| 摘 要： | 在20 ℃及0.1~430 MPa压力范围内，不同的静水压力与不同的保压时间相结合，对接种了大肠菌群的牛奶做高压处理，研究大肠菌群的耐压性。结果表明：40 MPa压力难以杀死大肠菌群；100 MPa压力持续5 min，大肠菌群中70%以上的细菌死亡；直到430 MPa，大肠菌群中仍有少量耐压细菌存活。

| Abstract: | In order to investigate the pressure-resistance of the coliforms, the milk samples inoculated with coliforms were treated at 20 ℃ and the pressures ranging from 0.1 to 430 MPa for 5 or 15 min. Results show that the most coliforms can survive at 40MPa.More than 70% of the coliforms, however, were killed under pressure of 100 MPa for 5 min. A few of pressure-proof coliforms still survived at pressures up to 430 MPa. |
