Factors Affecting Biocementation Process by Micp in Soils

The aim of the paper is to present factors affecting the biocementation process using the Microbially Induced Calcium Carbonate Precipitation (MICP) method in soils. The MICP process is the one where microorganisms are used to precipitate calcium carbonate to improve soil parameters through the bridges formed between soil particles. The most common bacterial strain, with the ability to hydrolyse urease, and in the presence of calcium ions, promotes the precipitation of calcium carbonate, is Sporosarcina pasteurii. The paper focuses on the factors dependent on the soil, treatment method, and the bacteria density determined on the basis of OD₆₀₀. Research on factors influencing MICP in soil is essential for establishing optimal conditions required for the occurrence and effectiveness of biocementation.
