Hum, I do understand the impulse, but I don't think a CV is the right place for that. You don't want it to look like the back cover of a crime novel :)
In my country (France), PhD thesis undergo both a peer-review and a formal defense. Thus, you usually come out of it with two written reviews of your thesis, and one written review of your defense. It would be quite uncommon to quote these in a CV, but in many applications it is fine (and sometimes mandatory) to actually attach them to the application, as supporting material.
So, unless it is common to do so in your system, I wouldn't recommend quoting praise for yourself in a CV (a CV is a list of facts, mainly, not opinions), but you can try to include it in the application if it is allowed. Either raw, or you could quote it in the application letter, statement of intent, summary of your work, whatever:
The research topic of my PhD was to study the influence of UV irradiation on bacterial growth rate in the lab's fridge. I quantified the extent to which it was detrimental to the life of these poor innocent bacteria. I also made the case for a new classification splitting part of the UV range currently known as “UV-C” radiation into a new “UV-D” category, based on its distinct harmful effects on fungal growth.
This work was well received by the community, with a total of 4 published papers and 3 conference talks during my PhD. The thesis peer-review committee called it “a brave and well-inspired revolution of the old dusty classification of UV radiation” and characterized the end product of the thesis as “a clean lab fridge: the greatest service you can render mankind or, at least, labkind”.
