Short-cut nitrification mixed bacteria culture, freeze-drying preservation and rapid activity recovery method

The invention discloses a short-cut nitrification mixed bacteria culture, freeze-drying preservation and rapid activity recovery method, which adopts glycerol as a protective agent in a short-cut nitrification mixed bacteria freeze-drying preservation method so as to eliminate the adverse effect of the existing common vacuum freeze-drying method. The method for quickly recovering the activity of the short-cut nitrification mixed bacteria after cold-drying preservation is provided, the activity can be recovered after about 3 days, and the nitrite conversion rate after activation can reach 90% or above. 本发明公开了一种短程硝化混合菌培养及冷冻干燥保存与快速恢复活性的方法，本发明采用甘油作为短程硝化混合菌冻干保存法中的保护剂，以消除现有常见真空冷冻干燥方法的不利影响，提供短程硝化混合菌冷干保存后的快速恢复活性的方法，可以达到3天左右恢复活性，活化后亚硝转化率可达90%以上。
