摘要

Abstract

Metal elements in the environment have a certain impact on key transformation processes in microbial metabolic path-ways.In order to study the effect of trace metal elements on the metabolism of microorganisms,the methane-oxidizing bacterial communities were screened from nature,and four representative metal elements,Cu2+,Fe2+,Mn2+,and Zn2+were selected.The meth-ane oxidation laws of microbial communities under different mass concentration conditions were obtained through experiments.The research results showed that Cu2+and Fe2+had a significant impact on the methane oxidation efficiency of bacterial communities.When the mass concentration of Cu2+was 0.03 g/L,the bacterial communities achieved their best CH4 degradation effect,with the highest CH4 degradation amount reaching 33.43 mL within 6 days;compared with Cu2+,the effect of Fe2+was more significant,with the increase of Fe2+mass concentration(0-0.6 g/L),the methane oxidation efficiency of the microbial community was gradually en-hanced,and the amount of CH4 degradation could be significantly increased from 13.02 mL to 37.28 mL within 6 days;Mn2+and Zn2+had a weak effect on the methane degradation efficiency of the microbial communities.When the mass concentrations of the two ions were 0.003 and 0.010 g/L,respectively,they had the best promoting effect on the methane oxidation efficiency of microbial communities,and the methane oxidation ability was weakened by elevating or decreasing the concentrations.
