Nowadays, despite the accepted standard soil improvement methods or utilization of artificial materials such as cement and lime, these procedures are criticized due to detrimental environmental influences caused during their production process and applications; thus, such problems led to increased demand for new environmentally-friendly methods to improve soil properties. The experimental section of the study used sporosarcina pasteurii (bacillus pastteurii) to evaluate microbial-induced calcite precipitation (MICP) on two distinct grains of sand. The effect of temperature and saturation level on the optimization of calcite precipitation produced by Sporosarcina pasteurii was also examined. The findings revealed that most bacterial activities occurred at a temperature of 35 °C and that saturation reduces the efficacy of remediated sand. The results also show that despite their particle size, remediated sands have a better performance in the durability test. These findings indicate that sporosarcina pasteurii in MICP as a bio-mediated treatment approach improved sandy soil’s mechanical characterization and improved soil characteristics, and enhanced wind erosion resistance.
