硅化微生物结构的鉴定存在争议。为了进一步了解微生物硅化保真度，对现存芽孢杆菌进行了模拟硅化实验。本实验表明，微生物凝固迅速，总体形态得以保留。硅化微生物被双层二氧化硅纳米球包裹，内层保留了微生物的表面结构，而外层仅保留了微生物的轮廓。讨论了该实验对于鉴定硅化微生物化石和重建硅化环境的意义。
Controversies occur in identifying silicified microbial structures.The simulated silicification experiment on extant bacillus was carried to benefit further understanding of microbial silicification fidelity.The present experiment reveals that the microbes solidified rapidly and the general morphology is preserved.The silicified microbe was encrusted by double layers of silica nano-spheres.The surface structure of the microbe is preserved in the inner layer,while only the outline of the microbe in the outer layer.The significance of the experiment on identifying silicified microbe fossils and reconstructing silicification environment is discussed.
