Diversity analysis of rumen methanogens in buffalos using PCR-DGGE technique
摘要
Abstract
The present experiment was conducted to analyze the diversity of rumen methanogens in buffalos. [ Method ]The rumen contents were collected from sixteen local swamp buffalo in Guangxi to extract the total DNA, and the 16S rKNA gene sequences were amplified and analyzed using universal primers and DGGE technique. The obtained 7 dominant bands in DGGE gel were cloned and sequenced. [Result]After cloning, nine sequences were obtained, of which 5 were archaea and 4 were not. Three sequences amongst 5 archaea showed 99% homology with Methanobrevibacter, and one sequence showed 98% of homology with Methanobrevibacter. The other sequence unclassified in Euryarchaeota showed 98% homology with Thermoplasmatales. In addition, four non archaea sequences were belonged to Bacteroidetes Firmieutes and Proteobacteria, but their homologies were relative less. [ Conclusion ] DGGE technique was found useful in analyzing the diversity of rumen methanogens in buffalos.关键词
