The aim of the present paper was to study the production and properties of iron‐based biogrout. RESULTS Iron‐based biogrout was produced from hematite iron ore and cellulose by associations of iron‐reducing and cellulose‐fermenting bacteria selected from the bottom sediments of the Dead Sea and mangrove swamp.
