ABSTRACT
One factor at a time design and first order exponential model were applied to investigate the effects of the four major factors(temperature,ionic strength,pH and osmo-regulator) in the preservation process of nitrite oxidization bacteria(NOB),and a first order decay kinetics was introduced.The result showed that the anoxic decay rate of nitrifying bacteria reduced from 0.25 to 0.015,the half life was extend to 53d at 4℃,pH7.60,ionic strength 0.035mol/kg.The protecting effect of glycerin showed obviously better than that of other cryoprotectants at 4℃.
