1 The process parameters, such as the pH value, temperature and enzyme dose, were discussed for PPO-catalysed oxidation of 1-naphthol. 1-naphthol protoporphyrinogen oxidase Homo sapiens
2 The optimum conditions of enzymatic oxidation of 1-naphthol were determined to be pH 8.0 and 40 C. Under the optimum conditions, PPO-catalysed oxidation of 1-naphthol increased with an increase in the enzyme dose. 1-naphthol protoporphyrinogen oxidase Homo sapiens
