Although the above mentioned studies have provided insight into the mechanisms of ruminal microbial degradation of mycotoxins, the complete pathways, rates, and extents of such degradation have not been elucidated. In vitro studies have shown that specific strains of Lactobacillus bacteria can bind to AFB1 (El-Nezami et al., 1998). It has not been determined whether factors such as bacterial binding or the presence of other micoorganisms in the motile rumen environment are conducive to AF biodegradation. This evidence indicated that the motile rumen environment could expedite or delay the biotransformation of other mycotoxins such as tricothecenes (Cook et al., 1986).
