The bacteria that ferments tempeh doesn't produce b12. There was a study where they tested random samples of tempeh from some street markets in jakarta and some had varying amounts of b12, probably from contamination with bacteria that does produce b12. Tempeh sold in the west does not have b12, there's more food safety regulations and it's fermented in an otherwise sterile environment.
