Ground improvement by the biological method is considered to be one of the most preferred sustainable methods for improving engineering properties of soil in comparison to the physical, mechanical and chemical methods. One of such biological method, ureolytic microbial-induced calcite precipitation (UMICP), utilizes urease active bacteria to precipitate calcium carbonate to act as a binding material connecting soil grains. The state-of-the-art presents UMICP process is affected by various parameters briefly categorized under four major sections, viz., biological, chemical, geotechnical and environmental conditions. The critical review of the available literature elaborates the influence of each parameter. Limited studies have attempted to explore the interaction among the bio-geo-chemical parameters affecting the UMICP. With this in view, the current review article aims to elucidate the effect of most adopted factors from different sections to attain efficient process outcome. Further, an attempt has been made in terms of mapping the influence of factors by a process chart, which is deemed to be handy for a qualitative understanding of the interrelationship among these factors. The process chart can be useful for the researchers to understand the way forward in planning the process to scale the experimentation. Challenges to overcome for the sustainable future and possible solutions at field scale have also been described in brief.

与物理，机械和化学方法相比，通过生物方法进行地基改良被认为是改善土壤工程特性的最优选的可持续方法之一。这种生物方法之一是尿素分解微生物引起的方解石沉淀（UMICP），它利用脲酶活性细菌沉淀碳酸钙，作为连接土壤颗粒的结合材料。最新的UMICP工艺受到各种参数的影响，这些参数简要归类于四个主要部分，即生物，化学，岩土和环境条件。对现有文献的严格评论详细阐述了每个参数的影响。有限的研究尝试探索影响UMICP的生物地球化学参数之间的相互作用。鉴于此，当前的评论文章旨在阐明不同章节中大多数采用的因素对获得有效过程结果的影响。此外，已经尝试通过流程图来映射因素的影响，这对于定性地理解这些因素之间的相互关系被认为是方便的。流程图对于研究人员了解在规划流程以扩展实验规模方面的前进方向可能很有用。还简要介绍了在可持续发展的未来中要克服的挑战以及在现场范围内可能采取的解决方案。对于定性地理解这些因素之间的相互关系，这被认为是很方便的。流程图对于研究人员了解在规划流程以扩展实验规模方面的前进方向可能很有用。还简要介绍了在可持续发展的未来中要克服的挑战以及在现场范围内可能采取的解决方案。在定性地理解这些因素之间的相互关系时，这被认为是很方便的。流程图对于研究人员了解在规划流程以扩展实验规模方面的前进方向可能很有用。还简要介绍了在可持续发展的未来中要克服的挑战以及在现场范围内可能采取的解决方案。
