Pasteurized OP50

Has anyone tried to culture C. elegans using pasteurized OP50? Does anyone know how the pasteurized food affect behaviors and lifespan?

Is there a strict definition of “pasteurized”? When I look it up, I just find claims that it means to kill (or even just to mostly kill) bacteria, usually either using heat or radiation.

There is an extensive (if possibly somewhat scattered) literature using <a href=">uv-killed and heat-killed bacteria as a food source for C. elegans.

Thank you.
I have searched “heat-killed”, then I at least found these three papers showing a survival curve of C. elegans cultured by pasteurized OP50.
