摘要
本文基于SPSS多元线性回归分析乙酸钠为底物添加针铁矿后的小瓶实验中的微生物群落进行研究,阐明了产甲烷过程中的细菌和古菌之间的关系。结果表明,乙酸钠为底物添加针铁矿产甲烷过程中的微生物丰富,存在多种细菌和古菌。针铁矿、Pseudomonas、Brochothrix、Bacillus与产甲烷菌具有明显的线性相关性,其中针铁矿和Bacillus对Methanothrix呈现正相关,Brochothrix和Pseudomonas呈现负相关,对Methanosarcina则相反。
In this paper, the microbial community in the vial experiment after addition of iron ore with sodium acetate as substrate was studied to analyze the relationship between bacteria and archaea in the process of methanogenesis. The results showed that sodium acetate as a substrate added during the production of goethite methane is rich in microorganisms, there are a variety of bacteria and archaea. By statistical analysis of the relationship between microorganisms, it was found that goethite, Pseudomonas, Brochothrix, Bacillus and methanogens have a significant linear correlation, in which goethite and Bacillus show positive correlation with Methanothrix and Brochothrix and Pseudomonas show negative correlation. The opposite is true for Methanosarcina. There is no obvious linear relationship between other species and substrates.
