Bio-cementation (the introduction of microorganisms to problematic soils to improve strength and stability) is emerging as an eco-friendly method of soil improvement. However, using spore-forming bacteria in bio-cementation can negatively impact soil microbial flora. New research shows that the use of an indigenous, non-spore-forming bacterium can reduce such effects while achieving the same level of soil improvement. Such methods could support ‘green’ construction and related policy.
