It is my opinion that all anaerobes extract<br>oxygen from their substrate. Therefore, I feel that in addition to<br>digestibility, the oxygen content of the substrate is also an<br>important factor.In fact, the two go hand in hand. A substance devoid<br>of oxygen cannot be digested (e.g. plastic, petroleum)<br>Yours<br>A.D.Karve<br>***<br>Dr. A.D.
