For an excellent AD starter culture I have used the contents of a freshly slaughtered cow's stomach, preferably the first unit which contains the methano-bacteria, rather than the others. I have also trialed septic tank biological cultures in dried and pelleted forms as long as anaerobes are part of the cultural mix.
