Microbial induced calcium carbonate precipitation (MICP) is one of the bio‐cementation methods for improving granular soils. This study evaluate the feasibility of obtaining a bacterial solution with high optical density and urease activity by an inexpensive corn steep liquor (CSL) medium in non‐sterile conditions in order to achieve sand improvement.
