选育碳酸盐矿化菌，利用其诱导CaCO3沉积，采用涂覆法和浸泡法进行细菌矿化试验，最终在大理石样品表面形成一层致密的矿化膜。采用扫描电镜(SEM)和X射线衍射(XRD)对大理石空白试样和处理后试样进行分析，并对矿化膜进行抗酸性测试。结果表明，涂覆法和浸泡法均能在大理石表面粘结一层细小颗粒，形成一层致密、厚度为50~100μm的CaCO3矿化膜。经过覆膜处理的大理石耐酸性能得到了明显提升。

CaCO3 precipitation was induced by carbonate-mineralization microbe using the immersion method and the coating method, and ifnally formed a dense mineralization membrane layer on marble sample surface. The immersed and smeared samples were characterized by scanning electron microscopic (SEM) and X-ray diffraction (XRD), as well as tested the acid-resistance of the calcium carbonate layer. Experimental results showed that both immersion method and coating method can produce calcium carbonate particle forming a layer of dense mineralization membrane of 50~100μm, acid-resistance of the coated marble samples was improved signiifcantly.
