Although the path is not known, it has also been shown that some 
soil microorganisms can open the triazine ring and degrade it to CO, (573, 
574, 1030, 1172, 1188). Fungi metabolized the side chains but did not open 
the ring to any appreciable extent (309, 770). 
A number of fungi capable of degrading simazine were isolated and 
identified (143, 767, 1003).
