黄河三角洲及胶州湾滨海湿地沉积物中一氧化碳的微生物代谢及影响因素研究
Microbial Metabolism and Influencing Factors of Carbon Monoxide in Coastal Wetland Sediments of the Yellow River Delta and Jiaozhou Bay
摘要
Abstract
Carbon monoxide(CO)is an important trace reducing gas that can be utilized by marine mi-croorganisms as an energy source.In this study,we combined geochemical analysis and sediment culti-vation experiments to explore the in situ distribution characteristics,microbial metabolic pathways,and influencing factors of CO in the coastal wetland sediments of the Yellow River Delta and Jiaozhou Bay.The concentration range of CO in sediments was 58.5～540.3 nmol·L-1,controlled by processes such as organic matter degradation and sulfate reduction.In the cultivation experiments,CO was rapidly uti-lized by microorganisms such as sulfate-reducing bacteria,but nitrate had a certain inhibitory effect on anaerobic consumption of CO.In addition,the microbial metabolic rates of CO were affected by envi-ronmental factors such as temperature,water content,and salinity.The results of this study enrich the understanding of the biogeochemical cycling of CO in marine sediments.关键词
