Generally, the germs grow and reproduce in the greenhouse environment, and the low-temperature environment stops growing and can only sustain life. However, Yersinia is not the opposite. It is not only not afraid of low temperature and cold, but also multiplies only at about 0 degrees Celsius. Keep Yersinia optimally. From this we can infer:. ['Yersinia cannot survive at room temperature.', 'The environment for general bacteria growth is also suitable for Yersinia growth.', "Yersinia's optimal growth temperature is not suitable for general pathogens.", 'Only Yersinia bacteria are present in the refrigerator at 0 degrees Celsius.']
