摘要:

微生物作为湖泊沉积物碳矿化的核心驱动力,主导有机质降解、无机碳转化与碳酸盐沉淀等关键生物地球化学过程,但其在湖泊碳汇形成中的作用研究仍不充分。以内蒙古呼伦湖为研究区域,综合运用16S rRNA测序、碳组分分析、水化学分析,并结合扫描电镜(SEM)、傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)及拉曼光谱等多种技术手段对沉积物与水样进行系统分析,最后基于分子动力学模拟探讨微生物驱动无机碳沉淀的路径机制。结果表明:内蒙古呼伦湖属于淡水湖泊,其沉积物中存在丰富的微生物群落,主要包括BD2-11_terrestrial_group、Halomonas和Nitrolancea等菌属及藻类微生物; 沉积物中无机碳(IC)含量、总碳(TC)和总有机碳(TOC)随深度的增加而增加,表现出明显的垂向分布趋势; 无机碳的碳同位素组成(δ¹³C)为-19.16‰～-11.39‰,整体偏负,暗示沉积碳酸盐矿物可能源自生物代谢产生的CO₂; 矿物学分析均识别出典型的碳酸盐矿物特征峰,如方解石和白云石; 在含有富里酸的有机矿化体系中,CO^2-₃与Ca²⁺、Mg²⁺更易形成尺寸更大的团簇,且聚集过程明显快于无机矿化体系。

Abstract:

Microorganisms are the core driving force for carbon mineralization in lake sediments, playing a dominant role in key biogeochemical processes such as organic matter degradation, inorganic carbon transformation, and carbonate precipitation. However, research on their role in the formation of lake carbon sinks remains relatively limited. Hulun Lake in Inner Mongolia was selected as the study area; by integrating a suite of analytical techniques, including 16S rRNA gene sequencing, carbon component analysis, water chemistry measurements, scanning electron microscopy(SEM), Fourier transform infrared spectroscopy(FTIR), X-ray diffraction(XRD), and Raman spectroscopy, a systematic investigation of lake sediments and water samples was conducted. Furthermore, molecular dynamics(MD)simulations were employed to explore the mechanistic pathways of microbially mediated inorganic carbon precipitation. The results show that Hulun Lake in Inner Mongolia is a freshwater system characterized by diverse and abundant microbial communities in its sediments, including bacterial genera such as BD2-11_terrestrial_group, Halomonas and Nitrolancea, as well as algal microorganisms; the contents of inorganic carbon(IC), total carbon(TC), and total organic carbon(TOC)all increase with depth, exhibiting a clear vertical distribution pattern; the δ¹³C values of inorganic carbon range from -19.16‰ to -11.39‰, indicating a generally negative bias that suggests the carbonates in the sediments may originate from CO₂ produced by microbial metabolism; mineralogical analyses consistently identify characteristic peaks of carbonate minerals such as calcite and dolomite, further confirming the presence of inorganically precipitated carbonates in the sediments; in organic mineralization systems containing fulvic acid, CO^2-₃ forms larger ion clusters with Ca²⁺ and Mg²⁺ more readily, and these aggregates also nucleate significantly faster than in purely inorganic mineralization systems. In summary, this study further elucidates the mechanism of microbial action in the carbonate pump mechanism of lakes, expands the understanding of the biogeochemical functions of microorganisms in the lake carbon sink, and deepens the comprehension of the coupled process of “lake carbon sink-microbial action”.
