WebAn ultrasound, a non-thermal technique, can be employed to increase a probiotic’s biomass and its fermentation products. The effects of high-intensity ultrasounds (20%, 30%, and 40% amplitudes for 3 min) on the growth and fermentative profile of Lactobacillus acidophilus and helveticus were studied. The use of an ultrasound decreased the Lag phase and …
WebThe frequencies of diagnostic ultrasound are roughly 1 - 10 megahertz (MHz) or 1 000 000 to 10 000 000 cycles per second. It is a form of energy and, as such, may have effects in tissues it traverses.
