Just a quick comment. The statement in the article:
'Ultrasonication is a non-thermal processing alternative'
is misleading as ultrasound does produce heat, so it would be about the intensity and time. Normally when used to disrupt biological materials in a lab setting, the container is surrounded by ice to stop the temperature from rising toohigh as a result of ultrasound exposure. Microbes are not easily (efficiently) killed by low level short exposure (especially the bacterial cocci). Would suggest including a thermocouple in any experiments where the ultrasound would be used, in order to eliminate the likelihood of effects from excessive heating. Possible to find a sweet spot though, I would expect.
