detection of ruminal bacteria that degrade toxic dihydroxypyridine compounds produced from mimosine.leucaena leucocephala, a tropical leguminous shrub, contains a toxic amino acid, mimosine. successful utilization of leucaena as a ruminant forage depends on colonization of the rumen by bacteria that degrade dihydroxypyridines (dhp), which are toxic intermediates in the metabolism of mimosine. populations in the rumina of animals in some parts of the world, however, do not include bacteria that are able to carry out this degradation. we thus describe tests for the presence of dhp degraders in r ...19902317038
