I echo Peter’s perspectives.

Bioaugmentation is still an emerging field and has been tried and implemented on a few full-scale AD facilities. What is more common -and often a must- is the addition of micro- and macro nutrients especially where mono-feedstocks such a corn silage is fed to the digesters.

Some facilities dose very specific micronutrients such a cobalt to compensate for nutrient deficiencies in the processed feedstocks.
