Soybean peroxidase as an industrial catalyst
- Enzymol International Inc., Columbus, OH (United States)
Peroxidases are a large class of enzymes which are very efficient at catalysing oxidation reactions. Horseradish peroxidase, the most abundant and commercially available peroxidase, has been utilized for many years in medical diagnostic test kits but has never been used successfully in an industrial application. One of the major drawbacks associated with the peroxidases cost and has been their lack of the thermal stability required in an industrial process. Recently, we isolated has been their lack of the peroxidase from soybean seed coats. Soybean seed coats are a commodity product available year round in very large volumes. The useful operational temperature for the soy peroxidase is 40{degrees}C higher than for horseradish peroxidase resulting in shorter reaction times and greater reactor efficiency. This process can be used to produce formaldehyde-free polyphenols as well as numerous phenolic dimers used in the manufacture of anti-oxidants, U-V absorbers, epoxies as well as other materials. The process to manufacture resins and dimers will be discussed.
