilized in metabolic studies to understand formaldehyde metabolism in microorganisms, aiding in the development of bioremediation strategies for formaldehyde-contaminated environments. Its specificity and efficiency make it a key tool in both analytical and applied biotechnology fields.
