| 英文摘要: |
| A kinetic model for growth of A. ferrooxidans was deduced on the basis of theMonod equation, the values of kinetic parameters
( i. e. Monod constant K, maximum growth rateLm and R0) in different initial experiment conditions were calculated by using Gauss- Newton
algorithm. Through the researching of the growth characteristics of under the conditions, the kinetic equation for growth of A. ferrooxidans, which
was represented by restricted substrate ferrous ion concentration under the corresponding conditions, was obtained, which, theoretically, revealed
the influence of the kinetic parameters on the growth of A. ferrooxidans, and the numerical simulation in kinetic equation for growth of A. ferrooxidans
was proved to be consistent with the experimental data. |
