Gut Bacteria (was Re: Gut sounds)

Some questions or is it snowflakes.

1. Aren't bugs responsible for the fermentation that is causing the gas?
2. Aren't there several different varieties of bugs whose proportion
change depending on the food that is eaten? Isn't that why rapid food
changes sometimes lead to colic and laminitis?
3. Could some bugs cause more gas than others?

Any research behind any of this?
