Annotated Summary

Mujah, D., Mohamed, S., & Liang, C. (2016). State-of-the-art review of biocementation by microbially induced calcite precipitation (MICP) for soil stabilization. Geomicrobiology. 34. 524-537. Retrieved from www.doi.org/10.1080/01490451.2016.1225866.

This article focuses on reviewing the use of biocementation by Microbially Induced Calcite Precipitation (MICP) for soil stabilisation. Evaluation of biocemented soils was made, and it was found to be highly effective for enhancing the engineering, mechanical and physical properties of the soil, which is important to combating settlement, erosion and liquefaction in soils. Utilising MICP for soil stabilisation over chemical grouting methods are not only cheaper, but also “promote sustainability in tandem with future needs”. The article highlighted that while MICP could relieve “present day concerns in soil improvement”, there is still a need to address several issues such as treatment homogeneity and up-scaling for MICP to be feasible.

The article serves to provide insightful information on the opportunities and obstacles of soil stabilisation using biocementation by MICP. This information in the article had been exceptionally useful for my team’s research topic on using biocementation by MICP to counter settlement caused by nearby underground works. It had also helped to guide our research towards finding solutions to the problems stated in order to make biocementation feasible for soil improvement.

    Dear Chen Wei,

    I enjoyed reading your annotated summary. It was well written and informative. It made me want to read the article myself.

    Best Wishes,
    Wai Yan

    Hi Chen Wei,

    Your annotated summary was very interesting and informative. I did not know that biocemented soils were effective in enhancing the properties of soil. It appears to be quite relevant for your project and serves as a supportive point.

    I look forward to reading your posts in the future.

    Warm regards,
    Muhd Sharifuddin

      Hi Sharif,

      Thank you for taking the time to read my annotated summary! I am glad to hear that you found my summary interesting and informative.

      Like you, I did not know that biocement technology could be applied to soils to enhance its properties, although I was aware that it could be used to produce self-healing concrete. This article hence serves as a eye-opener on the other potential uses of biocement technology and is also a great help in the technical report.

      I hope that the information that you found from the summary could be of use to you in the future.

      Best regards,
      Cen Wei
