| 摘 要： | 在20~120 MPa静水压力范围内，研究了压力对鲜牛奶中细菌的生长繁殖的影响。我们发现，在室温及20 MPa静水压下受压5 min后，细菌的生理活性显著降低，其生长繁殖受到抑制，而且生理活性的降低是一种压力非在位效应。

| Abstract: | The effect of pressure on growth and reproductive capacity of bacteria in raw freshmilk is studied in range of hydrostatic pressure from 20 to 120 MPa. The result is following:Atroom temperature and 20 MPa the raw fresh milk was pressed for 5 minutes then it was return tonormal pressure,the physiologic activity of bacteria in the raw fresh milk have a striking reduc-tion,this effect is the pressure effect in no situ. The effect of pressure up to 120 MPa have not ob-vious difference from that of 20 MPa. |

| Keywords: | bacterium physiologic activity pressure inhibition in no situ |
