Aims: The gut microbiota capable of degrading plant biomass and
antinutritional phytometabolites are of immense importance. This study
reports isolation and characterization of tannase-producing rumen bacteria
that could also degrade euptox A (9-oxo-10,11-dehydroageraphorone) present
in Eupatorium adenophorum (Spreng).
Methods and Results: Migratory Gaddi goats were selected as source of
inoculums for isolating rumen bacteria with ability to produce tannase which
catalyses degradation of hydrolysable tannins (HTs). Three rumen bacterial
isolates producing tannase were studied, and identified as Klebsiella variicola
strain PLP G-17 LC, K. variicola strain PLP S-18 and Klebsiella pneumoniae
strain PLP G-17 SC. The isolates exhibited optimal tannase activity at 40°C,
and pH 6 0. The bacteria could also degrade euptox A, a potent hepatotoxin in
E. adenophorum Spreng, a widely distributed noxious weed.
Conclusions: The rumen bacteria could degrade antinutritional HTs and
euptox A. Culture-independent metagenomic interventions are envisioned to
completely decipher the rumen microbial ecology and exploit its genetic and
metabolic potential.
Significance and Impact of the Study: The bacteria producing tannase which
catalyses degradation of HTs, and concurrently degrading euptox A, may have
potential as microbial feed additives to increase utilization of plant biomass
containing antinutritional phytometabolites.
