Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide but is also used to control larger pests such as possum.ompound 1 is the starting ester needed to synthesize brodifacoum.

Bifidobacterium is a genus of Gram-positive, nonmotile, often branched anaerobic bacteria. They are ubiquitous, endosymbiotic inhabitants of the gastrointestinal tract, vagina and mouth (B. dentium) of mammals, including humans.he primary factor responsible for aerobic growth inhibition is proposed to be the production of hydrogen peroxide (H 2 O 2) in the growth medium. A H 2 O 2 -forming NADH oxidase was purified from O 2 -sensitive Bifidobacterium bifidum and was identified as a b-type dihydroorotate dehydrogenase.
