Isn't it a bit more complicated than just making the terrain more aerobic? Over 99% of the bacteria in the gut are anaerobes, including most of the beneficial bacteria such as bifidobacteria, lactobicilli, eubacteria. etc. Plus, when conditions are such that aerobic bacteria flouish they can make infection by harmful anaerobes worse by using up all available oxygen and creating an environment favorable to anaerobes.
Or are you saying to create a "more" aerobic terrain but not an overly aerobic terrain? I would think that they key is balance, both in pH and in the ratio of good to bad bacteria (85% good to 15% bad).
Understand, I am not disputing you here - just looking for clarification, and I am quite ready and willing to be schooled where my understanding and knowledge is lacking.
