响应面法优化糙皮侧耳的木质素降解条件OA

This experiment mainly used agricultural waste corn straw as the main raw material,with lignin degradation rate as the indicator,and combined the results of single-factor experiments to optimize the response surface methodology to determine the optimal combination of inoculation amount,water content,and cultivation time.And scanning electron microscopy and infrared spectroscopy were used to analyze the microstructure and chemical structure of the raw materials before and after the optimization process of Pleu-rotus ostreatus.The results showed that when the inoculation amount was 15％,the water content was 80％,and the cultivation time was 40 d,the lignin degradation rate was the highest,reaching 34.71％.Through electron microscopy and infrared spectroscopy analysis,the surface structure of the raw material was dam-aged,the fiber bundle structure was exposed,and the chemical structure significantly changed after the opti-mization process treatment of Pleurotus ostreatus.This indicates that the Pleurotus ostreatus has a good deg-radation effect on lignin in corn straw.
