I didn't know about most of these fermented soy products - https://en.wikipedia.org/wiki/List_of_fermented_soy_products

But Tempeh is a pretty common one for vegans. I've used it in curries and stir fries.

I think the problem is that Tempeh is always cooked, so I would expect any critters in there to be dead (not that they haven't done good work making it more digestible).
