摘　　要：为构建绿色木霉菌液态发酵产黄色素动力学模型,在绿色木霉菌分批发酵过程中测定了菌体干重、总糖浓度、黄色素色价和pH变化,使用Origin软件将经典发酵动力学方程拟合后得到绿色木霉菌菌体生长、黄色素合成和基质消耗的动力学模型及参数。结果表明,模型与实验数据两者能较好地拟合,可以较好地预测发酵过程。In order to set up the kinetices model with the liquid state fermentation of yellow pigment by Trichoderma viride,during the producing of yellow pigment,the net weight of thallus,the density of total suger, valeur and pH degree were tested. Then classical fermentation kinetic equation of yellow pigment was simulated with the origin software. Results showed that they matched well,and the models can predict fermentation perfectly.
