Outline of Final Research Achievements

Ultra-deep sequencing of SSU rRNA retrieved from cecal feces of wild Japanese rock ptarmigans in Mt. Tateyama detected predominant bacterial species which were essentially absent in captive rock ptarmigans. From the literature, these specific bacteria were suggested to degrade toxic compounds in their natural foods and to be health beneficial. We isolated a range of intestinal bacteria from cecal feces of wild rock ptarmigans to test their capacities of toxin degradation. Strains of Lactobacillus plantarum showed the up to 30% of degradation rhododenol, a toxic compound in Rhododenrons which is a natural food for wild rock ptarmigans. Other isolates, namely Enterobacteriaceae, did not show the degradation of rhododenol.
After the project, we are still searching beneficial intestinal bacteria from cecal feces of wild rock ptarmigans.
