【摘要】 以稻壳和麸皮混合物为基质,进行纤维素酶固态发酵动力学的研究。以氨基葡萄糖含量表征生物量,建立了纤维素酶固态发酵过程中细胞生长、产酶和二氧化碳释放速率动力学模型,并得到模型参数。动力学分析结果表明,在不同培养温度和基质配比下,最大菌体量与最大酶活呈正相关;在适宜培养温度下,预期最大酶活与最大CO2释放速率也呈一定的正相关关系。
【英文摘要】 In this paper,kinetics of cellulase production by solid-state fermentation was studied using the mixture of rice husk and wheat bran as substrates.With measured glucosamine for biomass estimation,models for microorganism growth,cellulase(Filter Paper Activity,FPA) pro-duction and carbon dioxide production rate(CPR) were proposed and the model parameters were fitted.Positive correlation was shown between the maximum FPA and the maximum glucosamine,which was also found between the maximum CPR and the anticipa...
