<p>Biostimulation is one of the major approaches of microbially induced calcite precipitation (MICP) technique and has got wide attentions in recent years for the persistent mineralization, environmental compatibility, and low cost. In the current study, the soil retrieved from field was biotreated through biostimulation approach and subjected to drained triaxial tests and isotropic compression tests. Results of drained triaxial tests indicate that the peak strength and post-peak softening increase with increasing cementation treatment cycles (<i>N</i>). As well, the stress–dilatancy behavior is strongly influenced by biocementation levels. The improvement in residual state friction angle and effective cohesion force are dependent on the <i>N</i>, while the peak state friction angle is less affected by the variation of <i>N</i>. The residual state line rotates counterclockwise with increasing cementation levels in both stress plane and compression plane. In addition, results of isotropic compression tests show that the volumetric compression coefficient decreases as the <i>N</i> increases, indicating that biostimulated MICP treatment can significantly reduce the compressibility of soil. The work provides insight into using biostimulated MICP treatment to improve the drain shear behaviors and reduce the compressibility of the soil.</p>
