Bacterial population structure diversity in saline-alkali soil in Hexi corridor
摘要
Abstract
Salinization of soil is one of the main reasons causing the deterioration of soil ecological environment, and the remediation and utilization of saline-alkali soil is the focus of current research. By building 16S rRNA gene library, this article reveal the diversity of bacterial population structure at the saline-alkali soil in the Hexi corridor in northwest China. Statistical analyses show that the significant difference in the composition and abundance of bacterial population structure exist in the primary saline-alkali soil, the secondary saline alkali soil and farmland soil. Three bacterial groups exist in the control soil, Firmicutes is the dominant population; Nine bacterial groups exist in the primary saline-alkali soil, Firmicutes and y-proteobacteria are the dominant population; existing a significant difference between the three samples of the secondary saline-alkali soil, y-proteobacteria is the common dominant bacteria group. The halophilic bacteria such as Marinobacter, Halomonas and Pseudomonas commonly are found in all saline-alkali soil.关键词
