MICROBIOLOGICALLY INDUCED CARBONATE PRECIPITATION

摘要

The present invention relates to a method of forming a carbonate precipitate in a porous material, by a microbiologically induced reaction, comprising providing the material with a liquid substrate comprising an microbiologically oxidisable organic carbon source, an electron acceptor and a counter ion for carbonate, microbiologically oxidising the organic carbon source in an aqueous environment thereby forming carbonate, and precipitating the carbonate.
