Abstract

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.
