An enrichment experiment is conducted to screen rumen fluid for anaerobic bacteria capable of growing in the presence of high levels of "Acacia" condensed tannin. Four morphologically-distinct bacteria are isolated, confirming that resistance is a property shared by more than one organism. One isolate is chosen at random for further characterisation and is identified as a strain of "Selenomonas ruminantium" subspecies "ruminantium". It is arbitrarily designated strain K2. "Selenomonas ruminantium" K2 is shown to be not only tannin-resistant but also able to grow on tannic acid. It is proposed that this bacterium obtained energy for growth from tannic acid. The thesis examines the molecular mechanisms controlling tannin resistance or tannin degradation in rumen microorganisms. / Thesis (Ph.D.)--University of Adelaide, Dept. of Animal Science, 1997
