Mechanism Study of Tolerance of Immobilized Nitrifying Bacteria Towards Low Temperature
固定化硝化细菌耐低温机理的研究

Immobilized Nitrosomonas europaea and Nitrobacter agilis were found to be less sensitive to low temperature than their suspended cells. In order to explore its mechanism, activation energies for the maximum specific respiration activity, for the Monod constant and for the oxygen diffusion in carrageenin were determined and compared. It was shown that both the effect of diffusion limitation and the effect of temperature on the Monod constant were responsible for the better tolerance towards low temperature.
