Field tests gave even better results. Researchers applied the freeze-dried bacteria to 3-foot by 3-foot (about 1-meter by 1-meter) plots of soil. They then sprayed urea and calcium chloride on top. Within 24 hours, the top 3 inches (7.6 centimeters) of soil became much stronger. This suggests that freeze-dried S. pasteurii could be a practical solution for stabilizing soil in real-world situations.
Although more research is needed, this is the first successful test showing that freeze-dried S. pasteurii can survive and produce biocement. If this method is fully developed, it could change how construction projects handle cement production, soil stabilization, and infrastructure repair.
