Evidence of vegetables absorbing bacteria – organics?

Hi Scott, Have just discovered your great site, and am beginning to investigate hydroponics - always thought it was a huge amount of effort, etc, but it seems maybe not. I've been an organic gardener for years - am really interested in finding out more about what you've said about vegetables absorbing bacteria from animal manures - where can I find some facts and details of research on this ? do you know any sites? Many thanks. Siobhan
