硅酸盐矿物的微生物风化作用是地球元素地球化学循环的重要组成部分。它甚至可以影响碳的迁移和转化，微生物碳酸酐酶（CA）在这一过程中起着重要作用。然而，是否有多种微生物CA参与硅酸盐风化和碳酸盐化仍然知之甚少。本研究采用基因缺失、过表达和生物信息学等方法，揭示了两个硅灰石CA基因canA和canB在硅灰石风化过程中的功能差异。结果表明，canA与硅酸盐风化有关，并可伴随碳酸盐化作用。然而，canB是A生存所不可缺少的。nidulansin存在于环境条件下（约0.04%CO2，v/v），其中它主要负责细胞呼吸和生物合成。这项研究强调了微生物CA通过硅酸盐矿物生物风化调节大气CO2循环的贡献。它也提出了一个潜在的应用封存CO2通过生化风化。
The microbial weathering of silicate minerals is an important part of the elemental biogeochemical cycle on Earth. It can even affect the migration and transformation of carbon, a process in which microbial carbonic anhydrase (CA) plays an important role. However, whether multiple microbial CAs are involved in silicate weathering and carbonation is still poorly understood. In this work, gene deletion, overexpression, and bioinformatics were used to reveal the functional differences that twoAspergillusnidulansCA genes,canAandcanB, have in wollastonite weathering. The results show thatcanAis involved in silicate weathering and can be accompanied by carbonation. However,canBis indispensable for the survival ofA. nidulansin present ambient conditions (c.0.04% CO2, v/v), where it is mainly obligated to cellular respiration and biosynthesis. This study highlights the contribution of microbial CAs to regulating the atmospheric CO2cycle through silicate mineral bio-weathering. It also presents a potential application of sequestration of CO2via biochemical weathering.
