摘要
采用末端限制性片段长度多态性分析(T-RFLP)技术和16S rDNA克隆文库的方法,分析了黄河三角洲滨海湿地土壤不同深度细菌和古菌的群落结构.研究表明,随着深度的增加,细菌群落的多样性下降,而古菌群落多样性则有上升的趋势,且土壤的细菌和古菌群落结构都呈现出规律的层状分布.该土壤包括各种硫酸盐还原菌、产甲烷古菌、光合细菌等丰富的细菌和古菌资源.
Terminal restriction fragment length polymorphism and 16S ribosomal DNA （rDNA） clone library analyses were conducted to assess bacterial and archaeal diversities and community structures at different soil layers of the coastal wetland in the Yellow River Delta region. Shannon - Wiener index showed that the species richness of bacteria decreased with depth, while the richness of archaea tended to increase. Classification analysis showed that the bacterial and archaeal community structures subjected to stratified distribution. The wetland soil was very rich in resources of bacteria and archaea, including SRB, methanogenic archaea and phototrophic bacteria.
