由纤维素制取单细胞蛋白的反应机理模型

REACTION MODEL ON THE PRODUCTION OF SINGLE CELL PROTEIN FROM CELLULOSE

对灰黄链霉菌№.107利用纤维素制取单细胞蛋白的生化过程,提出了一个简化的机理模型、并建立了一个含4个状态变量的状态方程组的数学模型,其中包含9个待优化的参数.根据现有的实验数据,借助VAX-ll/780计算机的STYR/OPT库的优化程序,确定了这9个参数,并对模型内多组分不同的动力学表达式进行了比较.对实验模拟的结果是令人满意的.

For the preparation of single cell protein from cellulose with Strep-tomyces No. 107, a simplified reaction model has been established based on the mathematical model developed by Armiger-Humphrey. The model consisted of 4 ordinary differential equations including 9 parameters to be estimated. Using the VAX-11/780 computer and a STYR/OPT optimization program developed in this Institute the parameters included in the model were estimated by optimization and the experimental results were simulated by the model satisfactorily. The value of the 9 parameters optimized were reasonable and the simulation of experimental results was successful.
