The use of a microbiological process to improve soil properties is a cost-effective, non-destructive and environmentally friendly solution for a variety of geotechnical problems that can be used to increase the unconfined compressive strength (UCS) of the soil. In this study, Sporesarcina pasteurii bacteria was injected as a stabilizer to reinforced soil with polypropylene and then the uniaxial strength of the specimens were investigated. The results show that the injection of the bacteria increases the uniaxial strength of fine-grained soil reinforced with the fibers. This increase depends on the duration of treatment, as the duration of treatment increases the effect of stabilization by biological methods.
