Full TextAbstract
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). Results showed that after treatment, a large number of coccus LAB were alive, but the number of bacillus LAB declined, Three kinds of micro damages are usually produced by ultrasound, microcracks, 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 β-galactosidas and decreasing the coagulation time. The survival of LAB was very low in very long exposures of ultrasound. Keywords: Microstructure, cell wall permeability, LAB, ultrasound shock, survival
