Short summary
Materials, like soils or cements, can require repair. This study used a new bacterium (Sporosarcina ureae) in a repair method called "microbially induced carbonate precipitation" (MICP). In three trials, benefits were shown: S. ureae could make a model sandy soil much stronger by MICP, in fact better than a lot of other bacteria. However, MICP-treated samples got weaker in three trials of acid rain. In conclusion, S. ureae in MICP repair shows promise when used in appropriate climates.
