Nope,
Pasteurization is heating the beer above 180F to kill all bacteria, and this process also kills the yeast. Once the beer is pasteurized, the yeast that were in it at the time of pasteurization are no longer viable.
What exactly are you trying to accomplish? Are you trying to harvest yeast from a commercial beer, or did you pastuerize your own homebrew, and if so, why would you do that?
