- 摘要：
Microstructure changes and micro-damage behavior of some LAB under the impact of
ultrasound shock (20 kHz for 5, 10, 15, 20, 25 and 30 minutes) was studied by optical microscope and
Transmission Electron Microscope (TEM). Three kinds of micro damages are usually produced by
ultrasound, micro-cracks, micro-voids and ruptures.Studies, by TEM showed that ultrasound can increase
the cell wall permeability of the cells, which is important in the release of enzymes such as ß-galactosidas
reduction of the coagulation time. The survival of LAB was very low in very long exposures of ultrasound. - 关键词：Ultrasound;shock;Cell Walls;Permeability;Survival;Milk
