Uaing Em to make cultured veggies?

I have read about using kefir grains, Veggie Starter packets, and whey to hasten the fermentation of veggies, but what about Effective Microorganisms? Has anyone tried this or think that it would work? The starter packets are outrageously priced and a friend told me that all the fermented veggies she made with whey tasted like feta cheese. That sounded very unappetizing, even though I love feta.
Let me know what you think. Cordon Tweet
