The past fifteen years have been a rich developing field for Microbiologically Induced Calcite Precipitation (MICP) as an alternative to decrease the hydraulic conductivity of sandy soils or fractured rocks through biocementation formation. While significant development happened, the field still lacks a viable answer for the use of MICP for organic soil stabilization. Sandy soils or fractured rocks have a completely different structure and mechanical behavior than organic soils, which can impact the behavior of biological components and MICP microorganisms. This factor per se changes all the research perspective and demand adaptations different than the ones used for sandy soil or fractured rocks. In the search for answers, this article compiles an extensive and systematic literature review with papers and books from platforms like Academic Search Premier, Web of Science, Google Scholar, 1Search and Gale Virtual -Reference Library, having the selection based on defined parameters and criteria. Focusing on how MICP is a potential solution for unsealed road stabilization, this article discussed the main gaps and constraints that could explain why biocementation still needs extensive research under different perspectives and scenarios. The results suggested that the majority of investigations are at a similar stage of limitation: how to guarantee an evenly spread of biocementation into organic soil at large extensions. The discussion here provided some insights and pieces that can enrich future researches, support the expansion of the development, and improve the understanding of the biocementation process into organic soils and its use for unsealed road stabilization.

在过去的15年中，微生物诱导方解石沉淀（MICP）作为通过生物胶结形成降低沙质土壤或裂隙岩的水力传导性的替代方法已经成为一个广阔的发展领域。尽管发生了重大发展，但该领域仍缺乏使用MICP稳定有机土壤的可行答案。沙质土壤或裂隙岩石的结构和力学行为与有机土壤完全不同，这会影响生物成分和MICP微生物的行为。这个因素本身改变了所有的研究视角，与沙质土壤或裂隙岩石所使用的适应方法不同。在寻找答案时，本文使用来自学术搜索Premier，Web of Science，Google Scholar，1Search和Gale Virtual-Reference Library等平台的论文和书籍进行了广泛而系统的文献综述，并根据定义的参数和标准进行选择。本文重点关注MICP如何作为未密封道路稳定的潜在解决方案，讨论了主要的差距和制约因素，这些差距和制约因素可以解释为什么生物胶结物仍需要在不同的视角和场景下进行广泛的研究。结果表明，大多数研究都处于相似的局限性阶段：如何保证生物胶结物在大范围扩展中均匀地扩散到有机土壤中。这里的讨论提供了一些见解和片段，可以丰富未来的研究，支持开发的扩展，
