- Degradation of euptox A by tannase-producing rumen bacteria from migratory goats (2017), J. Appl. Microbiol., 123, 1194-1202 .
Application
| Application | Comment | Organism |
|---|---|---|
| agriculture | hydrolysable tannins, the derivatives of gallic acid (3,4,5-trihydroxyl benzoic acid) are toxic when taken in excess, leading to significant economic losses by morbidity and mortality in animals. The bacterium from rumen microbium producing tannase which catalyses degradation of hydrolysable tannins, and concurrently degrading euptox A, may have potential as microbial feed additives to increase utilization of plant biomass containing antinutritional phytometabolites | Klebsiella pneumoniae |
