Can bad bacteria form on the sauerkraut under the brine

[rajeshmarndi]

Also does bad bacteria(mold) forms on the weight(i.e use to submerged the cabbage) ,on the portion that is above the brine. I use glass paper weight, as I think they only form on food surface.

My thought, sauerkraut is safe, as long it is submerged inside the brine and mold formation is only above the brine surface.

Thanks a lot.
