| 英文摘要 | Soil beta-glucosidase participates in the final step of cellulose biodegradation. It is significant in the soil C cycle and is used as an indicator of the biological fertility of soil. However, the response of its kinetic parameters to environmental temperature and moisture regimes is not well understood. This study tested the beta-glucosidase response in the main agricultural soils (black soil, albic soil, brown soil, and cinnamon soil) of Northeast China. Incubation tests were conducted to measure the kinetic parameters K(m), V(max), or V(max)/K(m) of soil beta-glucosidase at environmental temperatures of 10,20 and 30 degrees C and at 10,20 and 30 % soil moisture content. The insensitive response of the kinetic parameters to temperature changes indicates that soil beta-glucosidase was present primarily in immobilized form. The significant response of the kinetic parameters of soil beta-glucosidase to soil moisture rather than to environmental temperatures suggests that the catalytic ability of soil beta-glucosidase was sensitive to changing soil moisture regimes. |
