Webchromatography. Polyphenol oxidase activity was measured spectrophotometrically at 420nm using catechol, dopamine and chlorogenic acidassubstrates.Optimum pH,temperature,andionic strength were determinedwith threesubstrates.Thebest substrate of dill PPO was found to be chlorogenic acid. Some kinetic properties of the enzyme such … Webrespectively. Optimum temperature of polyphenol oxidase may change depending on the type of the used substrate. Ziyan and Pekyrdimic (2004) studied the effect of seven different substrates on the optimum temperature of Ankara pear PPO. They found that these temperatures ranged from 20oC (for catechol as substrate) to http://complianceportal.american.edu/what-is-catecholase.php phone number for google workspace
