Amy Robertson asked Michael Pollan:

We're hearing a lot about probiotics. Is commercially produced kimchi, sauerkraut, cheese still probiotic?

Michael Pollan If the sauerkraut or kimchi is in the refrigerated section, it contains live cultures-- probiotics. However, if it is not refrigerated, it's been pasteurized (which the jar may tell you), meaning the bacteria have been killed.
