Research on the biogenic-specific morphology of carbonate minerals has made progress in the fields of biomineralization and industrial engineering. In this study, mineralization experiments were performed using sp. MF-2, including its biofilms. The results showed that a particular morphology of minerals (, disc-shaped) was observed in the mineralization experiments with strain MF-2. The disc-shaped minerals were formed near the air/solution interface. We also observed that disc-shaped minerals formed in experiments with the biofilms of strain MF-2. Therefore, the nucleation of carbonate particles on the biofilm templates produced a novel disc-shaped morphology which was assembled from calcite nanocrystals radiating out from the periphery of the template biofilms. Further, we propose a possible formation mechanism of the disc-shaped morphology. This study may provide new perspectives on the formation mechanism of carbonate morphogenesis in the process of biomineralization.
关于碳酸盐矿物生物成因特定形态的研究在生物矿化和工业工程领域取得了进展。在本研究中，使用sp. MF-2进行了矿化实验，包括其生物膜。结果表明，在菌株MF-2的矿化实验中观察到了特定形态的矿物（盘状）。盘状矿物在空气/溶液界面附近形成。我们还观察到在菌株MF-2生物膜的实验中形成了盘状矿物。因此，碳酸盐颗粒在生物膜模板上的成核产生了一种由方解石纳米晶体从模板生物膜周边辐射而出组装而成的新型盘状形态。此外，我们提出了盘状形态可能的形成机制。本研究可能为生物矿化过程中碳酸盐形态发生的形成机制提供新的视角。
