摘要
The potential of high-pressure-resistant mutants of Escherichia coli to survive high-pressure pasteurization in fruit juices and in low-pH buffers was investigated. Treatments with up to 500 MPa of pressure caused only a limited direct inactivation of the mutants but resulted in an accelerated low-pH inactivation during subsequent storage.
