| dominant bacterial communities in the rumen of gayals (bos frontalis), yaks (bos grunniens) and yunnan yellow cattle (bos taurs) revealed by denaturing gradient gel electrophoresis. | the dominant rumen bacteria in gayals, yaks and yunnan yellow cattle were investigated using pcr-dgge approach. the analysis of dgge profiles, identification of dominant bands and phylogenetic analysis 16s rdna sequences in dgge profiles were combined to reveal the dominant bacterial communities and compared the differences between those cattle species. dgge profiles revealed that gayals had the most abundant dominant bacteria and the lowest similarity of intraspecies between individuals than ot ... | 2010 | 21140219 |
