全球气候变化是21世纪人类面临的最大挑战之一。研究和利用硅酸盐矿物风化产生的碳汇一直是学者们研究的重点。岩石的风化，特别是硅酸盐矿物的化学风化，通过将大气或土壤中的CO2转化为HCO3而消耗CO2，HCO3最终沉积为海洋中的碳酸盐岩。这意味着硅酸盐矿物的风化是一个净碳汇，并且已经跨越了所有的时间尺度（Wofsy等人，2001年）和一个调节和控制大气中的CO2量和相关的全球气候变化（Berner，1995年）。硅酸盐矿物在物理和化学作用下的自然风化是一个缓慢、被动的过程。微生物是地球表面系统中最活跃的地质营力之一，对硅酸盐矿物的风化起着重要的作用。在长期的地质演化过程中，微生物的作用导致大气中的CO2转移到碳酸盐岩中，形成了岩溶发育的物质基础和世界上最大的碳库（Lian et al.，2011年）。微生物对硅酸盐矿物的风化作用与微生物对矿物养分的需求密切相关。特别是微生物可以通过调节其代谢途径，在矿物质营养水平较差的环境中驱动硅酸盐矿物风化释放矿物质元素，这是一种用于获得矿物质营养的生理代谢过程（Xiao et al.，2012年a）。微生物可以合成和分泌低分子量有机酸，并通过酸化和络合促进矿物质的溶解（Yao等人，2013年）。* 的协同效应
Global climate change is one of the greatest challenges facing humankind in the 21st century. Studying, and utilising, the carbon sink caused by the weathering of silicate minerals has been a key research focus for scholars. The weathering of rocks, especially the chemical weathering of silicate minerals, consumes CO2 by transforming CO2 in the atmosphere or soils to HCO3 which is ultimately deposited as carbonate rocks in the oceans. This means that the weathering of silicate minerals is a net carbon sink, and has been across all time scales (Wofsy et al., 2001) and one which regulates and controls the amount of CO2 in the atmosphere and the associated global climate change (Berner, 1995). The natural weathering of silicate minerals under physical and chemical actions is a slow, passive, process. Organisms, as one of the most active geological agents in the earth-surface system, especially microorganisms, can facilitate the weathering of silicate minerals. In the long-term course of geological evolution, the effect of microorganisms leads to the transfer of CO2 in the atmosphere to carbonate rocks, forming the material basis of karst development and the largest carbon pool in the world (Lian et al., 2011). Weathering of silicate minerals by microorganisms is closely associated with their demand for mineral nutrients. In particular, microorganisms can drive the weathering of silicate minerals to release mineral elements in the environment with poor mineral nutrient levels by regulating their metabolic pathways, which is a physiological metabolism process used to obtaining mineral nutrients (Xiao et al., 2012a). Microorganisms can synthesise and secrete low-molecular-weight organic acids and facilitate the dissolution of minerals through acidification and complexion (Yao et al., 2013).
