| Abstract: | The facultative anerobic fermentation kinetics of degradating corn straw cellulose with a filamentous fungus isolated from the rumen of sheep was investigated in this paper.Based on Logistic equation and Luedeking-piret equation,the kinetic models describing cell growth,product synthesis and substrate consumption were obtained,respectively.The kinetic model was validated.The correlation coefficient of the model with experimental were 0.98827,0.98283,and 0.99599.The results showed that the models were again ... |
