Biotransformation of phenol using immobilized polyphenol oxidase from banana stem
Polyphenol oxidase(PPO) is an enzyme that can easily find in most of the plants.It is a browning agent that cause from catalyzing the oxidation of various phenolic compounds to the corresponding quinones which lead to the formation of melanin pigment.PPO commonly used as biocatalyst in a biotransfor...
