EVALUATING THE RESPONSE OF ARTIFICIALLY LIGNIFIED MAIZE CELL WALL TO PRETREATMENTS AND ENZYMATIC HYDROLYSIS

摘要：

Lignification was undoubtedly a crucial innovation for the structural development of large terrestrial plants; its malleability provides opportunities for engineering the composition and consequent properties of lignin. In the present study, microscale analysis methods were developed to evaluate the response of the artificially lignified maize cell wall containing coniferyl alcohol to pretreatment methods (dilute sulfuric acid and sodium hydroxide pretreatments) and enzymatic hydrolysis. Pretreatment parameters such as treatment temperature and chemical loading were conventionally optimized as well. It was found that pretreatment temperature greatly influenced the enzymatic digestibility of the lignified cell walls. The conditions of 100°C, 60 min and 2.5％ w/w chemical loading were found to be appropriate and suitable for the pretreatment of the artificial cell walls.
